Simple 20-Minute Ab Workout for Triathletes

50 Chair-lift Sit-ups

These are great sit-ups for developing the oft-neglected upper abs. Most sit-ups tighten the lower four-pack of muscles, while this type of exercise places more emphasis on the upper four muscles in the abdominal region.

Lying on your back, lift your legs off the ground in a 90-degree angle as if you are sitting in a chair (only the chair is flat on its back). Again, placing your hands behind your head, slowly raise your head straight up toward the ceiling (unlike the previous sets, do not curl your head toward your knees, but rather reach your head up toward the sky, directly above you). If you do this correctly, it will feel different than the previous sit-ups, because you are working a different set of abdominal muscles.

Follow with 15 push-ups.

50 Bicycles


"Bicycles" are not exactly sit-ups, but they work the abdominals just as well, if not better, than traditional stomach curls. It is important to do these correctly, in a slow and controlled repetitive motion, to get the most out of the exercise.

Lying on your back, bring your feet up off the ground as if you are beginning a set of chair-lifts. With your hands behind your head, bring your left elbow toward your right knee and then your right elbow towards your left knee, while constantly moving your legs in a cycling motion.

Rather than a series of repetitive motions like the previous sets of sit-ups, bicycles are a smooth, continuous motion as you cycle your legs while twisting your spine left-to-right, alternating elbows-to-knees.

Count 50 controlled rotations, then relax. Or you can time yourself for a minute, executing the motion slowly and methodically. This is the hardest abdominal drill, which is why it is last in the workout.

End with 15 push-ups.

Upon completion of this dry-land set, your stomach muscles should be burning and an overall tightness in your abdominals will be apparent. When workout time is scarce, this simple set of drills can be done anywhere, anytime. On a hotel room floor in the morning before your shower, or prior to a scheduled workout, for example.

It only takes 20 minutes, but consistently doing this short workout every other day is a great way to strengthen these oft-neglected stomach muscles.

The result will be better form in the pool and a leaner waistline. Who wouldn't want that?
