I found out yesterday that the ONLY leg extension/curl machine in my antiquidated gym has broke. I doubt they will fix that machine in the near future. So now my question is... what options do I have for substituting the leg ext/curl superset segment in my routine? The only other leg machine is a seated leg press. I've got a power rack and barbells/dumbells of course.
Should I sub in a squat variation? Or perhaps lunges?
