Set up a sturdy horizontal bar, rings, or suspension trainer at approximately waist height.

Position yourself underneath the bar/handles, facing upwards.

Grasp the bar/handles with an overhand grip, hands slightly wider than shoulder-width.

Extend your legs, keeping your body straight from head to heels (or bend knees for easier variation). Engage core.

Pull your chest towards the bar/handles by retracting shoulder blades and bending elbows.

Keep body rigid and elbows relatively close.

Pause briefly at the top, then slowly lower back to the starting position.

Repeat for desired repetitions.
