It's so important to have a rest day every once and awhile. It's real easy to want to work out and burn calories in some way every single day but, rest days are crucial to a healthy happy life.
Also, enjoy your rest day! Feel your body relaxing and enjoy all the food you're eating that day to replenish your muscles and mind. Without rest days we can become fatigued overworked and sick of our workout routines.
Enjoy your replenishing days!
