INSTITUTIONAL CROSS TRAINERCYBEX has designed an Arc Trainer that is ideally suited to hotels, corporate fitness, & residential housing where the environment is less demanding than a commercial gym. The 425A has the ultimate versatility that the CYBEX Arc Trainer is known for in a smaller footprint.CROSS TRAINERS VS ELLIPTICALSNot all cross trainers are created equal. Cross training refers to working various parts of the body by combining different exercises in a variety of ways. Typically one activity or sport trains certain parts of the body but not others. Cross training aims to eliminate this. Cross trainers are generally non-impact machines – sometimes called "ellipticals” – which refers to a specific motion. All ellipticals are cross trainers but not all cross trainers are ellipticals.
