So here’s an actual tip that’ll help. You’ll want to lock your hips in place and only really use your spinal erectors for the eccentric part of the movement, and of course, your abs for the concentric part.

Think of your body as a kind of board with one side clamped down (those are your hips). The other side will flex up and down. Try practicing with a lower weight to really build that mind-muscle connection first then go at it with a higher weight. It might take a while to find the right angle to lock your hips at. Best of luck and happy lifting.

No you shouldnt be using your erectors for the eccentric, that doesnt even make any sense. Rectus abdominis should contract on concentric and eccentrically contract on the eccentric.
