Equipment

  • Sled machine

Setup

  1. Sit on the machine with your back and head pressed firmly against the padded support.
  2. Place your feet on the platform hip-width apart with toes pointed slightly outward.
  3. Grip the side handles firmly to keep your hips pinned to the seat throughout the set.
  4. Push the platform up to disengage the safety locks and hold the weight with extended legs.

How to do it

  1. Inhale and slowly lower the platform by bending your knees toward your chest, maintaining a controlled 2-3 second tempo.
  2. Lower the weight until your knees are at a 90-degree angle, ensuring your lower back does not round or lift off the pad.
  3. Exhale and drive through your heels to push the platform back up to the starting position.
  4. Stop the ascent just before your knees lock out to keep constant tension on the target muscles.

Form checklist

  • Keep your lower back and glutes glued to the backrest to prevent spinal strain.
  • Ensure your knees track in line with your mid-foot, avoiding any inward collapse.
  • Keep your heels flat on the platform at all times; do not let them lift.
  • Avoid locking your knees out fully at the top of the movement.

Pro tips

  • To emphasize the glutes and hamstrings, place your feet higher on the platform.
  • To maximize quad activation, place your feet lower on the platform while ensuring your heels stay down.
  • Pull yourself into the seat using the handles to create more stability and force production.

Make it harder

  • Perform single-leg presses to eliminate strength imbalances and increase core stability.
  • Add a 2-second pause at the bottom of each rep to remove elastic energy and increase difficulty.
