Muscles worked

Primary

  • Glutes
  • Hamstrings
  • Quadriceps

Secondary

  • Abs
  • Obliques

Equipment

  • Sled machine

Setup

  1. Lie flat on the back pad with your shoulders firmly against the supports and head relaxed.
  2. Place your feet hip-width apart on the platform, ensuring your heels are flat and secure.
  3. Disengage the safety locks using the side handles while keeping the weight supported by your legs.

How to do it

  1. Inhale and slowly lower the platform by bending your knees until they reach approximately a 90-degree angle.
  2. Exhale and drive through your heels to push the platform back up to the starting position.
  3. Maintain a controlled 2-0-2-0 tempo, avoiding a pause at the top or bottom.

Form checklist

  • Keep your lower back pressed firmly against the back pad at all times.
  • Ensure your knees track in line with your toes, avoiding any inward collapse.
  • Stop just short of locking your knees at the top of the movement.
  • Keep your feet flat on the platform throughout the entire range of motion.

Pro tips

  • Focus on driving through the mid-foot and heel to maximize glute and hamstring engagement.
  • Pause for a split second at the bottom of the rep to eliminate momentum and increase time under tension.

Make it harder

  • Perform the movement unilaterally (one leg at a time) to address strength imbalances.
  • Incorporate a 3-second eccentric (lowering) phase to increase metabolic stress.
