Bob Harper’s Contour Kettlebells
6. Bob Harper’s Contour Kettlebells ($24.99-$99.99, depending on weight; gofit.net)
Why we like them: Exercising with a kettlebell may be the latest fitness trend, but most are shaped like a mini-bowling ball with a handle attached to them, making them more uncomfortable on your wrists and forearms during certain moves. This kettlebell is ergonomically-designed with grooves that let the weight comfortably rest on your arms as you exercise. We also like the DVD workout that guides even the exercise novice through an easy-to-follow, full-body 30-minute routine.
