Bust through that elusive PR in a comfortable pair of women's pants. While you're digging deep at the heavy bag or stretching it out during your hot yoga session, you'll be glad you're wearing women's training pants made with sweat-wicking materials to keep you dry and light, as well as women's leggings made with smooth seams that won't chafe. While pounding the pavement, you'll enjoy a pair of running tights that offer a second-skin feel. To maximize blood flow in your legs to help speed up recovery time, look for women's compression tights that offer a snug, muscle-supporting fit. Also, when you decide to put your endurance to the test against Mother Nature, make sure you choose performance fabrics designed to keep you cool in the heat and warm in the bitter cold.
