Hello, so I'm now doing the cossack squat/twisting squat exercises.
My problem is that I can't go down into the squat low enough until I raise my heel from the ground. I see in the videos that the heel raises a little bit, but in my case, I have to raise it a lot more in order to go lower. I guess my Achilles tendon is too tight.
Is this acceptable? Or should I continue doing this exercise until I can go into the squat with the heel completely flat on the ground.
Thank you,
Leonardo
