Replying to Kneesovertoes guy

Anyone else tried this, got acl surgury last June, started his program on febuary 8. I could not get my heel to butt and was told that I never will. Three weeks in I have full flexion of my knees and can sit on my feet. Knees feel amazing. I would highly recommend this program to anyone who has had knee surgury or has knee pain. Shit works real well. Patellar tendinitis is slowly going away too. Definitly talk to a P.T first. and dont start it unless you are at least 6 months out of surgery. @kneesovertoesguy on instagram.
