Any mid-30's and up guys here still competing in martial arts? I've been training in the martial arts for about 10 years or so. I'm 32 and am on TRT. I always feel beat up and sore. It's funny because before I was on the test I was still sore but could run, sprint, etc. Now on the test/arimidex my back screams whenever I run and I my cardio sucks no matter how hard I push it. I literally get the shakes and feel like I'm falling apart when I push too hard, and it's frustrating cause for me there's no other way than hard lol. Anyway, I was asked and am thinking of taking an amatuer MMA fight but don't know if I can get my body in the shape it was in previously. It's really frustrating. Anybody in a similar situation and want to give advice?
