Treadmill Training With a Twist

If the snowy, ice-covered streets and sub-zero temps have chased you indoors, I have good news: Group treadmill classes, like the four below, are popping up around town. Whether you’re a runner who wants to stay in shape for the spring or a walker who loses interest after five minutes of mind-numbing treading, these classes will keep you working hard and having fun this winter. — Research by Kelsey Stone and Samantha Gray
