10 Best Seated Flat Bench Leg Pull-in Alternatives for Limited-Equipment Training
What can you do instead of Seated Flat Bench Leg Pull-in? Use movements that isolate the lower rectus abdominis and control hip flexion: hanging knee raises, supine reverse crunches, L-sits, single-leg lying tucks, or standing knee drives. Cue: initiate each rep with a posterior pelvic tilt and actively squeeze the lower abs.
Original Exercise: Seated Flat Bench Leg Pull-in
How to Perform Seated Flat Bench Leg Pull-in
- Sit on a bench with the legs stretched out in front of you slightly below parallel and your arms holding on to the sides of the bench. Your torso should be leaning backwards around a 45-degree angle from the bench. This will be your starting position.
- Bring the knees in toward you as you move your torso closer to them at the same time. Breathe out as you perform this movement.
- After a second pause, go back to the starting position as you inhale.
- Repeat for the recommended amount of repetitions.

4. Decline Reverse Crunch
92.6% MatchHow to perform this exercise
- Lie on your back on a decline bench and hold on to the top of the bench with both hands. Don't let your body slip down from this position.
- Hold your legs parallel to the floor using your abs to hold them there while keeping your knees and feet together. Tip: Your legs should be fully extended with a slight bend on the knee. This will be your starting position.
- While exhaling, move your legs towards the torso as you roll your pelvis backwards and you raise your hips off the bench. At the end of this movement your knees will be touching your chest.
- Hold the contraction for a second and move your legs back to the starting position while inhaling.
- Repeat for the recommended amount of repetitions.
5. Arms Overhead Full Sit-up (male)
92.1% MatchHow to perform this exercise
- Lie flat on your back with your knees bent and feet flat on the ground.
- Extend your arms overhead, keeping them straight.
- Engaging your abs, slowly lift your upper body off the ground, curling forward until your torso is upright.
- Pause for a moment at the top, then slowly lower your upper body back down to the starting position.
- Repeat for the desired number of repetitions.
6. Decline Crunch
89.7% MatchHow to perform this exercise
- Lie on a decline bench with your feet secured and your knees bent at a 90-degree angle.
- Place your hands behind your head or across your chest.
- Engage your abs and lift your upper body towards your knees, curling your torso.
- Pause for a moment at the top, then slowly lower your upper body back down to the starting position.
- Repeat for the desired number of repetitions.
7. Crunch (on Stability Ball, Arms Straight)
89.4% MatchHow to perform this exercise
- Sit on the stability ball with your feet flat on the ground and your knees bent at a 90-degree angle.
- Lie back on the ball until your lower back is supported and your upper body is parallel to the floor.
- Place your hands behind your head or cross them over your chest.
- Engage your abs and lift your upper body off the ball, curling your shoulders towards your hips.
- Pause for a moment at the top, then slowly lower your upper body back down to the starting position.
8. Exercise Ball Crunch
89.4% MatchHow to perform this exercise
- Lie on an exercise ball with your lower back curvature pressed against the spherical surface of the ball. Your feet should be bent at the knee and pressed firmly against the floor. The upper torso should be hanging off the top of the ball. The arms should either be kept alongside the body or crossed on top of your chest as these positions avoid neck strains (as opposed to the hands behind the back of the head position).
- Lower your torso into a stretch position keeping the neck stationary at all times. This will be your starting position.
- With the hips stationary, flex the waist by contracting the abdominals and curl the shoulders and trunk upward until you feel a nice contraction on your abdominals. The arms should simply slide up the side of your legs if you have them at the side or just stay on top of your chest if you have them crossed. The lower back should always stay in contact with the ball. Exhale as you perform this movement and hold the contraction for a second.
- As you inhale, go back to the starting position.
- Repeat for the recommended amount of repetitions.
9. Decline Sit-up

Why You Might Need a Seated Flat Bench Leg Pull-in Alternative
You may need a substitute due to bench unavailability, lower-back pain, hip-flexor dominance, or a desire for progression. Seated flat bench pull-ins emphasize lower-ab isolation and hip flexion; substitutes let you alter hip versus spinal contribution and reduce lumbar shear. For example, reverse crunches minimize iliopsoas recruitment by emphasizing posterior pelvic tilt, while hanging knee raises increase range of motion and abdominal stretch. Use alternatives to manage discomfort, target weak segments of the rectus abdominis, or increase time-under-tension without adding hip-flexor strain. Always cue a neutral-to-posterior pelvic tilt to prioritize abdominal contraction over hip flexion.
How to Choose the Right Substitute
Select a substitute based on equipment, pain history, and the muscle activation you want. If you lack a bench but want lower-ab isolation, choose supine reverse crunches and focus on a slow 2-1-2 tempo with a posterior pelvic tilt to emphasize lower rectus abdominis. If you have a pull-up bar and need progression, use hanging knee raises with controlled eccentrics to increase ROM and oblique engagement. For hip-flexor sensitivity, pick exercises that reduce iliopsoas involvement—perform reverse crunches or L-sit holds with toes pointed and ribs drawn down. Prioritize movements where you can maintain neutral lumbar position and cue the pelvis to lead the contraction.
Frequently Asked Questions
What muscles does Seated Flat Bench Leg Pull-in work?
Seated Flat Bench Leg Pull-in primarily targets the lower portion of the rectus abdominis and the transverse abdominis while involving the hip flexors (iliopsoas and rectus femoris). Biomechanically it combines posterior pelvic tilt and hip flexion, so you feel both abdominal contraction and hip flexor engagement.
What is the best bodyweight alternative to Seated Flat Bench Leg Pull-in?
Supine reverse crunch is the best bodyweight alternative to isolate lower abs while limiting hip-flexor dominance. Cue a posterior pelvic tilt and lift by tucking the pelvis rather than pulling with the thighs to maximize rectus abdominis activation.
Can I build muscle without doing Seated Flat Bench Leg Pull-in?
Yes—you can build abdominal muscle with other core-focused movements like hanging knee raises, L-sits, and slow reverse crunches that provide sufficient time under tension. Ensure progressive overload by increasing reps, range of motion, or tempo while maintaining proper pelvic tilt to target the abs.
