FACT OR MYTH:
Some people’s idea of “rest day” means no activity at all.
The truth is, light cardio and even light lifting can actually speed up muscle recovery and reduce muscle soreness by increasing circulation to the affected area. Call it "Active Rest".
You don’t need to over do it but activity will keep the healing blood flowing and keep the muscle loose. Even stretching or foam rolling will help your muscles heal and recover faster than total inactivity.
Don’t push the muscles to anywhere near muscle failure but engage in some physical activity to keep the blood flowing and the muscle loose.
