Fitbit Charge 5 + Premium connects the dots between your activity, sleep and stress so you can make the best decisions for your body, mind and health. It all starts with your 6-month Premium membership and Daily Readiness, a score based on activity, sleep and heart rate variability (HRV) that helps you optimise your workout routine. Your score comes with personalised activity recommendations: low means go easy and recover-light yoga, deep breathing-while a high score gives you the green light to go all out. Enhance your recovery routine with advanced stress-management tools like the on-wrist EDA sensor. Stay ahead of heart health with atrial fibrillation (AFib) heart rhythm assessments using the on-wrist ECG app. And you'll always have motivation to reach new goals with hundreds of guided workouts, a gallery of refreshing mindfulness sessions plus the fitness features you know and love like Active Zone Minutes and built-in GPS.
