Overview
The leg-tucked dumbbell crunch strengthens the abdominals and obliques. The dumbbell makes flexion of the spine more difficult, therefore increasing the difficulty of the exercise. Depending on your goals – choose a lighter dumbbell for muscular endurance or a heavier one for muscular strength. The leg-tucked position decreases the hip flexor involvement.
Description
- Lie on your back with your legs tucked up, feet off the floor.
- Hold the dumbbell at your chest, close to the chin.
- Keeping your neck neutral, roll your upper back off the floor.
- Return slowly to the floor.
Mistakes
- Jutting the chin as you crunch up
- Holding the dumbbell too low toward the stomach
