i have been training my stomach muscles for a long time as abs are a big part of power punching. i have quite strong ab muscles but now i face the problem of being unable to see them unless i have just done situps. i am not fat i am average. Ive just turned 15 and weigh almost 10st and am 5'11. i would like ways for my stomach muscles to begin to show so that i have more power in my punches and trainers in the gym take me more seriously as i am more chiselled and likely to be a good boxer. any help and advice given to help my stomach muscles show would be much appreciated and i take training very seriously and am committed so am willing to start and stick to most things. thank you very much for any help
