Lift both legs together, straight and feet together, while keeping the waist controlled against the band. The abs and hip flexors do the work; the point is clean leg raise control, not momentum.
The band should stay under tension as you lift and lower. If the hips tip, the legs jerk, or the return drops, the rep is losing control.
How to set up the band and start position
Lie flat on your back with your legs straight and feet together. Loop the band around the arches of your feet and hold the ends in your hands so it stays secure before you move.
This position should feel stable, with your waist settled and your abs ready to brace. If the band is off-center or one hand gives more than the other, the lift will start uneven and one leg will usually lead.
How to perform the lift
Lift both legs together until they are perpendicular to the floor, then pause briefly at the top. Keep the work in your abs and hip flexors, not in a swing.
Lower with control back to the start, then repeat for the desired number of repetitions.
How the lowering phase should look
The lowering phase is where you keep control, not where you let the band win. After the pause, bring the legs back down smoothly and keep your abs braced so the waist stays flat.
If the descent stays even, the rep finishes cleanly. If it drops, the work shifts out of the abs and the hips start to tip before you return to the floor.
Common form errors
The clearest misses are soft knees and a bend-and-swing finish. Keep the legs straight and the feet together; once the line breaks, the lift stops looking clean.
Watch the band tension. If one foot rises higher, the arches are not sharing the load and the pelvis usually twists with it.
The hips should stay quiet. If the low back pops up or the hips shift, the abs are losing control of the position.
Lower under control. If the legs fall back down, you lose the work on the way down and the rep turns sloppy.
What a good rep feels like
A good rep starts with your abs, not a yank from the band. Your legs rise together, stay straight, and the waist stays still instead of letting the knees bend or one side lead.
At the top, the legs are vertical and the work stays in the front of the hips and abs. The band should feel even, with your hands only keeping it in place.
On the way down, the lower back stays controlled as the legs return slowly. No drop, no snap, no loss of tension.
How Corect judges the movement from video
The app can analyze this movement from a phone video and score its form. It looks for straight legs, feet together with the band around the arches, a controlled lift to a perpendicular top position, and a slow lower back to the starting position.
It can also flag loss of control if the knees bend, the band shifts unevenly, the hips tip, or the lowering turns into a drop.
Frequently asked questions
It differs from bent-knee leg raises because the straight-leg version makes small control errors easier to spot on video, especially as the legs lower. If the band pulls unevenly, the descent turns into a drop, or the movement looks jerky, the rep is losing control.
Band Lying Straight Leg Raise: the movement, step by step

- Place the band around the arches of your feet and hold the ends of the band with your hands.
- Engaging your abs, lift both legs off the ground until they are perpendicular to the floor.
- 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.
Common questions
How do you set up the band lying straight leg raise?
Lie flat on your back with your legs straight and feet together. Loop the band around the arches of your feet and hold the ends in your hands so it stays secure before you move.

A good rep starts with your abs, not a yank from the band. Your legs rise together, stay straight, and the waist stays still, with the work in the front of the hips and abs.
What are the most common form errors?
The clearest misses are soft knees, a bend-and-swing finish, uneven band tension, hips tipping, and letting the legs drop on the way down.
How does Corect judge the movement from video?
Corect looks for straight legs, feet together with the band around the arches, a controlled lift to a perpendicular top position, and a slow lower back to the start. It can also flag bent knees, uneven band tension, hip tipping, and a dropping descent.
The hardest part of fixing any of this is that you cannot see yourself mid-rep. Corect reads your form from a phone video and shows you what actually happened on each rep of your band lying straight leg raise — depth, bar path, where the breakdown starts. Try it free.
