This is a 40 minute abdominal circuit. I also refer to this type of workout as a HIRT routine.
Warm-Up
5 minutes of non-stop kickboxing combinations, jump rope, or calisthenics
Circuit 1
Try to perform this abdominal circuit at least four times in a 5 minute time period without resting between exercises or sets. You should attempt to complete the required reps for each set before moving onto the next exercise. When you finish the last exercise, start at the top again until your time is up.
Once the first 5-minute circuit is up, rest for 2 minutes, then repeat this circuit again.
Gauge your progress by counting the number of circuits you can complete in 5 minutes.
- Windshield wipers (or Russian twist holding a medicine ball if you can’t handle it) – 10 wipes or twists
- Sit-ups with medicine ball on chest – 20 sit ups
- Flutter kicks – 40 total kicks

You should attempt to complete the required reps for each set before moving onto the next exercise. When you finish the last exercise, start at the top again until your time is up.
