To do Oblique V-Ups, lie on your side, slightly rocked back onto the fleshy part of your glute so that your body is slightly rotated open toward the ceiling. Place your bottom arm out in front of you just below shoulder height and angle your straight legs out a bit out in front of you with one stacked on top of the other.
Keeping your legs together, lift your feet up toward the ceiling as you crunch your upper body up to reach your top arm toward your feet. “V up” on your side, pressing off your bottom arm as you use your abs to lift your legs and reach your top hand toward your toes. Lift your legs up as high as you can as you reach up as high as you can.
Then relax back down, but don’t completely release at the bottom. Keep your legs slightly lifted and only lightly touch your bottom shoulder back down to the ground.
Then lift back up, pushing through your arm on the ground as you use your abs and glutes to lift your legs and reach up toward your feet.
Complete all reps on one side before switching.
