I use to stretch my hams and quads every other day and have for about 36 years. About three months ago my hams and quads started to tighten to the point that it hurts to walk. I had to start stretching every day, I use to stretch them for about 30 seconds every other day, now I stretch for 60 seconds every day. Each day they are so tight I feel like I never stretch them but they loosen up. If I miss a day my hips hurt if I miss two days I wince when I walk. I did not injure them, I am 56 years old. I no longer run but do ride a mountain bike and use my Boxflex as well as jump on a trampoline.
Maybe its just AGE but I hope not.
Does anyone have any ideas?
