Stretch it Out Before Gardening
Try this pectoral stretch for warming up muscles before yard work
Raking, shoveling, deadheading—fall garden tasks tax your upper body, utilizing muscles that may not be accustomed to so much activity. To minimize soreness, Dr. Gladden suggests this pectoral stretch.
Here's how to do it:
Place your forearm on a tree (or on a wall at the corner of your house), elbow bent at 90 degrees and in line with your body. Lean forward and rotate slightly away from your arm until you feel a comfortable stretch in your chest. Hold for 30 seconds, then switch sides and repeat. Do two or three times.
