Standing Row

What it does: Focuses on your back again, and here's why: Those muscles are some of the first to lose strength with age, says Stull, and the more back-focused moves you do, the more you'll be able to prevent or counteract that decline.

How to do it: Using a cable machine with the cables attached at shoulder height (again, if you don't have a cable machine handy, secure a resistance band around some sturdy furniture), face the machine, hold the cable handles and step back a few feet, keeping your feet wider than hip width apart. Squeeze your abs and pull the bands by bringing your shoulder blades together, then pulling with your arms. Return to starting position. Do up to 3 sets of 12 reps.
