Sliding Leg Curl On Floor With Towel

  • Intermediate
  • Compound
  • Rep-based
  • Lower legs
  • Waist

This exercise is a highly effective bodyweight movement for isolating the hamstrings while building core and glute stability through a bridge position. It emphasizes the eccentric phase of the leg curl, which is crucial for hamstring strength and injury prevention.

Equipment

  • Body weight

Setup

  1. Lie flat on your back on a smooth floor (hardwood or tile) with your knees bent and feet flat.
  2. Place a small towel or sliders under both heels.
  3. Position your arms by your sides with palms down for stability.
  4. Engage your core and lift your hips into a glute bridge position, creating a straight line from shoulders to knees.

How to do it

  1. While keeping your hips elevated, slowly slide your heels away from your body until your legs are nearly straight.
  2. Inhale during the extension and maintain a controlled 3-4 second tempo.
  3. Exhale as you dig your heels into the floor and pull them back toward your glutes, keeping your hips high throughout the movement.
  4. Squeeze your hamstrings and glutes at the top of the movement before starting the next rep.

Form checklist

  • Keep your hips elevated and level throughout the entire range of motion.
  • Avoid arching your lower back; keep your ribs tucked and core engaged.
  • Ensure your feet stay parallel and do not flare outward.
  • Maintain a slow, controlled speed, especially during the extension (eccentric) phase.

Pro tips

  • Focus on 'digging' your heels into the floor as if you are trying to scrape the ground toward you to maximize hamstring recruitment.
  • Maintain a constant squeeze in your glutes to protect your lower back and keep the tension on the hamstrings.

Make it harder

  • Perform the movement unilaterally (one leg at a time) while keeping the non-working leg tucked toward your chest.
  • Add a 2-second pause at the point of maximum extension before pulling back.
