Bioelectrical Impedance Analysis is a method to estimate the body’s composition of body fat and muscle mass. It utilizes a weak electric current to flow through the body and measure the resistance of the body. Most of the water in the body is stored in muscle. So, a more muscular person will likely have more body water and lower impedance. This, in turn, will allow the calculation of estimates of body mass, body weight, and body fat.

Heart Rate Variability (HRV) is the variation in the time interval between heartbeats that can be measured in milliseconds. It is influenced by exercise, hormones, stress, and metabolism and is regulated by the autonomic nervous system. When relaxed, heart rate variability should be increased, and when stressed, it is decreased. However, when a person undergoes chronic stress, and the body stays in a sympathetic overtone-fighting state, their heart rate variability can stay low even at rest. Higher HRV is associated with a healthy heart and lifestyle. So, finding out if you have low HRV can motivate you to change your lifestyle.
