The Peak Week 5 Day Shred

Peak Week 5 Day Shred: Fast, Fun, and Proven Results

Peak Week is one of my most popular group coaching programs, designed to deliver the fastest results in the shortest amount of time. Whether you want to undo holiday indulgence, prep for a special event, or simply hit the reset button, this program works—again and again.

I created Peak Week over 25 years ago, using it as my pre-contest diet for Ms. Olympia and many other shows. Since then, I’ve coached hundreds of people through it with insane results. This program is short, powerful, and effective. You’ll see why so many participants come back multiple times—even though they could repeat it themselves—because the group energy makes it that much fun.

Your Ultimate Short-Term Reset With Long-Term Impact

Bigger, Deeper, and More Impactful Than Ever

Why Peak Week Works

Proven Results Without Gimmicks

Weight loss programs often overpromise and underdeliver—Peak Week is different.

  • Average weight loss: 7–10 lb
  • Record loss: 16 lb (tied)
  • Most participants: 6–9 lb in 5 days

With my hand on my heart, I’ve only seen this diet not work twice—and that was with the same person. This program works because it’s based on old-fashioned nutrition plus my expertise, not gimmicks, products, or extreme methods.

  1. No exercise requirement
  2. No products to buy
  3. No starving, saunas, or fads
  4. Just proven nutrition strategies

Reset Your Body. Reset Your Mind. Reset Your Life.

  5. A monthly “hardcore week” reset

Your Shortest Path to Maximum Results

A Final Word from Joanne Lee Cornish

If you’re looking for a fast, powerful reset that actually works, this is it. Peak Week is not a fad, not a gimmick, and not another diet you’ll forget next month. It’s a strategy I’ve used personally for decades and coached successfully hundreds of times.

As I always say: “When have you ever been good at something you didn’t understand? Never. We cannot wing weight loss. But with the right structure and coaching, we can achieve insane results in record time.”

Let’s make this your strongest reset yet. I can’t wait to work with you.
