The leg tucked PowerBlock crunch strengthens the abdominals and obliques. The dumbbell makes flexion of the spine more difficult, therefore increasing the difficulty of this strength training exercise. Depending on your workout plan goals - choose a lighter dumbbell for muscular endurance or a heavier one for muscular strength. The leg-tucked position decreases the hip flexor involvement.
