Interval training reduces your physical recovery time – the time it takes for your heart rate to go from its elevated state to normal. The intermittent periods of exercise and rest are meant to speed up this recovery.
We also have a mental recovery time. When we receive bad news, we are instantly filled with emotions. This can elevate our blood pressure, increase our heart rate or cause us to perspire. The time it takes for us to regain our composure is our mental recovery time.
Mental recovery is also a muscle that can be trained.
