The Suspender Plank uses an unstable base to intensify core recruitment, forcing the abs, glutes, and obliques to work harder to maintain spinal alignment. It is a premier movement for building functional stability and anti-extension strength.

Setup
- Adjust the suspension straps so the foot cradles are at mid-calf height.
- Place your feet or toes securely into the cradles while facing away from the anchor point.
- Position your forearms on the floor directly under your shoulders, or use a high-plank position with hands flat.
How to do it
- Exhale and lift your knees off the ground, extending your legs until your body forms a straight line from head to heels.
- Squeeze your glutes and brace your midsection aggressively to lock your pelvis in place.
- Maintain a steady, rhythmic breathing pattern while holding the isometric contraction.
- Lower your knees back to the floor with control once the set is complete.
Form checklist
- Avoid letting your lower back arch or your hips sag toward the floor.
- Keep your shoulder blades spread apart (protracted) rather than letting them collapse together.
- Maintain a neutral neck by looking at the floor slightly in front of your hands.
- Keep constant tension on the straps by pushing your heels or toes firmly into the cradles.
Pro tips
- Actively pull your elbows toward your feet to create a 'lat-wrap' effect, significantly increasing core tension.
- Focus on a posterior pelvic tilt—tucking your tailbone—to fully engage the lower abdominals.
Make it harder
- Add a 'Body Saw' movement by rocking your body 2-3 inches backward and forward while holding the plank.
- Transition into a 'Suspension Pike' by driving your hips toward the ceiling while keeping your legs straight.
