Seriously awesome program. I'm down 9 pounds, but I gained knowledge on really how to eat right. Real talk, I went into this thinking eh, not crazy about fasting, in my opinion a fad…along with other thoughts. However, I was proven wrong. Starting this I was already on a "weight loss journey" after losing 60lbs since Nov 18. I hit a point where I was hitting the gym everyday, but the scale wasn't budging. I knew it was what I was eating. Being consistent at the gym and the proper food intake clicked. Thank you, you rock!


Got my Sweat on with Tommy Cassano


Hey everybody! I did the program last spring & was so pleased with the results I completely changed my eating habits, maintained the weight loss (15lbs) & enjoy eating clean! Most of the time. 3 Joined this time really to keep myself "more" accountable, get rid of this "Covid slump" feeling & catch up with my partners in health! So happy to be back!

Hi all. Looking forward to another Lean 28 session. In response to Tommy's request for posts as to why we joined: I need a reset for clean eating - quarantine has been tough. I have lupus and Tommy's program goes beyond the anti-inflammation diets that I try/want to adhere to. The intermittent fasting also helps with my inflammation. Importantly, the program makes me accountable for daily exercising!


Day 28? Naw…day 1 of the rest of my life. Now 13lbs lighter with more energy, better food choices & invaluable knowledge. Thank you Tracy R for the heads up & thank you Tommy, Beatrice, & everyone on this journey for all the support.

Fitness is hard but nature is the ultimate inspiration. I founded OutdoorBody to share my fitness journey with the world and show how the geographic glory of our National Parks and the boundless beauty of Mother Nature can help you reach your personal fitness and lifestyle goals.


Outdoor Body is the culmination of my life’s work, and the continuation of my life’s journey. It is the launching pad for my life-changing programs, including OutdoorBody, Lean28, Ultimate Man, and other still in development. We provide programs for the body, accountability for the mind, and inspiration for the soul. Fitness is hard. But together, we can accomplish anything. I am living proof my programs work… so I have only one question for you. Are you ready to get your journey started?
