exactly, not ! It’s a compound exercice that activates a bunch of muscles. If they have a weak back, they will feel it more until it gets stronger
make sure your back is straight with your shoulder blades pulled back and lock your back at the bottom where it meets your ars (like a hinge) and arc it like you’re about to receive an enema or about to take a poo at a nasty toilet you don’t want to sit on 😂. Then kind of thrust as you come up with your pelvis and squeeze your butt cheeks together very hard.
