I'm a bit of a noob in this forum, but I've always been into fitness and lifting. Trained TMA a few years ago but I've lifted weights my whole life.
I've always had the impression that lower reps higher weight was the way to gain mass/ build muscle with the trade off being reduced speed and range of motion.
Because of my own body type (long, wiry) I've always lifted low to medium weight with high reps thinking I'm building some strength but more importantly muscle endurance and still keeping full range of motion and explosiveness.
I agree that stretching is vital, it's always been a part of my routine. I'm still convinced that when I do lift low/reps- high/lbs. I feel limited in my speed/R.O.M. Is it a matter of body type or what?
