How to do the captains chair straight leg raise

  1. Step 1: Sit on the captain's chair with your back against the backrest and your forearms resting on the arm pads.
  2. Step 2: Keep your upper body stable and your back straight.
  3. Step 3: Engage your abs and lift your legs up in front of you, keeping them straight.
  4. Step 4: Continue lifting until your legs are parallel to the ground or as high as you can comfortably go.
  5. Step 5: Pause for a moment at the top, then slowly lower your legs back down to the starting position.
  6. Step 6: Repeat for the desired number of repetitions.

Sets, reps and programming

Suggested sets, reps and rest for the captains chair straight leg raise by training goal
Goal Sets Reps Rest Effort
Strength 3–5 3–6 3–5 min 1–3 reps in reserve
Muscle growth 3–4 6–12 2–3 min 1–2 reps in reserve
Muscular endurance 2–3 12–20 1–2 min 1–3 reps in reserve

Ranges follow the ACSM position stand on progression in resistance training. Muscle grows across a wide range of loads when sets end close to failure (Schoenfeld et al., 2017), longer rests between heavy sets support strength and size (Schoenfeld et al., 2016), and stopping a rep or two short of failure works about as well as training to failure (Grgic et al., 2022). Estimate your working weights with the strength calculators.
