Sitting on a bench with hands braced at your sides shrinks the leg raise into its most approachable form: the torso is supported, the range is short, and there is nothing to hang from. Treat it as the rung below the flat bench and hanging versions, and progress by pausing at the top rather than adding speed.
How to do the Seated Leg Raise
- Sit on a flat bench with your back straight and your feet flat on the ground.
- Place your hands on the sides of the bench for support.
- Keeping your legs straight, slowly raise them up in front of you until they are parallel to the ground.
- Pause for a moment at the top, then slowly lower your legs back down to the starting position.
- Repeat for the desired number of repetitions.
Tip: Exhale and tuck the pelvis at the top of every rep before lowering slowly.
Muscles worked
Primary
Abs · Core
The lower abs work to tilt the pelvis backward and lift the hips, and you should feel the contraction low in the stomach only once the pelvis starts to curl.
Secondary
- Hip Flexors — The hip flexors lift the legs during the first half of the movement and will do all the work if the pelvis never tilts.
Common mistakes
- Swinging the legs — if the body rocks on a hanging leg raise, you are using momentum; slow the tempo and let the legs come to a dead stop at the bottom.
- Only lifting the legs — the abs do not work until the pelvis tilts up; think of curling the hips toward the ribs, not just raising the feet.
- Lower back arching — if the lower back lifts off the floor, the range is too long; bend the knees or shorten it until the back stays flat.
- Neck straining forward — keep the head neutral on lying raises and hang relaxed from the shoulders on the bar.
Where it fits in a workout
Leg raises go at the end of a session with the rest of the core work, or between sets of an upper body lift. Superset them with ab rollouts or crunches for a full ab circuit.
How many sets, how heavy and how hard: see what the ACSM position stands support.
