Straight Leg Sit-up
Master the straight leg sit-up, a core-strengthening exercise. Keep legs flat and straight to specifically target your abdominal muscles.
Description
A variation of the traditional sit-up where legs remain straight and flat on the floor, targeting the abdominal muscles specifically.
How to Do Straight Leg Sit-up
- 1Setup
Lie supine on the floor with your legs extended straight, feet together, and arms either extended overhead or crossed over your chest.
- 2Setup
Actively engage your core, pressing your lower back into the floor to maintain a neutral spine and prevent arching.
- 3
Exhale as you initiate the movement by contracting your rectus abdominis, rolling your torso up off the floor towards your knees.
- 4
Continue to lift your torso until your chest is close to your thighs, ensuring your legs remain straight and your heels stay grounded.
- 5
Inhale as you slowly and with control reverse the movement, articulating your spine segment by segment back down to the starting position.
Tips
- Control the descent: Avoid flopping back down; control the eccentric phase to maximize muscle engagement and protect your spine.
- Keep legs straight: Actively press your heels into the floor and engage your quadriceps throughout the entire movement to prevent your knees from bending.
- Focus on core engagement: Initiate the movement from your abdominal muscles, not by yanking your neck or using excessive momentum from your arms.
- Vary arm position: Crossing your arms over your chest increases difficulty, while extending them overhead can provide counter-leverage, making the exercise slightly easier.
Common Mistakes
- ×Using momentum: Avoid swinging your arms or yanking your neck to get up; instead, focus on a slow, controlled abdominal contraction to lift your torso.
- ×Lifting heels or bending knees: Keep your heels pressed firmly into the floor and your legs straight throughout the entire movement by engaging your quads and glutes.
- ×Arching the lower back: Do not allow your lower back to arch excessively off the floor during the movement; maintain a slight posterior pelvic tilt by engaging your core.
