Exercise guide

Lying Frog Kick

  • Beginner
  • Isolation
  • Rep-based
  • Hips
  • Lower legs

The Lying Frog Kick is a highly effective glute isolation exercise that emphasizes the gluteus maximus and medius by combining hip extension with external rotation. It is excellent for improving mind-muscle connection and building gluteal endurance while minimizing lower back involvement.

  • Body weight

Setup

  1. Lie face down on a mat with your forehead resting on your stacked hands to maintain a neutral spine.
  2. Bend your knees to 90 degrees and bring your heels together, pointing your toes outward to form a diamond shape with your legs.
  3. Widen your knees slightly beyond hip-width apart while keeping your heels firmly pressed against each other.

How to do it

  1. Exhale and squeeze your glutes hard to lift your thighs 2-4 inches off the floor while keeping your heels pressed together.
  2. Hold the peak contraction at the top for one second, focusing on the tension in your glutes.
  3. Inhale as you slowly lower your thighs back to the floor with control, maintaining the diamond leg shape.
  4. Perform the movement with a controlled tempo, avoiding the use of momentum or swinging.

Form checklist

  • Keep your heels pressed firmly together throughout the entire set to maintain external rotation.
  • Avoid arching your lower back; the lift should come from hip extension, not lumbar extension.
  • Keep your pelvis pressed into the floor to stabilize your core.
  • Ensure your upper body remains relaxed and your neck stays neutral.

Pro tips

  • Focus on 'scooping' your pelvis into the floor before you lift to maximize gluteal recruitment and protect the spine.
  • Imagine you are trying to push your heels directly toward the ceiling rather than just lifting your knees.

Make it harder

  • Place a light-to-medium resistance loop band just above your knees to increase the demand on the gluteus medius.
  • Incorporate a 3-5 second isometric hold at the top of every repetition to increase time under tension.
