My father has recently written an e-book on hamstring rehabilitation. Although this won’t interest a lot of my readers I wanted to get it out there, both for you and for him. There isn’t really a better place to launch it, and if there are some athletes or sports coaches out there, or people with recurring hamstring injuries, then this should be of interest for you.
He (Loris) is a an extremely experienced fitness and conditioning coach, and has worked in AFL (Australian Football League) and with many sports and athletes at the highest level for over 20 years. He really knows his stuff, especially in regard to athletes, and this manual takes you step by step through rehabilitating a hamstring with a very low risk of recurrence. Hamstrings are pretty tricky to rehab, and people often get it wrong, this provides pics, programs, and step by step instructions the whole way through. Check out more about the Hamstring Rehabilitation Manual here, for a 120 page extensive manual it is very cheap at $19.99.
