The Star Trac Pro Recumbent 6400 exercise cycle is built for comfort, whether you're looking for a short intensive workout or a long endurance building session. The adjustable seat provides excellent lumbar support and remains comfortable even at the end of a long workout. The exercise cycle's armrests provide further support and help to alleviate tension in the shoulder area during a prolonged exercise routine. The reading station even adjusts for maximum comfort. The recumbent cycle's internal belts require no lubrication, so the smooth and quiet performance of the 6400 should require little maintenance. The exercise cycle features heart rate monitors in the handlebars as well as a Polar wireless strap, so resistance levels can be automatically adjusted to maintain a consistent heart rate level. The user-friendly readout makes it easy to select one of the exercise cycle's 11 different workout programs and monitor your progress. The Star Trac Pro Recumbent 6400 is priced at the higher end of home exercise cycles but is a well constructed, feature rich and extremely comfortable machine.
