Band Jackknife Sit-Up

Secure a resistance band to a bench or other stable object near ground level. Lay down on your back and attach the other end of the band securely around your ankles.

Position your body so that when your legs are extended, there is tension on the band. Lie flat on the ground, legs straight and together, arms extended above your head.

In a controlled movement, contract your abdominal muscles, bending at the hips to raise your legs while simultaneously lifting your torso off the ground and reaching your hands towards your toes. Imagine "folding" at the waist, drawing your upper body and lower body closer together.

Keep your legs straight throughout the movement, and focus on using your core to pull yourself into a "V" shape.

Pause at the top of the sit-up when your hands are as close to your toes as possible without straining.

Slowly lower yourself back down to the starting position, extending your arms back above your head and allowing your legs to lower back down, while maintaining tension on the band.

Repeat for the desired number of reps and sets, ensuring you maintain proper form throughout each repetition to prevent strain or injury.

Make sure to adjust the resistance of the band to match your fitness level and ensure correct form. If the band is too tight, it could make the exercise too difficult or cause poor technique. If it's too loose, you might not effectively challenge your core muscles.
