ABS
Balance Trainer Single Leg Crunches
A crunch performed over a BOSU dome with one leg held straight out. Draping your lower back across the dome opens up the range of motion, and the single-leg position plus wobble force the abs to work more than a plain crunch. A neat way to add balance demands to core training.
How to do it
- 1
Lie back with your lower spine centered on the dome, hands resting lightly behind your head.
- 2
Extend one leg out straight and keep the other foot planted.
- 3
Pull the extended-side knee toward your chest as you curl and twist toward it.
- 4
Lower the torso and straighten the leg back to the start.
- 5
Do all reps on one side, then switch and repeat toward the other knee.
- 6
Keep the core braced and don't let your lower back arch excessively.
