Ashley Conrad's Clutch Life: Day 18
Don't skimp on flexibility! To perform optimally, your muscles need to move through every movement as efficiently as possible.
Treat this flexibility workout as you would any other more intense workout. While you're still technically being active, the flexibility workout gives your body a chance to recover more actively. Just as there are days to work and strengthen the muscles to submission, there are days to restore the muscles, reduce stress hormones, and improve range of motion.
