Exercise guide

Pulse-Up

  • Intermediate
  • Compound
  • Rep-based
  • Chest
  • Upper legs
  • Waist

The Pulse-Up is a targeted core exercise that isolates the lower abdominals by using a vertical hip lift to challenge stability and strength. It is highly effective for developing deep core control and vertical power without relying on momentum.

Equipment

  • Body weight

Setup

  1. Lie flat on your back with your arms extended by your sides, palms pressing into the floor for stability.
  2. Extend your legs straight up toward the ceiling so they are perpendicular to your torso.
  3. Flex your feet and keep your legs squeezed together with a slight micro-bend in the knees.

How to do it

  1. Exhale as you contract your lower abs to lift your hips straight up off the mat, pushing your heels toward the ceiling.
  2. Avoid swinging your legs toward your head; the movement should be strictly vertical.
  3. Inhale as you slowly lower your hips back to the floor with control.
  4. Maintain a controlled tempo, focusing on a 1-second lift and a 2-second descent.

Form checklist

  • Keep your legs vertical throughout the entire set; do not let them tilt toward your face.
  • Avoid using momentum or 'kicking' your legs to generate lift.
  • Keep your neck and shoulders relaxed and flat on the mat.
  • Ensure your lower back returns to a neutral position on the floor between reps.

Pro tips

  • Focus on the mind-muscle connection by imagining you are trying to leave a footprint on the ceiling.
  • Minimize the use of your arms for leverage to force the abdominals to perform the entire lift.
  • Pause for a fraction of a second at the peak of the lift to maximize muscle fiber recruitment.

Make it harder

  • Perform the movement with your hands crossed over your chest to reduce stability and increase core demand.
  • Incorporate a slow leg lower toward the floor after each pulse to increase the eccentric load on the abdominals.

Frequently asked

What muscles does the pulse-up work?
The pulse-up primarily targets the abs, hip flexors, and obliques, and also works the erector spinae, glutes, and quadriceps as secondary muscles.
What equipment do you need for the pulse-up?
The pulse-up requires no equipment — just your body weight.
Is the pulse-up good for beginners?
The pulse-up is rated intermediate. Build a base with simpler variations first, then progress to it with light load and strict form.
