Extension of glutes on a machine on all fours

Perform the described movement slowly and steadily while keeping the involved joints aligned. Complete the range without using momentum through the hardest portion. Use a steady tempo: control the return phase in particular and avoid relying on momentum. Exhale through the hardest part and inhale as you recover the starting position.

Check that the movement stays stable in both directions and that the torso is not compensating. The goal is controlled loading of hamstrings and glutes and hip flexors; match resistance and range to a intermediate level and never force a painful repetition. Set the seat, backrest and machine axis before loading it; poor setup changes the path and often creates compensations.
