I’m starting this new workout this week and I have a question about legs. It calls for squats, leg presses, leg extensions, ham. curls(I substitute stiff-legged deadlifts,) and a couple of calf exercises. Is there enough work for the hamstrings? Do squats or leg presses hit the hams?

If you go deep enough on the squats it does. Usually my hamstrings are more sore than my quads and my leg workout is just about like yours. Leg extensions first for a warmup, not too heavy. 4 sets of 8 squats, 4 sets of 8 leg press, 4 sets of leg curls, 3 sets donkey calves, 2 sets seated calves.
