How to do it
Flex the spine bringing your sternum towards your pelvis; the hips stay still
Muscles worked
Mainly abdominales. Train it inside a balanced routine to progress safely.
Recommended sets and reps
As an isolation exercise, it works best in 3–4 sets of 10–15 reps with 0–2 RIR. Use it at the end of the session to add volume without systemic fatigue.
Common mistakes to avoid
- Pulling on the neck with your hands and flexing at the hips instead of curling the spine with the abs.
- Using too much weight at the cost of technique and full range of motion.
- Doing reps too fast, without controlling the eccentric (lowering) phase.
