Food and nutrition are about 70% and liftiing and speed work are 30%. Can’t feed a race car bad gas and same with these high end athletes. Should be drinking Protein shake right after morning workout followed bye egg omelette with broccoli and cheese and fruit. 2.5 to 3 hrs later u need lean turkey burgers or grass fed beef low fat. 2.5 hrs after another shake plus some fruit. Around 6 pm or so last heavy meal with chicken or fish,not farm raised fish either, broccoli or some other low inflammation veges. If ya want to be lean u can have a shake before bed and if u want good weight add another protein meal with some clean carbs like brown rice or my favorite sweat potatoes. Obviously this can vary a huge amount. Just like the s+c coaches should know each individuals weaknesses and makes them strengths, the nutritionist should know each kids good foods and bad foods and capitalize on what they and s+c coaches want each kid to do. ie gain weight in pure muscle or lean muscle or even just gain strength and stay at same weight.
