So recently I've gone back to kickboxing, I train 3 times a week (75-90 minutes per class). I'm 1.81 and 81kg but I got a significant amount of body fat and I wanna burn it down. Any tips on the diet? How many meals a day, what kind of meals etc? Also what other kind of exercise on day off can I do to help the process? Any pull ups etc? PS: I got some whey protein left from my brother (gold standard from optimum nutrition). Would it help w/ kickboxing or it doesn't really help on that kind of activity?
