Raising and lowering the upper body in a supine position (trunk bend) ► sit up

Individual work

Sit with your legs up (legs pointing towards the wall bars/tree), upper body slightly tilted backwards, arms stretched vertically upwards, elastic band attached to the wall bars/tree at hand height, grasp the band with your hands, lower your upper body towards the floor (do not lay it down completely), move your arms from a vertical to an almost horizontal position (from holding them up to extending your upper body), raise your upper body back to the starting position with the support of the elastic band.

Attention:
Never fully lower your upper body (maintain tension).

Lighten:
Choose an elastic band with greater resistance.

Harden:
Choose an elastic band with less resistance.

1 elasticated rubber band
