Instructions
Preparation
- Sit in machine with feet on platform, back under padded lever, and hips against back of seat.
Execution
- Extend lower hips and low back until extended. Return and repeat.
Comments
- Those with limited hip flexor flexibility may need to stop before full exension on this particular type of apperatus (fulcrum near hip). Full range of motion will vary from person to person. Many machines may not sufficiently stabilize hips or their fulcrum may be near hip's axis. In which case, synergists muscles become primary movers and erector spinae becomes a stabilizer (Graves JE, et. al. 1994). See alternative back extension with hip stabilization.
