Description

An exercise where you balance on your hands and knees, then curl one leg towards the ceiling while keeping your knee bent.

How to Do Quadruped Leg Curl

  1. 1
    Setup

    Begin on all fours, positioning your hands directly under your shoulders and your knees under your hips. Ensure your spine is neutral and your core is gently engaged.

  2. 2
    Setup

    Lift one foot off the ground, keeping your knee bent at approximately a 90-degree angle. This is your starting position for the movement.

  3. 3

    Exhale as you slowly curl your heel upwards towards the ceiling, further flexing your knee and actively squeezing your hamstring.

  4. 4

    Continue lifting until your foot is pointing directly at the ceiling or you feel a strong, peak contraction in your hamstring.

  5. 5

    Inhale and slowly lower your leg back down to the starting 90-degree bent-knee position, maintaining control throughout the entire eccentric phase.

  6. 6

    Complete all desired repetitions on one leg before carefully switching to the other side.

Tips

  • Focus on the hamstring contraction: Actively squeeze your hamstring at the top of the movement to maximize muscle engagement, rather than just lifting with momentum.
  • Maintain a stable core: Keep your abdominal muscles braced throughout the exercise to prevent your lower back from arching or sagging, which can reduce hamstring activation and strain your spine.
  • Control the eccentric phase: Slowly lower your leg back to the starting position, resisting gravity. This controlled descent enhances muscle growth and improves overall strength.
  • Keep your hips level: Avoid shifting your weight or tilting your hips during the movement; keep your hips square to the floor to ensure proper muscle isolation.

Common Mistakes

  • ×Arching the lower back: Avoid excessive lumbar extension by actively engaging your core and maintaining a neutral spine throughout the movement.
  • ×Using momentum: Do not swing your leg up quickly; instead, focus on a slow, controlled curl to isolate the hamstrings effectively.
  • ×Not achieving full contraction: Ensure your heel points directly towards the ceiling at the top of the movement to fully shorten the hamstring muscle.
