Weighted Decline Sit-up
The Weighted Decline Sit-up primarily works the Iliopsoas, with secondary activation of the Adductor Brevis, Adductor Longus, Pectineus, Rectus Femoris, Sartorius, Tensor Fasciae Latae and stabilizer support from the External Obliques, Rectus Abdominis. It is a none isolation exercise at intermediate difficulty.
A none isolation pull exercise targeting the Iliopsoas.

Instructions
- Preparation: Sit on apparatus with lower leg secured under padded bar. Hold weight in front of chest (as shown) orbehind neckor use no weight. Execution: Lower body back until hips are almost extended. Raise body by flexing hips until torso is upright. Repeat. Comments: Exercise can be performed without added weight until more resistance is needed. Lower decline to increase resistance. Rectus Abdominis and Obliques onlycontract dynamicallyif actual waist flexion occurs. With no waist flexion, Rectus Abdominis and External Oblique will only act to stabilize pelvis and waist during hip flexion.
