Can it make you stronger and bigger and will you be able to know how to fight from it? Or do you just lose weight, get skinnier and toned up and it's only for getting fit not for being a better fighter? I want to get bigger like atleast 20 lbs heavier, I weigh 155 lbs right now and im 5'6, if not that then looking bigger then I am right now and losing some pounds is fine with me. So can someone please explain to me this whole cardio kickboxing thing and how it can affect someone?
