I can do hamstring curls, the weight i use for that is about 1/5 of what I do for leg extensions. I can squat relatively heavy and feel it all in my hamstrings and glutes with very very little quad activation. I figure this is an indication of weak/crappy hamstring flexibility.
Well I always follow a relatively low carb diet. I eat roughly 200 g of protein, 100-200 g of carbs and 50-90 g of fat. I'm 5'9 200 lbs, thighs are 25", calves 17", arms, 17", chest 48", waiste 35"
What is APT? Think it may be just not enough stretching/warm up or not enough food?
I wouldn't call it an injury so much as just a lagging bodypart. If someone knows a good warm up and routine to bring up my glutes and hams i'd be grateful
