Best for Fitness & Training: Walden Surfboards FDR

Stand-up paddleboarding improves your balance and boosts core strength. The 12-foot-6 Walden FDR helps you accomplish both of those goals. Although it's slightly tippy at first, once you're under way, the displaced hull provides a stable ride with lots of glide for sustained training runs. [$1,875; waldensurfboards.com]
