The truth is, situps and crunches only serve to give you back and neck problems in future. And it still doesn't help define your tummy (if you eat junk and do lots of ab workouts it won't work either, mind you).
Earlier this evening I did my tummy superset which comprises of:
- Stability ball rollouts - you can feel your abs burn with this manoevre (12 reps)
- Cross mountain climbers - total killer for the obliques (12 reps each side)
