Is it a good idea to work out every day?

It is not a good idea to work out every day. For years, fitness enthusiasts and coaches taught that taking a day off would lead to poorer results, but research shows that a rest day each week actually improves outcomes, as stated in Runners World.

After a particularly grueling workout day, such as a long run, maxing out on bench press or a difficult speed workout, taking a rest day helps the body heal and recover. Rest days helps to drop fatigue, grow strength and replenish glycogen stores, according to Runners World. The fact that the majority of workout injuries are the result of overuse means that working in rest days and cross training days leads to a longer period of sustained training without interruption from injury.
