A brief workout

When I was growing up, there were only two types of underwear -- boxers and briefs. The boxers came in plaid and the briefs were white. No other color options. Then came Underoos!! This made underwear fun to wear, with Superman, Batman and other assorted superheroes and cartoons printed on briefs. However, there was an age limit to wearing Underoos and by the time I turned 14 my mom refused to continue to buy them for me. Rats! It was back to boring white Fruit of the Looms.

So you'll understand my excitement when I attended the Andrew Christian fashion show during L.A.'s Fashion Week and saw that underwear is once again fun! My favorites were the policeman and fireman pairs. Unfortunately, not everyone can wear this underwear and make it look good. The models working the runway all had amazing bodies (though a few of their "walks" would have had Miss Jay from A.N.T.M. throw a tizzy!) and it got me thinking: What exercises did they focus on to prepare them to walk down a runway in their skivvies? Following is a list of must-do's that I would put into my own "brief workout."

1. Cardio, cardio, CARDIO!! A muffin top is not the desired look when strutting your stuff in front of hundreds of gay men. Focusing on cardio will guarantee that you burn a ton of calories. The intensity should be high enough that you are drenched in sweat and your heart rate is 75-80 percent of your estimated maximum heart rate. To figure that out use this simple equation: (220 minus your age) times .75. Use the Stairmaster or stepper to focus on the glutes. Do cardio five times a week for a minimum of 40 minutes.

2. Crunches. Do a variety of crunches to make sure those abs pop. Incorporate crunches that twist to work the obliques and leg raises to focus on the lower abdominal muscle fibers. Remember, you can do a million crunches, but if you aren't doing any cardio then you will not be doing much good.

3. Squats. The best exercise to build the legs and the butt! Which, face it, is what we all first notice on a guy in his underwear. Vary the stance -- feet wide apart and turned out will work the inner thighs, while feet close together work the outer thighs. Squatting low will work the glutes more. Make sure to concentrate on form. If you have any knee or back problems, then you might want to use a machine that allows more control.
