Weighted Straight Leg Toe Touch Crunch

How to do the Weighted Straight Leg Toe Touch Crunch

1. 1Lie flat on your back on the floor or a mat with your legs extended straight up toward the ceiling, perpendicular to your torso.
2. 2Hold a weight plate or dumbbell with both hands, arms extended overhead or resting on your chest — for maximum load, keep the weight extended directly above your chest as you prepare to crunch.
3. 3Press your lower back firmly into the floor and brace your core before initiating any movement.
4. 4Exhale and contract your abdominals, curling your upper back off the floor and reaching the weight upward toward your toes.
5. 5Drive the crunch from your abs — avoid pulling with your neck or jerking the weight to create momentum.
6. 6At the top, aim to bring the weight as close to your feet as your flexibility allows while keeping your legs fully straight and your lower back on the floor.
7. 7Pause briefly at the peak contraction, then slowly lower your upper back back to the floor under control.
8. 8Inhale as you descend and return to the starting position with your arms extended and upper back just touching the mat.
9. 9Repeat for the desired number of reps without losing tension in the abdominals between repetitions.

Form tips

• Keep your legs locked straight throughout — any bend at the knee reduces the stretch on the abdominals and shortens the effective range of motion.
• Hold the weight directly over your chest or slightly beyond rather than resting it on your torso, so the load stays active the entire way up.
• Lead the movement with your sternum reaching toward the ceiling, not with your chin jutting forward — this keeps tension on the abs rather than the neck.
• Control the descent just as deliberately as the ascent — resisting gravity on the way down produces more time under tension and greater strength gains.
• Start with a light plate (2.5–5 kg) to learn the movement pattern before progressing the load.

Common mistakes

• Using momentum by swinging the arms or jerking the weight upward, which shifts the work from the abdominals to the hip flexors and reduces core development.
• Bending the knees during the crunch, which decreases the stretch on the rectus abdominis at the bottom and makes each rep easier than it should be.
• Pulling the head forward with the hands or straining the neck to reach higher, placing stress on the cervical spine rather than loading the abdominals.
• Lifting the lower back off the floor during the crunch, which transitions the movement into a sit-up and recruits the hip flexors instead of isolating the waist.
• Choosing too heavy a load too soon, causing the form to break down — compensations like bent legs, neck strain, and lower-back arching all reduce ab engagement and increase injury risk.
