Thundering erections - and more! Here's a simple exercise that can restore a youthful erection, help to create mind-blowing orgasms (solo or with a partner), and even save your life by giving you a healthy prostate. You can flex PC muscles quickly and repeatedly, or clench tight and hold for as long as you can. Kegel exercises strengthen the pubbocoxygennus muscle (PC muscle), a sling of muscle that surrounds your anus and prostate gland. Strengthening - and learning to control - this muscles is THE sex secret. Time-honored Taoist healing techniques refer simply to "tightening the anus." It's not brain surgery, guys.

How to find your PC muscle: start to urinate. Now stop! In mid stream! The muscles that stop the flow of urine (which also pump when you ejaculate) are the muscles to exercise. If you have trouble stopping the flow of urine, you really need these exercises.

Once you've located them, don;t bother exercising them while urinating. You'll just make a mess. Try:

• PC clamps: squeeze and release, over and over. Start with "sets" of twenty; build to a hundred or more (I recently did a single set of 500 during a car trip). Do at least 200 PC clamps a day. Every day! For the rest of your life!

• Long squeeze: hold PC muscle clamped tight for a count of twenty... or as long as you can.

• Stair steps: tighten and loosen in increments.

• PC flutter: tighten the PC muscle as slowly as you possibly can. At some point it will "flutter," and you'll feel energy sparkling up your spine. Concentrate on deep, slow breathing while you do this - great for restoring energy when you're running down!
