Hello!
I have this problem with the kneeling achilles stretch: On my left foot, my mobility is good enough so that when I lay my chest on my thigh, it's enough force to feel a stretch in my achilles. My right ankle, on the other hand, is not as flexible and it's really hard to apply enough force to feel a stretch without lifting the heel off the floor.
What would be the best way to go about this issue until the ankle mobility catches up? Should I lift the heel off the floor? Keep it elevated on a weight plate to increase leverage? Anything else?
Greetings
Daniel
