Jack Split Crunches
The V-up that opens the legs wide at the top, the hands reaching forward between them, then closes them on the way down.
How to do it
Setup
On the back, legs long and together, arms stretched past the head.
Steps
- Fold up, lifting the chest and the straight legs together.
- Split the legs wide at the top and reach the hands between them.
- Close the legs and lower both ends slowly.
Common mistakes
Legs opening on the way up: they split only at the top. Knees bending to reach: legs straight; reach only as far as they allow. Dropping back to the floor: lower as slowly as you rose.
Breathing
Exhale on the fold, inhale lowering.
