Calculate your target **Water Intake** based on weight and activity, estimate calories expended with the **Calorie Burner**, and use **Target Heart Rate Zones** to keep your cardio in the optimal aerobic or [fat-burning](https://www.watchurdiet.com/fat-burning-learn-how-new-research-can-unlock-your-hidden-potential/) threshold. ### Recommended Reading to Kickstart Your Plan New to tracking?
