The Slastix band is a patented design built to optimize the life of your band, keep you safe from breakage, prevent over-extension, and make it possible for anyone to work out with resistance bands. Slastix stands for "safety sleeve elastic", an original design at the core of everything Stroops does. With Slastix, you get a band that is virtually impossible to over-extend while protected by the sleeve. Safety sleeve elastic technology makes it so users can avoid all the common hassles of resistance band exercise, such as snagging on body and neck hair, and damage such as nicks, cuts, and abrasions to the band. The covered tubing also protects you if you have an allergy to latex. Resistance training should be a part of your exercise routine no matter your goals or your intensity level. With Slastix, build your strength and endurance through exercise of all kinds for every part of your body. Slastix has two built-in clips to hook onto any base, or you can hook it to itself to create a loop, which can get you started on calf, hamstring, and glute exercises. Tightening and loosening your band helps you to progress or regress your exercises. Don't waste any more money on cheap bands built to break just from their intended use; your Slastix band is your long-term go-to resistance band. Bring further customization to your new workout buddy with five resistance options from 10-30 pounds and each with a length of 36 inches.
