What counts as an exercise?

Riley U.
Any form of focused repetition. AN exercise is different from exercise. AN exercise is any moment in which you have premeditated a sequence of actions taken to achieve an end product. Focusing on your your shoulders rotate on a raise is an exercise, using a formula to achieve the answer of a math problem is an exercise. Exercise in fitness to me would be any bout of work in which heart rate is minimum zone 2 for at lease 50% of a 20+ minute effort
