Seated In Out Leg Raise On Floor
Seated In Out Leg Raise On Floor is a bodyweight core drill built around a seated tuck-and-extend pattern on the floor. You start with your hands behind your hips for support, lean back just enough to load the trunk, and move the legs from a tucked position into a longer lever without losing control of the pelvis. The exercise looks simple, but the quality of each rep depends on how well you keep the torso steady while the legs travel in and out.
The main demand falls on the abs, with the hip flexors, obliques, and deep core muscles helping stabilize the trunk and guide the leg path. In anatomy terms, the work centers on the Rectus abdominis, with help from the External obliques, Iliopsoas, and Transversus abdominis. The shoulders and triceps mainly act as supports because your hands stay planted on the floor rather than driving the movement.
Setup matters because it determines whether the set feels controlled or chaotic. Sit tall, place your hands slightly behind your hips, and turn the fingers slightly outward if that feels better on the wrists. Lean back only as far as you can keep the ribs down and the lower back supported. From there, lift the feet so the legs can move without dragging on the floor, and keep the knees together or nearly together to make the line of tension more consistent.
Each repetition should feel like a controlled tuck and extension, not a swing. Pull the knees toward the chest, then extend the legs forward under tension until you reach the longest position you can hold without the torso collapsing. On the way back in, resist the urge to bounce off the floor or rush the return. Breathe in a steady rhythm so the trunk stays braced as the lever changes.
This movement is useful as accessory core work, a warm-up for abdominal bracing, or a lighter finisher when you want the abs to work without a machine or bench. Keep the range honest, stop the set when the lower back starts to arch, and use the floor as feedback. If you have to rock backward or swing the legs to finish reps, the set has gone past its useful range.
Instructions
- Sit on the floor and place your hands behind your hips with your fingers turned slightly outward for support.
- Lean your torso back just enough to load your abs while keeping your chest open and your ribs down.
- Bend your knees and lift your feet off the floor so your lower body can move without resting between reps.
- Draw your knees toward your chest while keeping them together or nearly together.
- Extend both legs forward under control until you reach the longest position you can hold without your lower back arching.
- Pause briefly in the extended position and keep tension through your abs and hip flexors.
- Pull the knees back in slowly instead of swinging the legs or dropping them to the floor.
- Repeat for the planned reps, then lower your feet and sit up only when the set is finished.
Tips & Tricks
- Move your hands a little farther behind you if you need more support, or closer to your hips if you want the drill harder.
- Keep your heels hovering; touching down between reps turns the set into a rest break.
- If your lower back starts to arch, shorten the leg extension before you shorten the torso angle.
- Keep the knees together so the hips do not twist and the ab tension stays centered.
- Think about pulling the ribs toward the pelvis instead of just moving the legs faster.
- Use a soft bend in the knees if straight legs pull too hard on the hip flexors.
- Exhale as the knees come in or as the legs lengthen, then inhale as you reset the tuck.
- Stop the set when you have to rock the torso or kick the legs to complete a rep.
Frequently Asked Questions
What muscles does Seated In Out Leg Raise On Floor work most?
It primarily targets the abs, with the hip flexors, obliques, and deep core muscles helping control the leg path.
Is Seated In Out Leg Raise On Floor good for beginners?
Yes, if the range stays small and controlled. Beginners should keep the knees bent more and use their hands for steady support behind the hips.
How far should I lean back during Seated In Out Leg Raise On Floor?
Lean back only far enough to feel the abs working while you can still keep the ribs down and the lower back supported.
Should my feet touch the floor during Seated In Out Leg Raise On Floor?
No, not if you want to keep tension on the core. The feet should hover through the set, with only brief contact if you need a regression.
Why do I feel Seated In Out Leg Raise On Floor in my hip flexors?
That is normal, but if the hip flexors dominate, reduce the lean-back angle and shorten the extension so the abs can keep control.
What is the most common mistake with Seated In Out Leg Raise On Floor?
The biggest mistake is swinging the legs and letting the torso rock. That usually means the range is too long for the current set.
How can I make Seated In Out Leg Raise On Floor easier?
Keep the knees more bent, place the hands a little farther back, and stop the extension earlier before your low back starts to arch.
Can I do Seated In Out Leg Raise On Floor if my lower back is sensitive?
Only if you can keep a neutral, supported pelvis the whole time. If the back arches or pinches, shorten the range or choose a less demanding core drill.
