Walkvest: As you progress in your exercise and weightloss program, it’s harder to improve as quickly. The Walkvest, made famous recently by actress Valerie Bertinelli, who used it to shed pounds, allows you to add half-pound weights, up to eight pounds, to make your walking or running regimen more challenging ($59.90; walkvest.com).

Goody: If you often have to stop mid-workout to adjust your hair band or clip, what good is it? Goody’s StayPut collection really does just that. Its hair bands ($3.99) have 52 percent more holding power than a regular band, and the quarter-inch and half-inch claws ($3.99 to $4.99) grip probably longer than you can on those barbells (goody.com).
