i am amatuer mma fighter at 155lbs. i have a 6-1 record but havent really fought in any big shows. i walk around at about 157-159 lbs with 6% bodyfat. i have been told by a pro fighter i train with that if i want to make it to the next level in need to go to 145lbs. other people have told me that i too skinny and not to do it. i have never cut weight before. my biggest weakness is that im not naturally very strong. i got a personal trainer now for weight lifting and am getting stronger but still feel that i will be giving away weight to people who cut. my question is..........should i cut to 145? how difficult will it be? opinons?
