NASM Certified Personal Trainer
NASM-certified trainer and lifelong athlete turned muscle nerd. I grew up playing soccer and baseball on a high level in the Netherlands, but once I found the gym at 21, I got hooked on the process of building strength, size, and discipline through training. After 15 years of hypertrophy work, I’ve learned that results come from smart programming, consistency, and respecting recovery, not chasing every new trend. I coach with a science-backed, no nonsense approach, helping people build muscle, move better, and stay strong for life.
I’m also educated in osteoporosis and osteopenia training, because getting older doesn’t mean getting weaker — it means training smarter. Lift hard, stay sharp, and make progress that lasts.
