i just train smart these days, no throwing the weight around,total control. its less likely u will tear a muscle when u r controlling a weight from start to finish, but people wanna play the numbers game whether it b reps or weight n usually that results in sloppier form.i just got back from gym doing legs,i squatted 275 for 4 sets of 12 but the reps where slow,3 seconds down and 3 up.i go ass to calves rock bottom and when u do that u dont need tons of weight just intensity and focus and u can build some nice wheels,i threw in some leg press with feet 6 inches apart,needs toch chest to get full ROM and i bring my toes off the platform in top position and squeeze,i learned that from gaspari back in the day,then its seated leg curls,extensions and lunges,im fucking spent now its time to smoke a doobie and take shower and eat some good quality food like a baked sweet potatoe and a can of sardines in hot sauce ;)not bad for almost 50yrs old in afew months
