Your best resource for HIIT training and fueling
This book will max your fitness while minimizing your most valuable commodity:  time!

Book shelves are filled with diet and fitness books. Many of them describe how to create a healthy lifestyle, but they often assume that you have an ample amount of two things: equipment and time. 
With High Intensity Interval Training, or HIIT, you get more bang from your proverbial gym time buck. You work harder, not longer, and all of the HIIT IT! workouts can be completed with bodyweight and dumbbells alone. They're under 30 minutes, and take advantage of the scientifically proven method for fitness success. 
On top of that, you'll master the HIIT-style of eating. Snacking on satisfying whole foods throughout the day helps transform your body into an efficient, fat-burning machine.

You’ll Learn:

  • How to combine the workouts in the book into a solid fitness plan according to your unique schedule and training preferences
  • Why HIIT training is effective, and how to use it to maximize your workouts. All the workouts are dumbbells and bodyweight only, and monthly full fitness plans are included
  • How to prevent and break plateaus, taking your fitness to the next level
  • How to create filling combinations from your favorite food groups, and make meals in advance to enjoy throughout the week. Omnivore, Paleo, gluten-free and vegan meal plans are included, and are all Registered Dietitian approved

  • "Beyond weight loss, this is my new favorite manual for living a fit life. Teaching yoga as often as I do, it's easy to forget to balance with strength training. This is an amazing resource for strong, effective, and quick workouts, and tips for attaining balanced nutrition. And it's a super fun read. Highly recommended!"

  • After following Gina's journey for years, I'm thrilled to see her realistic approach to health and fitness in a book. She's created an excellent program that is lifestyle based and doesn't require hours in a gym - perfect for someone like me! I adore that she loves food as much as she loves fitness. Her workouts are killer, but easy to follow and effective. I was sold immediately on her banana almond muffins and have been making her breakfast cookie dough cereal for ages. This book is a must have!
