hey i ve been weight-training and wrestling for about 2 years and ive started boxing instead of it (wrestling). im interested in changing my body from bigger to leaner. i currently stand 5'11" and weigh 200. my goal is around 180 and to get more definition and visible abs. i eat clean but its been relativley hard to eat less. should i switch more to calisthenic workouts or just less weight? i guess my question is how do i change from bigger to leaner?
