Hey All- I've been having a general flexibility discussion over in the new user introduction sections here: http://www.martialartsplanet.com/forums/showthread.php?p=10550429#post10550429 First of all feel free to say hi to Dommo7 over there! I also wanted to take the conversation public a little bit, and I do apologize if stretching machines have been covered before. Our conversation was meant to be broad, from my point of view, but I also think some specific examples form others who have successfully used a stretching machine will better answer his questions. Such as: How many times a week to use a leg stretcher How long did it take for you to see results I of course recommended light stretching every day, especially since he is also playing high school football. My general advice for the machine was to do 2-3 days per week of the machine, to allow time for your muscles to repair. Now if there is anything more specific, if you agree or disagree with my advice, or if you have any personal testimonials for or against the leg stretching machines, please post!
