VARIATIONS
Captain's Chair Leg Raise
This bodyweight movement isolates the abdominal muscles by raising straight legs against gravity while the torso is supported on a vertical knee raise station. The longer lever increases the demand on the abs and hip flexors compared with the bent-knee version.
HOW TO DO IT
- Step onto the platform and press your forearms firmly into the pads.
- Grip the handles and lift your shoulders away from your ears.
- Press your lower back against the backrest and let your legs hang straight down.
- Exhale and raise your straight legs until they are roughly parallel to the floor.
- Pause briefly at the top without letting your torso drift back.
- Inhale and lower your legs with control, stopping before they swing behind you.
COMMON MISTAKES
- Swinging the legs to generate momentum, which is far more tempting with straight legs.
- Letting the legs drop and swing behind the body on the descent.
- Allowing the shoulders to shrug up toward the ears.
- Arching the lower back away from the support pad as the legs rise.
- Bending the knees mid-rep to cheat the top range.
TIPS
- Keep a slight bend in the knees if straight legs cause the lower back to round.
- Think about curling the pelvis up toward the ribs rather than just lifting the thighs.
- Move at a pace you could stop at any point; if you cannot pause mid-rep, the legs are too heavy for the lever.
- Keep the ribs down and the backrest contact constant from start to finish.
SAFETY
- Stop the set if you feel the lower back arching or pinching against the pad.
- Avoid letting the legs swing back hard into the backrest.
- Anyone with hip-flexor or lower-back issues should build up from the knee raise first.
