About the challenge

  • Each week you will have 3 core workouts & 2 HIIT workouts, which can be completed from home or the gym. If an exercise requires a piece of equipment (for example: a pull up bar) and you do not have access to one, I have also provided an alternative exercise.

  • Whether you are a beginner or highly advanced, this challenge is for you! Exercise modifications are included for all advanced moves & if you are an app subscriber, you can always message me in the app if you need help adjusting anything! You do NOT need to follow the workouts to a T to be eligible for prizes.

  • I will be beside you every step of the way, communicating, answering questions & sharing daily tips, videos & giveaways in our exclusive Facebook community.

"But wait, don’t you say, 'Abs are cooked in the kitchen?'"

It’s true, abs are built in the gym, but revealed in the kitchen. The single most important tool that you need to develop your abs is proper nutrition. This is why, if you become a member of my CPT Fit App, you will also find all my eating tips, healthy recipes, grocery lists, my Nutrition, Macro, Supplement Guides & more. When you approach your diet with the same level of effort & discipline you bring to your workouts, you’ll start to see all your hard work truly pay off!
