What Health & Fitness tools can do for you
2 tools listed
The health and fitness tools turn body data and habits into numbers. Calculate BMI from height and weight, estimate body fat and basal metabolic rate (BMR), and work out BMR and TDEE to forecast the time and pace to a target weight.
For training, estimate calories burned by activity using METs, find heart rate zones from age and resting heart rate, estimate your one-rep max from weight and repetitions, convert running pace to 5K, 10K, half marathon and marathon times and use an interval timer.
For sleep and daily habits, plan bedtime and wake time around 90-minute sleep cycles, track sleep debt, estimate how long alcohol takes to clear, check recommended water intake and set a reminder timer for medication intervals. All numbers are general guides and are not medical advice.

- ✓ Set a diet or muscle gain target from BMR and TDEE
