Praise for The 4 x 4 Diet:

"Erin's approach, like most successful ideas, is simple and realistic. The more you apply her principles of food and exercise, the more success you will have…. She got me back on track after the birth of my son. I saw my strength and stamina increase and watched my body change for the better."
–Jennifer Nettles, actress

"In the wake of all the books selling "magic quick fixes" for health and weight loss, Erin's simple yet effective 4 step nutrition plan has proven to our family that she knows what she is talking about. Her philosophy is simple yet life changing for all who will take her advice. Her nutrition tips, combined with being active (which she has proven to us really can be fun!) is a sure combination for achieving your goal - whether weight loss or just overall better health. And thankfully, her program is not just for young folks and "boot camp" types but for middle agers like Alan and I!"
–Denise Jackson and Alan Jackson, country singer and musician

"I love doing tabatas. They, along with Erin's 4 principals, have worked for me like nothing before. Fitness and nutrition can be fun and easy when you're working with someone like Erin!"
–Leann Womack, award-winning country singer

It’s hard to find time to work out on the road or while promoting a record. Erin taught me how to incorporate fitness and nutrition into my lifestyle. She is super encouraging and really cares about the people she trains. She's more than my trainer. She's a friend.
–Lauren Alaina, singer-songwriter
