After working out a specific muscle group, let it rest for a day or two. This gives your muscles a chance to repair and heal. The other days, train different muscles. Be sure to work the opposing muscles to keep your body balanced.
When you make an active recovery, you help your heart, muscles and nervous system to take a break from intense activity. But don't let your body be inactive. Staying active during the rest day helps your body recover and recharge faster. During active recovery, blood, lymph, and muscles remain active.
Rest day workouts are also known as active recovery, which means that you allow your body to recover from a workout while keeping it moving.
