Hi, How Can We Help You?

Category Archives: Muscle Gain

With so many various types of exercise available, deciding which one is best for you and your goals can be difficult. You might be wondering if you should do Low-Intensity Steady State (LISS) cardio or High-Intensity Interval Training (HIIT) cardio to grow muscle and burn fat (HIIT).

To answer this, you must first know the distinctions between LISS cardio and HIIT cardio.

What is LISS Cardio?

LISS, or low-intensity steady-state cardio, is a kind of aerobic (“with oxygen”) exercise. LISS is generally conducted at a constant tempo for 30-60 minutes with little variation in speed or intensity. 


Advantages of LISS Cardio Training

  • Less strenuous 
  • Lower chance of injury
  • Improved early fat burn

Disadvantages of LISS Cardio Training:

  • Extended sessions
  • Less motivated to exercise
  • Only burns calories during exercise

What is High-Intensity Interval Training (HIIT)?

HIIT is an abbreviation for high-intensity interval training, which requires building up a sweat rapidly through short bursts of intense exercise, then resting for a slower recovery time before repeating the practice.

Advantages of HIIT Training:

  • Sessions that are shorter
  • More effective for long-term fat loss
  • Aids in muscle retention

Disadvantages of HIIT Training:

  • More strenuous on the body
  • Increased recovery time
  • Intimidating for newcomers

The Primary Distinctions Between LISS Cardio and HIIT

Intensity of Activity


  • LISS cardio is significantly less intense than HIIT training.
  • This corresponds to 60-70 % of your maximal heart rate.


  • A HIIT exercise is designed to push you to your maximum tiredness level.
  • This would include executing as many reps of each exercise as feasible with maximum intensity.

Duration of Activity


  • LISS cardio is often significantly longer than HIIT cardio since you are exercising at a pace that you can maintain for long durations.


  • HIIT, on the other hand, is significantly shorter in duration since you are training at a pace that cannot be sustained for more than 30 minutes.

Calories Burnt

  • According to studies, doing a HIIT session burns more calories than doing LISS exercise for the same length of time.

Which is Better – HIIT OR LISS?

If you find yourself missing exercises because you’re afraid of the hour-long jog, consider HIIT. If you dislike the intensity of HIIT, try LISS. However, it is a good idea to practice both on alternate days and cycle between the two so that you can get the advantages of both.

Maintain adequate recovery time, remain hydrated, and have fun!

With toned abs, biceps for days, and an amazing physique that’s always in prime superhero shape, it’s a no-brainer why Chris Hemsworth is the dream of every gym-goer. 

The Marvel actor’s huge muscles and acting chops have earned him international stardom, and if you’re wondering just what makes him thick, pun intended, read on to uncover Chris Hemsworth’s workout routine and diet plan. 

Long-time personal trainer and close friend Luka Zocchi was kind enough to spill the beans, giving us a rare peek behind the curtain of the Avengers star training. Our talented Personal trainers San Diego were on hand to curate these revelations, putting together this exclusive Chris Hemsworth workout plan and diet that’ll turn you into Thor. It’s a 5 day-a-week program that, we must warn you, isn’t for the faint of heart. 

Eat like Thor. The diet plan: 

The Aussie actor’s diet plan has varied drastically over the years depending on his roles. However, we bet you aren’t here to learn how he slimmed down to fit characters in Rush, rather you’d like to know how he gets his Thor body, which by the way he maintains by fueling on 4,500 calories a day. 

Here’s what his on-set Chef, Sergio Perera says the big fella eats on the daily. 


  • On most mornings (typically around 7 or 8 AM), the dashing star kicks things off with a green power shake protein.
  • He switches up his starter meal either for an almond banana shake or frozen & raw cacao berry shake spruced up with a touch of dates, chia seeds, and coconut oil on Thursdays and Fridays respectively. 
  • Hemsworth follows up his 8 AM meal, with 2-3 fried/poached/scrambled eggs at 10 AM, alternatingly paired with wholegrain toast, savory porridge, warm spinach, and fresh berry yogurt on other days of the week. 


  • He hits the gym at 12 PM on most days for just an hour, then proceeds to a post-workout shake comprising of BCAAs, Vitamin C, ice water, and vegetable protein 
  • At 3 PM, he opts for 8oz grilled chicken on Monday, complemented by rocket salad, salted apples, nuts, and crispy sweet potatoes
  • On Tuesdays, he goes for steamed rice (half a cup), grilled pumpkin, and 8oz eye filet,
  • Meanwhile, Chris’ Wednesdays (3 PM) are for a homemade frozen green bar encompassing, cucumber, pumpkin, cauliflower, and bee pollen, all blended into one magical concoction 
  • At 4PMs on Thursdays, he switches it up with dried fruit accompanied by a snack of nuts and beef jerky. That is preceded by wild rice pilaf, vegetable salad, and 6oz grilled ribeye steak at 2 PM
  • On Fridays, Chris digs into steamed rice once more, and sesame chicken salad consisting of pickles and sprouts


  • Dinner starts at 5:30 PM on Mondays, with Chris sitting down with cherry tomatoes, tuna, and 2 rice crackers. He follows this up with 8oz white fish at 6 PM and yogurt-pawpaw dessert at 9 PM 
  • On Tuesdays, the Marvel star switches his appetizer for vegetable and chicken soup, followed by 8oz white fish for dinner, and BCAAs consisting of Zinc and Magnesium supplements at 9 PM. 
  • Roasted carrots and grilled lamb chops comprise dinner on Wednesdays, which he washes down with BCAAs, and honey-sprinkled yogurt 
  • BCAAs round off a dinner of baked potato, roasted brussels sprouts, and steamed snapper fish on Thursday
  • 8 oz of grilled mahi-mahi completes the Chris Hemsworth diet plan on Friday, paired with Caesar salad (non-dairy), roasted tomato, and grilled asparagus 

Chris Hemsworth Diet Plan

A word to the wise though. Everyone has unique dietary needs, so what worked for Chris may not necessarily be great for you. So let our San Diego personal trainer help you fashion a killer personalized diet plan. 

Train like Thor. Chris Hemsworth’s workout routine: 

Well, there are two sides to the coin that is the Chris Hemsworth training routine, aptly billed as the Thor workout program. 

On the plus side, it’s quick and fast and you’ll be done in just an hour. The bad news though: it’s one hour of intense physical workouts that will sap the soul out of you. Are you up for the challenge? Here goes the ultimate San Diego fitness journey that turned man into god: 


Mondays are for abs, back and chest workouts, and here’s how the God of Thunder gets it done: 

  • Barbell bench presses- 5 sets of 12,12,10,8 and 6 reps
  • Hammer strength rows, bent-over rows, and dumbbell flyes- each 4 sets of 12 reps
  • Weighted pull-ups and weighted dips- each 5 sets of 15,12,10,10 and 8 
  • 60-second planks for 1-3 sets
  • Cable crunches, hanging leg raises, reverse crunches, and sit-ups- each between 1-3 sets of 13 reps
  • Oblique crunches- 3 sets of 12 reps for each side

Phew! That’s quite the workout for just one hour.

Chris Hemsworth Pushup


Life’s too short to skip leg day, and Chris likes to get in the following on Tuesday: 

  • Hamstring curls- 3 sets of 20 reps
  • Stiff-legged deadlifts- 4 sets of 12 reps
  • Barbell squats- 5 sets of depreciating sets, namely 10,8,8,6, and 4
  • Seated leg curls and leg extensions- 3 sets of 20 reps

It’s abs and arms days for Thor on Wednesday, when he does: 

  • Weighted chin-ups- 5 sets of 15, 12,10,10 and 8 reps 
  • Barbell French presses, cable tricep extensions, hammer curls, and barbell curls- each 3 sets of 10 reps
  • 60-second planks for 1-3 sets
  • Sit-ups, reverse crunches, and hanging leg raises- each 3 sets of 12 reps
  • Oblique crunches- 3 sets of 12 reps for each side


The Aussie superstar turns his sights to back, shoulder, and chest workouts on Thursday, spanning: 

  • Barbell bench presses- 5 sets of 12,12,10,8 and 6 reps
  • Dumbbell flyes and bent-over rows – each 4 sets of 12 reps
  • Bent-over lateral raises- 3 sets of 15 reps 
  • Dumbbell shoulder presses- 5 sets of 15,12,10,10 and 8 reps
  • Lateral raises and front raises- each 4 sets of 12 reps

Chris Hemsworth Dumbell Workout


Finally, the MCU sensation rounds off his week strongly with the following routine:

  • Barbell squats- 5 sets of 10,8,8,6 and 4 reps
  • Stiff-legged deadlift- 4 sets of 12 reps 
  • Seated leg curls, leg extensions, and hamstring curls- 3 sets of 20 reps
  • 60 second-planks of 3 sets
  • Sit-ups, hanging leg raises, and reverse crunches- 3 sets of 12 reps apiece 
  • Cable crunches and sit-ups- each 1-3 sets of 12-15 reps
  • 3 sets of oblique crunches with 12 reps per side. 

In terms of Cardio, Chris Hemsworth loves to surf. If that’s not your cup of tea, you’ll be happy to know he also does: 

  • Assault bike sprints
  • Treadmill sprints
  • About 15 minutes apiece for jump ropes, pads, and bag (cardio boxing)

Chris Hemsworth Cardio workout

The general rule of thumb is 45 minutes of cardio, although your female personal trainer San Diego may recommend otherwise to fit your goals. 

It’s no walk in the park- but it’s darn worth it!

Chris Hemsworth’s workout routine takes quite a lot of work and mental fortitude. You’re going to want to throw in the towel, and it won’t be easy but you’ll sure love your reflection in the mirror at the end of it. If you require an experienced partner to help you stay the course, our gym in San Diego has all the equipment and expertise you need. Get in touch today for your personal trainer San Diego.

You’re probably well aware that building muscle equates to better health. However, do you know the exact reasons why? Is it worth knowing the answers? We think so and we think the below information will definitely pay off. Also, what could possibly be bad about more knowledge, especially if it directly pertains to your fitness goals?

Ultimately, we all want the same goal: optimal health. Any personal trainer San Diego Ca says as much, and those who have enjoyed the immense benefits will undoubtedly agree.

So before you start searching for outdoor gyms near me and readying yourself for the grind, brew a cup of coffee or tea first and take the time to equip yourself with some golden nuggets of knowledge about muscle-building, here are the top 8 reasons for building and maintaining muscle mass.


Many San Diego fitness trainers are all too willing to recommend strength training to their clients because it not only builds muscle mass but serves as a cardio routine as well. You might argue that almost any kind of exercise has holistic benefits. There are still cardio workouts that help you develop muscles.

However, muscle-building and strength training as a whole clearly stand out because of their more pronounced benefits on the heart and lungs. This is despite most strength workouts being considered as low-impact cardio exercises. This really shouldn’t be a surprise since, even with continued movements and minimal rests, you get to increase your heart rate every time.

There are even studies that prove that it’s just as good for promoting heart health as any kind of cardio workout. This is why muscle-building is almost always included in any elite personal training San Diego program.


We tend to overlook the importance of having the right balance as we do our daily activities. In fact, without proper balance, we won’t even be able to do something as essential as walking or standing! Many seniors also tend to have a higher risk of suffering falls because of poor balancing abilities…as a result of weak muscles.

On the other hand, posture not only helps you look better but may even take care of chronic back pain issues you’ve been dealing with. Having poor posture is a tell-tale sign of low strength endurance since plenty of muscles are typically involved in maintaining good posture.


Any expert weight loss trainer in San Diego will be all too willing to underscore the importance of strength training in boosting one’s metabolism. Incidentally, if you happen to be a foodie, did you know that maintaining muscle mass requires more calorie intake?

Most of this is rooted in the fact that any muscle you develop only adds to your basal metabolic rate (BMR). The latter basically dictates the number of calories you need to take in just to maintain your body’s optimal functions. So you can only imagine the boosts in metabolism you’ll get to enjoy if you continue building muscles and working out in gyms in San Diego.


Much like any kind of exercise, for that matter. After all, strength training also triggers the release of endorphins, which are hormones that help you deal with stress and worry by boosting your mood. You probably know by now how much of a quicksand depression and low self-esteem can be.

If you happen to be suffering from one or more of these conditions, know that there’s always an opportunity to help you combat it through working out. The best personal trainer San Diego will always be there to lend a helping hand to motivate you and, hopefully, come out as a new, more refreshed person!


Just ask any personal trainer San Diego about the importance of muscles in decreasing the risk of injury and chronic pain, and chances are, he or she will point this factor out. At the core of strength training is improving movement. Without it, how can you go about with your day-to-day activities? And even if you can, must you really endure unnecessary pain every time you do anything?

As you keep performing strength training workouts like lunges and squats, you only do your joints a load of good. In turn, this only makes you more amenable to performing daily activities without the usual inconveniences.


And nowadays, who doesn’t want to be more disease-resistant? How exactly does your building muscle provide a better shield against illness? Well, most of it stems from the general way you’re keeping your body stronger as a result of your strength training. The more you build muscle, the more you’re giving your body the fuel it needs to keep up with the demands of everyday life and whatever challenges come your way.

We don’t need to look further than the link between muscle mass and diabetes to drive this point further. Did you know that the more muscle tissue you have, the less load you take off your pancreas in managing glucose in the blood?

So the next time you’re hesitating to search “gyms near me” because of a lack of motivation, just remember this fact and the terrible consequences of uncontrolled diabetes. Chances are, you’ll be suiting up in no time.


Optimal bone health is just as vital as building muscle. Fortunately, you’re not actually neglecting your bones each time you pump iron. In fact, it’s the opposite since strength training also boosts bone density.

For older women who are prone to getting osteoporosis, this opens up an opportunity to prevent that from happening altogether. Keep in mind that if you’re a woman yourself, your estrogen levels tend to take a nose-dive during and after menopause. This only makes your bones weaker, which necessitates taking active steps to keep them strong.


With all these advantages taken together, it becomes clear that muscle-building lends itself to promoting overall well-being. In short, it’s one of the healthiest routes to take. And if there’s one other factor that’s readily associated with health, it’s longevity. This topic has been featured extensively on mass media platforms.

It may not be the sole factor, but the way strength training aids in cardiovascular health and building endurance does keep the risks of chronic diseases down. By no means is it a magic bullet as well. However, now that you know knowing you can add years to your life if you start building muscle NOW, would you still willingly skip out and not train?


What’s good is that strength training can be performed anywhere, in an outdoor gym in San Diego or in the comfort of your home. You may even do it in an online session with your favorite personal trainer San Diego. This pretty much guarantees that there is no room for alibis as far developing muscles. Considering the state of these times, we can even argue that any type of exercise already serves as a ready boost for everyone, so start today!

Muscle building, at the end of the day, comes down to two important factors: diet and exercise. It may seem basic and simple, but once you break it down, it really does come down to these two aspects. However, while simple this does not mean it is easy, it’s how you plan and implement your diet and exercise that makes the difference. This is where an experienced personal trainer can greatly benefit you.

Iron Orr Personal Fitness Trainer San Diego can back this up with countless overwhelmingly positive testimonies from clients. At Iron Orr Fitness, we are more than proud of what we have helped our clients achieve.

This is why to give back to everyone, we’ve compiled a list of invaluable tips from our very own San Diego Fitness Trainers on how to go about with your workouts and dieting if your aim is to gain muscle mass. Here they are as follows:


If your goal is to attain lean muscle, it won’t hurt to truly be in the know when it comes to the specific calories you need to take in every day. The calories needed is calculated from your TDEE (Total Daily Energy Expenditure). In order to gain lean muscle mass, you must consume a slight surplus above the amount of calories burned in the day (TDEE).

It’s not even about going all in and calculating your macros (though that will definitely be effective, too). Rather, it’s concerned with knowing how much protein,  and minimum calories you need in order to maintain that surplus. What’s good is that there are numerous ways nowadays for you to do this. You can:

  • Go the traditional route and take the time to keep a record of your calorie intake.
  • Use an app that will make it easy for you to log your calories and access them for convenient reference.


Since protein is the building block of muscle, it’s only right to keep this as high as your body needs to boost muscle gain. On average, 1 gram per 1 lb of body weight is the recommended intake for adults. But, everyone will be individual so It won’t hurt to take the time to experiment or ask a Personal Trainer San Diego about the right course to take.

Be mindful of your protein sources. Lean beef remains the most ideal option when it comes to dietary sources. This is followed by chicken, eggs, tuna, oatmeal, among others. If you’re having a hard time incorporating more protein into your diet, it won’t hurt to rely on good, old protein shakes to make up for deficits.

Always take note of what’s available to you with your pre-existing conditions factored in. If you happen to have ulcerative colitis, for instance, then your options may be limited to lean meats and eggs alone. 


This is a concept in Elite Personal Training San Diego that essentially means you incrementally increase the intensity of your workouts. It’s about willingly challenging and stressing your body as you train since muscle growth is triggered by these stressors.

Is it any wonder then why Gyms in San Diego are often full of people pushing themselves to new heights? Chances are, they’ve already been advised by their personal trainers that this is the way to get results.

Do take note that this should always be done gradually. The increase should include factors such as intensity, frequency, and volume of workouts as time passes. Admittedly, it could be hard to do this without the guidance of Personal Training Gyms in San Diego. Injuries remain a high risk should people decide to go this route so consult a personal trainer before you increase your reps and intensity.


Before you start searching for “gyms near me” with the intention of training in it every day, know that rest is just as important for developing muscles. For one, you’ll only be putting yourself at a higher risk of injury if you do so. Once it does hit you, you’ll only end up being out for a long time, which will only put all your hard-earned gains to waste.

Aim to achieve REM sleep every day as much as possible. Five hours of it alone can do wonders for your body. Always allow time for your muscles to fully recover before going into your favorite Outdoor Gym San Diego all freshened up and ready to tackle newer, harder workout challenges. 


As long as your workouts are not causing limitations to your movement capabilities, then that’s a good sign that you should continue doing the workout sets you’re doing. Finding a good range for sets and reps that allow you to be 2-3 reps from failure(with good form) is ideal. For starters, it’s always better to start slow and build up from there.

A majority of workouts should be done with 70%-85% of your 1RM(1 rep max) and limit your reps to 8-12 and sets below 4. The key is for you to adopt the thinking that a little mild soreness will go a long way while making sure that you can still handle the workout routines you do.

The need for fitness has never gone out of demand. Especially after the COVID-19 pandemic, the awareness for a healthy fitness regimen has increased to the point that it is a must-have for all of us! Many people usually do not take into account the need for a personal trainer for staying fit and in shape. The idea that you can be fit on your own is true…only to a certain extent. In order to achieve the best results, you will need a personal trainer; mostly all professional athletes have personal trainers and you deserve to get one as well.


We, at Iron Orr Fitness, provide you with the best fitness personal trainer San Diego. Our task is to ensure that you achieve your target by following the right techniques and diet. So, if you are considering Personal Trainers in San Diego, then look no further. We will provide you with the reasons why we can be the best choice for you. Thank you for reading.
