The most important thing is to keep the energy balance of the human body, so as to have the effect of healthy exercise (scientific slimming and muscle training).
Personal recommendation: GOBE2 diet tracking health bracelet has six functions: energy balance (monitoring calorie value and consumption value of human food intake), monitoring heart rate, water consumption, blood pressure, stress level monitoring and sleep monitoring.
I suggest you go to Baidu. Now this product has come out to the second generation, both in a treasure and an east!
