leave the cutting and bulking cycles to the professional bodybuilders. Just make an effort to clean up your diet - increase your protein (1g per lb of your bodyweight a day), and cut out the refined carbs and vegetable oils.
if you do that, lift weights a couple of times a week and play all that soccer you will lose fat and build some muscle easy enough.
Really make sure you're hitting your protein target. That's important.
Also, don't worry about your bodyfat percentage. Fact is, people are terrible at telling their bodyfat percentage, and usually when someone thinks they're 15 they're actually close to 20. Everyone does it, myself included. How you look in the mirror and how you're performing in the gym are a much better indicator of your progress.
thanks for the answer!
with bulking/cutting i mean at cutting -500 kcal and at buling +100-200 kcal or so. no freaking cuts with 800kcal or bulks with 4000kcal or so.
yeah, im always eating very healthy and trying to reach a high g/lb protein value.
and what about which exercises and how many sets? any suggestions?
