I am 5'9 and 3/4 almost 5'10 and weight 124-125 lbs when I cut weight from 135. I walk around at 132-137. I do alot of upper body workouts burpes, I can do 500 push ups in a row. I do 100 miles on the layback bike some days while doing curls of 55-60 reps switching arms the whole time. I have a nasty leg kick good top gulitine. my strengh is my striking tho can switch stances easy and strike good from both south paw and reg. I am a righty tho. What sport should I choose and what weight class. I am 34 years old and am noticing Im getting slightly slower then when i was 32-33. Should I just say fuck it and just train for fun?
