"Strength Training Exercises Dozens of strength training movements can be automatically recognized, and the fitness watch can count your reps and track your rest time between sets.

After your workout, the Zepp App will show you the muscle group you exercised and how long you exercised it for, to help keep your training efficient.

Live Sports Data Broadcast Instead of raising your wrist to check your data during exercise, get live notifications broadcast through the watch's speaker or your Bluetooth headphones for sports data like heart rate and hydration reminders, distance covered, and more."
