Hottest Bodies 2014

Bikini Bodies at Every Age

Age is but a number! See stars in their 20s, 30s, 40s and 50s show off their body confidence in sexy swimwear

HAYDEN PANETTIERE, 23

Exercising is a regular thing for the petite actress, but not everything: "If I push myself too hard, my brain starts thinking of working out as a burden instead of something I enjoy," she tells Self.com. "Three times a week is a really healthy amount."
