I've been doing weighted single legs squats for a while now and I tend to stay around 50kg weight, going for 5 sets of 5.However, for specific reasons I won't have access to weights for potentially a long period of time.What can I do to replace them?I was thinking maybe somehow attaching my ankles to a box fixed to the ground and using my quads to extend my body(like a reverse hamstring raise or something) But that doesn't quite make up for it.Is there any way to make squats "heavier" without weights or is the SLS/jumping SLS the maximum?
