I just started lifting to get stronger for MMA. I have an Olympic barbell with 300 lbs and a bench. I intend on doing the big three, but I can't squat safely alone. I realize that no exercise can replace the squat, but is there anything I can do insted that is almost as good? I know I can do bodyweight squats and light weight squats, but is there anything else I'm missing? I already dedlift and bench twich a week with heavy weight and low reps. What is a good stand in for squats? Should I substitute power cleans for squats? Just do bodyweight squats for high reps? Any imput will be helpful.
