I am currently trying to break past scar tissue to get the rest of my flexion. Currently if I strain I can get 120 but not as a functional amount. One thing that seems to help the stretch for flexion for me is the leg press machine. I am able to relax into the stretch and let the weights help apply pressure to bend the knee. However I do not have that machine at home and heel slides are not enough as I really struggle trying to pull past the stiff point against the discomfort. I was wondering what others have found helpful to them.
