TRNR X-Heavy Strength Tube

Want to build great strength without risk of strain? At 17.1 kg maximum rating, the TRNR Strength Tube in Heavy packs a punch and, because the resistance increases exponentially, reaching its peak intensity at the end of the range of motion, it lets you stay well in touch with your own abilities to prevent the dreaded injury.
