Best: Water workouts

Whatever your favorite workout—be it Zumba, spinning, yoga, or jogging—you can now probably do it in a pool near you. And it's not just for show. By getting your sweat on in the water, you eliminate the joint-jolting and tiring impact of many exercises while adding all-over resistance for greater strength and weight-loss gains, according to the Stockholm University College of Physical Education and Sports. Bonus: People who do pool exercises enjoy their workouts more than those who stick to dry land, per research from Baylor University Medical Center.
