Lifting weights

It is actually a misconception that lifting heavy weights will make you grow big muscles and become slow.

It actually depends on the kind of weight training you are doing. If youre doing it right, weights can increase your power, endurance and speed.

If you are doing bodybuilder's programme like (Monday: Chest, Wednesday: legs, Friday: Back, etc.) then obviously youre going to be packing on alot of dead weight muscle.

Nowadays, as opposed to the previous generation, some thai  gyms are incorporating weights into ther muay thai.
Times are changing.
