The app calculates your personal daily calorie allowance matched with the workouts in your plan. The calories are personalised to you and also take into consideration age, weight etc. so make sure these are up to date on your account tab.
With the calories we give, you can aim to either lean down, add some size or maintain the same weight.
If you need a meal plan with tasty, healthy recipes we highly recommend an app called MealPrepPro. In our opinion it's the best meal planning app on the App Store which is why we linked up with them. Tap the Meal Plan button on the My Calories tab to get setup quickly with one.
