Rotating Decline Sit-Up

The rotating decline sit-up is a trunk and hip flexion exercise that allows greater difficulty through a longer range of motion compared to the sit-up and adds a rotational component to the conventional motion.
Secure your feet in the pads of a decline sit-up bench. Hold your fingers at the sides of your head or across your chest. Crunch the trunk and sit up to bring yourself up as far as possible while rotating one shoulder to the opposite knee. Return to the bottom while maintaining tension in the abs and repeat, rotating to the other knee.
The decline sit-up provides trunk and hip flexion training with resistance farther along in the hip flexion movement relative to a sit-up on the floor, and adds rotation to the motion to develop more aspects of trunk stabilization.
Perform sets of 10-30+ reps; if adding weight, perform sets of 8-15 reps.
Rotating decline sit-ups can be done with additional weight (such as a dumbbell or plate held behind the head/neck), and of course with the sit-up board at different angles.
