Abdominal Workout

Just like training any other muscle group, give yourself a 5-10 minute warm-up before beginning your workout. Use a treadmill, stair-stepper, stationary bike, go for a jog or any other aerobic activity. Perform some light stretching and range of motion exercises to get loose before you begin.

Hanging Leg Raises
3 sets of 20 reps

Hanging Leg Raise (twisting for obliques)
3 sets of 20 reps left side
3 sets of 20 reps right side

Front Cable Crunches With Rope (increase resistance each set)
3 sets of 15 reps

Side Crunches (on floor)
3 sets of 25 left side
3 sets of 25 right side

Decline Sit-Ups
3 sets of 15

If you are only working abdominals, keep the workout to around 30 minutes, 45 minutes max. Keep the workout active and intense with 30-60 seconds rest between sets and 2 minutes between exercises.
