What is fitness?

People talk a lot about “fitness”, as do we here at Simplavida. Depending on the context, it can mean one or more of many things, like metabolic fitness, strength, power, aerobics, or balance. The concept of being fit will mean different things to different people, depending on your goals, age, history, and so on. Exercise is by far the best mechanism we have available to us to achieve a longer, healthier, and more capable life. It is free medicine, and nothing else even comes close. But, your concept of fitness may affect your ability to achieve your goals.
