These are the exercise poles with a patented 8" of built-in suspension that provides an upper body workout as you walk. Developed in Sweden, where walking and skiing are national pastimes, the lower section of each pole houses an internal spring—similar to a pogo stick—that compresses when it strikes the ground. As a result, each stride taken with these poles provides 8.8 lbs. of upper body resistance that burns up to 77% more calories than walking alone. Recommended by physical therapists for those recovering from injuries or who experience back problems, the suspension acts like a shock absorber, making them gentler on shoulders and elbows. Walking with these poles works up to 90% of the body’s muscles while enhancing balance, posture, and coordination, and they can also be used for strength, cardio, stretching, and endurance exercises. Made from durable yet lightweight aluminum and plastic with ergonomic rubber grips and a carbide tip. Length adjusts easily from 45"- 61" to accommodate most users. Black. 45" L x 4" W. (1 1/2 lbs.)
