I have a herniated disk and just can't seem to be able to find a way to do squats or deadlifts without getting myself into trouble with my back again.
At the same time, I have found myself unsatisfied with the results I have gotten so far with the single-leg deadlifts (bodyweight), leg extensions, lunges, and general bodyweight exercises (e.g., stepups) I have done as substitutes. What I have done with them so far just hasn't given me anywhere near the effect that "big" lifts do.
This is really frustrating because greater leg development is what I would like more than anything else. At the moment, I would like to find a way of doing something that is equivalent to the Velocity Diet workout routine, but without the Romanian Deadlifts, Front Squats and Deadlifts.
I am sure there is a way to get satisfying leg development without these exercises, but I haven't been able to find it yet. Advice from anyone who has been more successful than I would be greatly appreciated.
ps - For the time being, my gym does not have a trap bar
