I'm sixteen, 120-125 lbs, 5'7", I do strength training 3 times a week plus walking, but otherwise I don't get out and do much... My body at percentage is also 21.2 (caliper testing at my gym)...
I'm just wondering what my macronutrient breakdown should look like? I'm wanting to lean out a bit, maybe look a little more athletic, if I could do so healthily.
Thank you in advance :D
