I've been doing quads and calves on Monday and hamstrings and calves on Thursday but when ever i do hamstrings my quads are still very sore and hurt to touch. So i cant do lying leg curls or seats leg curls. The reason I've been doing hams and quads separate is because i just get to sore and tired to do both. So i would rather split it up so i could get two good workouts. But i haven't been able to. What would you guys recommend i do?
