ABS
Elbow to Knee Crunch
Adding a twist to the crunch brings the obliques into play alongside the abs. Driving your elbow across to the opposite knee makes for a more intense contraction than a straight-ahead crunch.
How to do it
- 1
Lie on your back with knees bent and feet flat, one hand behind your head.
- 2
Lift your shoulders off the floor and rotate so your elbow arcs toward the opposite knee.
- 3
Hold the top position for a moment with your core engaged.
- 4
Lower your torso back down slowly under control.
- 5
Keep working the same side for your reps, then switch.
