I’m relatively new to lifting. My workouts comprise the main compound lifts - squats, dead lifts, presses, rows, pull-ups. I don’t do any isolation work for hamstrings or calves. Do I need to add exercises that target those muscles directly or am I hitting them hard enough with the big compound movements? I do both regular and stiff-legged dead lifts, FWIW. I feel my hamstrings working pretty hard during the stiff-legged variation. Any pointers are appreciated.
