Ok so im 20 years old and Ive been thinking about getting into Muay Thai for a while now. I found 2 gyms in Houston using the national muay thai web page thingy. Just kinda worried about my hamstrings hurt them twice running track in highschool and they still give me crap sometimes. Was thinking about going to a doctor and seeing what he had to say about it before I did it. So does anyone know any good rehab I can do for my hamstrings until then?
