To perform an oblique v-up, lie on your side with your legs slightly in front of your body. Contract the oblique muscles, and lift your legs off the floor. Pause at the top before slowly lowering your legs back to the ground.
- Lie down on your side
Lie down on your side with your legs stacked one on top of the other. Your legs should be angled slightly in front of your body. The position of your arms can vary; you may cross them on your chest, or you may place one arm behind your head. If needed, place one arm on the floor to balance yourself.
- Lift your legs
Lift your legs off the ground by contracting your oblique muscles. If you are a beginner, you may bend your knees to make this exercise easier. Continue until your legs reach the top of their range of motion, and pause at this top position.
- Lower your legs
Lower your legs down in a controlled motion until they are back in contact with the ground. Repeat for your desired number of repetitions.
- Rotate your position and repeat
Rotate so that you are lying on your other side, and repeat the process.
