@Taylor Boylan you can put something soft under your tailbone and maybe don’t go as far down, when you feel your back arch that’s how far you should go down! This keeps that pelvis nice and grounded and doesn’t compromise the spine by going into an anterior tilt/booty popping. Other modifications: alternate legs, bend the knees or placing your hands on your hips to keep it supported (if you need extra support you can always use a dumbbell over your hip bones to keep it grounded). If this is from an injury, I don’t recommend using the dumbbell… just modify as I said above keeping the knees bent, adding something soft below the pelvis, and not going too far down or even alternating legs. If you feel anything sharp or painful I would avoid this exercise completely!
