20 Fitness Accessories Under $25 to Supercharge Your Workout
Late-night infomercials may have made an ab roller (about $12) seem like a gimmick, but it really does provide a good workout. If used improperly, however, it can lead to back injuries, so be sure to have an experienced user demonstrate proper form or watch an instructional video on YouTube.
The latest smartwatches have built-in heart-rate monitors, but they also cost several hundred dollars. "Dumb" heart-rate monitors (with no internet connection) start at less than $25. They make it possible for the wearer to target a heart-rate zone while exercising, helping optimize aerobic fitness.
Wearable weights ($10 to $25) can make almost any activity, from walking to grabbing a cup of coffee, into a moderate workout. They can also play an essential role in developing muscles during physical therapy.
