i dont like doing legs. so i just do whole body lifts like squats, deadlifts, and olympic lifts.
squats are the best exercise for legs and its also benneficial for the rest of the body.
so when you do squats, think of all of your body growing and dont think of it as leg work.
Since i only do squats i do it very intensely and with a high volume. CHange the reps drastically, add more weight. surprise your body with hack squats, etc.
now talking about hamstrings, just do deadlifts, olympic lifts and they will grow.
Dont think of it as leg work, think of it as whole body work.
