Will the zooms be recorded if I cannot make the live calls?
Yes, the zoom meetings will be all be recorded and loaded into the app within 24 hours.
Will I be able to submit questions for the zoom calls?
Yes, we will have a form we send out after the first onboarding zoom which you can use to submit questions for our expert guests. This will allows us to answer as many questions as possible! We will also share the questions that were answered with the group so you know what is answered if you are watching the zoom recording.
Do you offer a meal plan?
No, this course provides you with the information on how to structure a macronutrient and calorie budget for your specific goal. What you do with your calorie budget is up to you and your individual dietary and nutritional preferences.
Do I need to have MyFitnessPal or another nutrition tracker?
No, and you don’t need to use any nutrition tracker for this course. We will teach you how to calculate a calorie budget for your goals and how to spread your macros across that budget. Join Shred Happens to put all that learning in place where we will support you with demonstrations on the basics of how to use one if you choose to do so during the Shred Challenge.
For how long do I have access to the course materials?
You have access to the course for the lifetime of the Hailey Happens Fitness App.
When are the education modules uploaded?

You have access to the plan for the lifetime of the Hailey Happens Fitness App. The workout plan will include three full-body strength workouts and three cardio workouts (both LISS and HIIT/SIT) each week.
