How have you tested the durability of the UltraFast CrossTrainer?
The UltraFast CrossTrainer ROM machine is a very robust piece of exercise equipment. We performed life cycle testing in accordance with the endurance loading requirements of the standard specification for fitness equipment, ASTM F2276. During the testing the machine was subjected to the equivalent of more than 8000 workouts (~15 years of residential use). During the testing, the UltraFast CrossTrainer experienced no significant issues.
