Good ab workouts?

Question

What are some good ways to work my abs. upper and lower

Answer 1

Sit on a stability ball instead of a chair.
Pelvic thrusts. Crunchs. Side crunches. Canoe (legs up, head up-lay as flat as you can go). Cardio workout when you raise knees up to your chest--opposite elbow to knee. do that 100 times. Hold a pushup position for 30 seconds.

Hope these help. Write if you have any questions on how to do them properly
