Weighted Seated Tuck Crunch on Floor

Seated on the floor leaning back on the hands, a dumbbell held between the feet is drawn in toward the chest and pushed back out.

How to do it

Setup

Seated leaning back on the hands, a dumbbell pinched upright between the feet, legs extended and just off the floor.

Steps

Draw the knees in toward the chest, the bell with them.
Lift the chest to meet the knees.
Push the legs back out without touching down.

Common mistakes

Dropping the bell: squeeze it between the arches, and use a light one. Rocking back onto the elbows: keep the arms straight. Legs crashing to the floor: stop them just above it.

Breathing

Exhale drawing the knees in, inhale extending.
