Instead of some cleverly crafted prose about training your midsection, how about a comprehensive, slammin’ routine you can do 2–3 times a week for the next six weeks, that will take you from “abs” to “Abs” (provided you keep your diet tight and your sleep on track)? Yeah, I thought you’d like that. Shifting from wordsmith to ironsmith right…now:

Exercise Reps
Crunch 20
Bicycle Crunch 20
Weighted Rotation (Bus Driver) 20
Mountain Climber 20
Plank position, knees outside to elbows 20
Plank 20 secs

Rest 20 seconds and go again. Knock this out 2–4 times a day, 2–3 days a week and you’ll get an “A” in abs.
