At the top of your Fuel Plan, when you first open Hexis, you'll see your personalized daily calorie, carbohydrate, protein and fat targets.

See also: Live Energy covers how your energy balance is tracked in real time throughout the day, and How We Calculate Your Exercise Energy Expenditure covers exactly how your training data feeds into these targets.

Your targets adjust based on:

Each day's targets also account for your training yesterday - to support recovery - and what's planned tomorrow - to make sure you're fuelled for it. Because of this, planning your workouts in advance helps keep your targets as accurate as possible.

Your targets are built from a variety data points, evidence-based formulas and proprietary prediction algorithms.

Your RMR is the energy your body needs just to keep functioning at rest. Hexis calculates your RMR using established prediction equations based on the biometric details in your profile: your date of birth, biological sex, height, and weight.

Because RMR is a foundation of your energy requirements and targets it's worth checking that your profile details are accurate and up to date - small errors in height, weight, or other biometric data will carry through to every target Hexis calculates for you. If you sync workouts from a connected platform (like Garmin or TrainingPeaks), it's also worth checking that imported sessions have the correct start time, duration, intensity as incomplete or inaccurate workout data may impact your targets.

Yes, if you have your own tested RMR data, e.g from a metabolic cart, you can input these values via the Personalized Nutrition section of your profile in both the mobile Athlete App and web based Athlete Hub. To do this go to More → Personalized Nutrition → Resting Metabolic Rate, select Custom from the dropdown. An RMR field appears below. Enter your value in kcal and hit Save.
