Key Function
Strong shoulders keep your upper body relaxed, work with the arms to propel you forward, and help you breathe efficiently. "Proper spinal alignment optimizes the function of the lungs and diaphragm," says Pilates instructor Rebekah Rotstein.
Quick Fixes
Planks: Rest on elbows and hold for 20 to 60 seconds, five to 10 times.
Side Planks: Balance on forearm, hold 20 to 60 seconds, five times each side.
More: To run your best, you need to eat a little differently than the rest of the population. Here's what should be on your plate.
