These tiers compare demands within this family, not universal safety or a mandatory sequence. Load, range, balance and your circumstances can change difficulty. Choose deliberately; pain does not select a progression.

How to move
Hang from a bar in an overhand grip, the legs together.
Lift the straight legs in front, curling the pelvis, until the feet come up toward the bar.
Lower slowly to the dead hang without swinging.
Form cues
Curl the pelvis rather than just lifting the legs.
Stop each rep still before the next.
Practice and cautions
No universal dose is assigned. Choose a manageable amount for your current capacity, leave room for controlled repetitions, and allow recovery. A clinician’s individual plan takes priority.
This is movement education, not an assessment or treatment prescription. Stop for sharp or increasing pain, dizziness, numbness or tingling; seek individual guidance for symptoms, injury or restrictions.
