Here's Athletic Lab's mikeyoungphd doing some supra-maximal load #squats on the #kBox3 using the arms to add to the concentric force which, because of the #flywheel technology, causes an even greater than normal #eccentric overload on the descent. Despite resisting maximally, take a look at how fast the flywheel accelerates Mike downwards. This type of training is great for athletes. go_exxentric #strength #skwats #fitness #strengthandconditioning #training #iloveAL #PhDswhosquat
