Mechanics

Pattern: spinal flexion
Equipment: machine, bodyweight

Equipment context

The machine fixes the movement path, reducing stabilizer demand and letting you focus on the target muscle. Bodyweight exercises need no equipment, but progression depends on leverage and position rather than added load.
