- MB Situps x 20 (use 6 lb. medicine ball)
- Bicycle Abs x 20 (each time your R elbow touches your L knee = 1 rep)
- Prone Stabilization = 2:00 (count as 20 reps)
- Russian Twist x 20 (use 6 lb. medicine ball)
- Kneeling Roll-outs x 20
NB: if your in better shape - repeat circuit x 2 with no rest and if your more of a beginner try this circuit for <10 reps each and rest in between sets...and slowly increase your volume over time. Keep in mind there are many variations (progressions) that can be used with regard to these exercises. This is just a starting point.
