True Fitness TS1 Elliptical Strider is the only elliptical cross trainer that gives users three basic workout choices: combine the upper and lower body action for the ultimate in total body training, grip the central stabilizer bar for a challenging legs-only cardio session, or stand astride the foot pedals and use the upper body arms for a focused, upper body workout. Like all True machines, the True Strider is manufactured with the highest quality standards in the industry. Robotically welded steel frames, sealed bearings and forged steel cranks mean the True Strider will stand up to years of heavy use.
