How to do it
- Adjust the seat and pad so the roller sits across your mid-back.
- Sit with your feet planted and cross your arms over your chest or hold the handles.
- Push the pad back by extending your spine under control.
- Return slowly to the start without letting the weight drop.
Form cues
- Move slowly; this isn't a power exercise.
- Finish with your torso upright, without leaning far back.
- Moderate weights and higher reps.
Common mistakes
- Swinging the weight: your lower back doesn't like jerky loading.
- Overextending at the end: finish in a neutral position.
- Going heavy from day one: start light and progress gradually.
Sets and reps
2-3 sets of 12-15 reps with 60-90 seconds of rest, at the end of your session.
