Leg Drop Pulse
- Intermediate
- Isolation
- Rep-based
- Waist
The Leg Drop Pulse is a core-intensive exercise that targets the lower abdominals and hip flexors while engaging the quadriceps through isometric tension. It combines a controlled eccentric lowering phase with a high-tension pulse at the bottom to maximize time under tension.

Setup
- Lie flat on your back on a mat with your arms by your sides or hands tucked slightly under your glutes for lower back support.
- Extend both legs straight up toward the ceiling, creating a 90-degree angle at the hips.
- Engage your core by pressing your lower back firmly into the floor to eliminate any gap.
How to do it
- Inhale as you slowly lower your straight legs toward the floor, stopping just before your lower back begins to arch.
- At the bottom of the movement (6-12 inches off the ground), perform a small, controlled 2-3 inch pulse upward and downward.
- Exhale as you lift your legs back to the starting vertical position using your lower abdominals.
- Maintain a controlled tempo: 3 seconds to lower, 1 second for the pulse, and 2 seconds to return to the top.
Form checklist
- Keep the lower back glued to the floor throughout the entire movement.
- Lock your knees and point your toes to keep the quadriceps fully engaged.
- Keep the pulse small and rhythmic; avoid using momentum or swinging the legs.
- Ensure your neck and shoulders remain relaxed on the mat to avoid strain.
Pro tips
- Focus on the 'hollow body' sensation by pulling your navel toward your spine to protect the lumbar region.
- Squeeze your inner thighs together throughout the set to increase stability and quad activation.
- Pause for a split second at the very bottom of the drop before starting the pulse to eliminate momentum.
Make it harder
- Perform the exercise with your head and shoulder blades lifted off the mat in a 'crunch' position to engage the upper abs.
- Increase the number of pulses at the bottom to 3-5 reps before returning to the starting position.
Frequently asked
- What muscles does the leg drop pulse work?
- The leg drop pulse primarily targets the abs, and also works the hip flexors as secondary muscles.
- What equipment do you need for the leg drop pulse?
- The leg drop pulse requires no equipment — just your body weight.
- Is the leg drop pulse good for beginners?
- The leg drop pulse is rated intermediate. Build a base with simpler variations first, then progress to it with light load and strict form.
