3DMAPS first or CAFS first?
If you are looking for an assessment-based program, then the 3DMAPS is the way to go. It will give you a couple quick and effective movements to find deficiencies in someone’s body so you can work towards symmetry.
If you are looking for a way to take any exercise and change it up into something new, and to have access to millions of different exercises, then CAFS is the way to go. It gives you ways to tweak any exercise to make it different, more suited for the client in front of you.
