CardioTwister Review

Bottom Line

The Pitch: "Get fit with a whole new twist."

April 2009. The CardioTwister is a compact stair-stepping machine with handlebars that swivel horizontally. In high-energy TV infomercials, the manufacturer claims that the CardioTwister will help you shed pounds and inches from your waistline by combining an aerobic workout with an included diet plan.

Reviews, however, say that the CardioTwister exercise machine doesn't live up to the hype. The most common complaint is that the machine feels unstable. Numerous owners complain that the CardioTwister makes a clanking sound during use. According to some reviewers, assembly takes far longer than the 15 minutes promised in the instructional manual, and there are reports of broken digital readout devices and loose handlebars. A major consumer magazine tested this product and found that the CardioTwister burns about as many calories as walking on a treadmill at a relatively leisurely pace, but that traditional exercises are better than the CardioTwister at toning muscles. 

  • Burns calories
  • Diet plan is sensible
  • Feels unsteady and jerky
  • Expensive
  • Noisy
  • Customer service complaints
  • Not as effective as traditional exercises
  • Does not collapse for storage

A small number of people who buy the CardioTwister exercise machine say it provides a fun workout, but the majority of owners say that they don't intend to keep the machine. We read numerous complaints that the manufacturer, Tristar, is slow to respond requests to return or replace defective units. In some cases, it takes weeks to receive a return label, and reviewers say it's a hassle to disassemble and repackage the 37-pound metal machine. This 48-inch-tall machine, which is not collapsible, comes with a diet plan and 30-minute workout DVD.

The CardioTwister has been included in testing at Consumer Reports, and we read more than 60 user reviews of it at, where it's an as-seen-on-TV staple. We also found a handful of reviews at and The CardioTwister is also the subject of a discussion among contributors to SparkPeople, a fitness site.

However, in the comments section, the reviewer claims to have tested the machine in person and found it unsatisfactory.
