Firstly I’ve got to give the credit to Alwyn Cosgrove via Mike Boyle for this one. He originally intended for this to be done on a stability ball for stretches such as the hamstring version above.
I’ve been using the bosu with people for the opossite of its design!
It has more stability than the ball for this type of thing. It works great for a squat stretch too as above.
The idea is you get to promote extension/concave back shape while you stretch which is very desirable.
It’s a two in one release to computer posture with the hamstring stretch! Just add in a good hip flexor stretch with an airex pad or a pillow/cushion and a good chest stretch on the doorway to make your bad posture fighting even better!
