I've been doing weight training for the last 3 years, but this year I just couldn't do gym due to work schedule, so my only option to stay fit is doing some home exercises such as push-ups, pull-ups, chin-ups, dips and abs, and swimming with a trainer telling me what to do, being the swimming the main part of my sports activity. With this said, what should be the kind of diet more apropriate to someone on this kind of sports activity? And how can I aply the knowledge that I have in terms of nutrition (protein ratios per pound of BW, glicemic index and all we need to know to get mass on our bodies) to this kind of activities?
