As I write this, I just finished my first workout in two days. I planned to take Sunday as a rest day but when Monday came around, I listened to my body and knew I needed an extra one.

Rest days are important. They help heal your body from the strain you put it through during your workouts. Sometimes you also need the mental break from working out. Whatever the reason, no one ever lost all their fitness or weight loss from taking a rest day here and there. Could I have forced myself into my gym yesterday? Probably, but that extra day of rest allowed me to tackle the workout today with heavier weights and more energy.
Even an active rest day can be beneficial. Taking a walk or a bike ride, doing yoga or swimming in the pool; these are all great active rest days that allow you to physically and mentally take a break. You can even stretch or foam roll!
What is your favorite rest day activity?
