Lying Bench Leg Raise Overview

The lying bench leg raise works your hip flexors. Those are the muscles at the front of your hips. It also works your abs, the muscles on the front of your belly. You need a flat bench. You lie down with your legs hanging off the end. This move builds strong hips and a tight core. Raising your legs makes your hips and belly work hard. The bench lets your legs drop below your body. That gives a bigger range than the floor. It is good for lifters who know basic core moves. Use it on core or leg days.

What Is The Point of the Lying Bench Leg Raise?

The lying bench leg raise builds strong hip flexors and core stability. It targets deep muscles that help with posture and athletic performance.

How To Do The Lying Bench Leg Raise

  1. Lie flat on your back on a bench with your legs hanging off the end from about the knees down. Grip the sides of the bench up by your head for stability.
  2. Set your lower back gently against the bench and brace your core. Take a breath and pull your ribs down so your spine stays supported.
  3. Start with your legs straight and hanging down off the end of the bench. This is your bottom position.
  4. Keeping your legs straight, slowly raise them up until they are about parallel to the floor. Drive the movement from your hip flexors and lower abs, not by swinging.
  5. Take a controlled 2 to 3 second lift on the way up. Keep your legs straight but not locked hard at the knee.
  6. Pause briefly at the top with your legs parallel to the floor. Squeeze your hip flexors and lower abs and keep your grip firm.
  7. Lower your legs back down slowly under control, resisting gravity the whole way. Take 2 to 3 seconds on the descent.
  8. Stop just before your feet reach the bottom of the range or touch the ground, keeping constant tension. Do not let your legs drop and swing.
  9. Keep your grip solid and your core braced throughout. This works well in the 10 to 15 rep range for 3 sets, and you can bend your knees to make it easier.

Lying Bench Leg Raise Form Tips

  1. Keep your legs straight and together.
  2. Press your lower back into the bench.
  3. Grip the bench to keep your body steady.
  4. Move slowly, both up and down.
  5. Raise your legs to about level with the floor.
  6. Pause and squeeze at the top.
  7. Keep tension by not touching the floor at the bottom.
  8. Breathe out as you lift.
  9. Keep your belly tight the whole time.

Common Mistakes to Avoid for the Lying Bench Leg Raise

  1. Swinging your legs up with momentum. Kicking and swinging turns the raise into a swing and takes the hip flexors and abs out of it. Move slowly and deliberately so the target muscles have to lift the legs.
  2. Letting your lower back arch off the bench. When the back arches, the spine takes strain that your core should be handling. Keep your lower back gently supported and your core braced through the whole set.
  3. Dropping your legs fast at the bottom. Letting the legs fall wastes the eccentric and can yank your lower back. Lower under control over 2 to 3 seconds and keep tension the whole way.
  4. Not holding onto the bench firmly. A loose grip lets your torso slide and destabilizes the whole movement. Grip the sides of the bench solidly to anchor your upper body.
  5. Raising the legs too high and rounding the hips off the bench. Pulling the legs way past parallel can round the pelvis up and shift the work in a way you may not want. Stop around parallel to the floor unless you are intentionally training higher.
  6. Bending the knees when you meant to keep them straight. Letting the knees collapse shortens the lever and cheats the difficulty. Keep the legs straight for the full version, or bend them on purpose to scale it down.
  7. Holding your breath the whole set. Locking your breath spikes pressure and leaves you shaky. Brace hard, then exhale as you lift and stay controlled.
  8. Rushing the reps for a number. Fast, sloppy raises miss the tension that builds the hip flexors and abs. Slow every rep down and feel the muscles working.
  9. Using your neck and shoulders to strain upward. Tensing your neck to help does nothing for the lift and can leave you sore up top. Keep your head and neck relaxed and let your hips and core do the work.
  10. Cutting the range short. Barely lifting the legs or not lowering them fully robs the movement of its full effect. Work through a controlled full range from hanging to parallel.
  11. Letting the legs touch down and rest each rep. Resting at the bottom breaks the tension you are trying to keep. Stop just short of the bottom so the muscles stay loaded.

Lying Bench Leg Raise Workout Tips

  1. This move loads your hip flexors and lower abs through a long range because your legs hang off the end of the bench. That extra range at the bottom is what makes it harder than a floor version.
  2. Move slowly and deliberately. The hip flexors and abs grow from controlled tension, not from swinging your legs with momentum.
  3. Keep your lower back gently supported on the bench. A braced core and neutral spine protect your back while the target muscles do the work.
  4. Use a controlled 2 to 3 second lift and lower. Owning both directions keeps constant tension and builds more than a quick up-and-down.
  5. Add a pause at the top with your legs parallel. Holding the contraction for a beat makes the hip flexors and abs work harder.
  6. Grip the bench firmly to anchor yourself. A solid upper-body anchor lets you focus force into lifting your legs cleanly.
  7. Bend your knees to scale it down. If straight legs are too much, a slight knee bend shortens the lever and lets you keep good form while you build strength.
  8. Program it as core and hip-flexor work. It fits well near the end of a session or on a dedicated core day.
  9. Keep constant tension by stopping short of the bottom. Not letting your legs rest each rep keeps the muscles loaded through the set.
  10. Progress by straightening the legs, then slowing the tempo, then adding reps. Small steps in difficulty overload a bodyweight move safely.
  11. Keep your neck and shoulders relaxed. Straining up top wastes energy and can leave you sore in the wrong places.
  12. Breathe with intent. Brace before you lift and exhale on the way up so you can stay tight without going lightheaded.
  13. Balance hip-flexor work with plenty of core and glute work. Strong hip flexors are useful, but you want them balanced by a strong trunk and backside.
  14. Do not chase soreness as proof it worked. Controlled tension and clean reps build the muscles more than next-day ache.
  15. Film from the side to check for swinging. A quick video shows momentum and back arch far better than how the reps feel.
  16. Be consistent. Strong hip flexors and lower abs build over weeks of steady, controlled work, so keep the quality high and keep showing up.
