Lying Straight Leg Marches
- Intermediate
- Compound
- Rep-based

This exercise develops core stability and hip flexor strength while challenging the posterior chain to maintain a bridge position. It effectively integrates the anterior and posterior core by requiring glute activation to stabilize the pelvis while the abs control the alternating leg movement.

Setup
- Lie flat on your back with your knees bent and feet flat on the floor, hip-width apart.
- Place your arms straight at your sides with palms down for stability.
- Drive through your heels to lift your hips into a glute bridge, creating a straight line from your shoulders to your knees.
How to do it
- While maintaining the bridge height, exhale and lift one foot off the floor, extending that leg fully until it is straight and parallel to the opposite thigh.
- Inhale as you slowly lower the straight leg back down, placing the foot flat on the floor without letting your hips sag.
- Repeat the movement with the opposite leg, alternating sides in a controlled, rhythmic 'marching' motion.
- Maintain a steady tempo of 2 seconds for the lift and 2 seconds for the return.
Form checklist
- Keep your pelvis level; do not let the hip of the moving leg drop toward the floor.
- Maintain a rib-to-pelvis connection to prevent the lower back from arching excessively.
- Ensure the knee of the moving leg is fully locked out during the extension.
- Keep the glute of the planted leg firmly squeezed throughout each rep.
Pro tips
- Focus on 'pushing the floor away' with the heel of the stationary foot to maximize glute and hamstring tension.
- Imagine a glass of water sitting on your pelvis; your goal is to march without spilling a single drop.
- Minimize the use of your arms for balance to force the core to do more of the stabilizing work.
Make it harder
- Cross your arms over your chest to reduce your base of support and increase the stability demand.
- Add a 2-second pause at the point of full leg extension to increase time under tension for the hip flexors and core.
