DAVID KIRSCH IN A NEW YORK MINUTE

Yesterday, you may have seen me demo my Jiggle Test on Live! With Regis and Kelly. For those of you that missed it, here’s how it works:

Too often clients tell me that they’ve maintained their weight on vacations or work trips without ever stepping foot in the gym. Worse, they tell me they’ve done this while maintaining a less-than-stellar nutrition regimen. Because muscle weighs more than fat, all too often these clients have simply gained fat from overeating and simultaneously lost muscle from underexercising. Their weight on the scale may be the same, but they are “skinny fat.”

The best test of your fitness is a body-fat test administered by a professional, which gives you a true barometer of your lean tissue to fat mass percentage. In lieu of that, you can take David Kirsch’s Jiggle Test.

The Jiggle Test is an efficient self-administered test that determines your level of muscle tone.

Stand in front of a mirror and jiggle, shaking your arms, your rear, and your legs.

If everything stays motionless, you’re fit. If your skin is flapping, you’ve been skipping too many  workouts.
