All clients deserve a challenging workout
even if they don't have access to equipment

We know how challenging it can be to come up with effective progressions if equipment is limited. To make matters worse, the internet is full of exercises that look cool, but their benefits are unclear. 

 That is why Karsten created the science-based, yet practical, Ground Based Abs.

Karsten Jensen's Ground Based abs is both effective and educational. I have been in the fitness industry for over 20years and I can honestly say that it has been a while since a core workout has challenged me in the way that Ground Based Abs did. It left me sore and aching for more. It is with confidence that I can recommend this program to trainers to better their skill-set and challenge not only themselves, but their clients as well. Thank You Karsten for developing this effective workout that can be done at home.
