Keiser

In 1977, brothers Randy and Dennis Keiser formed Keiser Corporation. The corporation came up with a totally new concept for variable resistance using a compressed air (pneumatics) system. In 1978, the Keisers introduced the world to first air-powered, variable-resistance exercise machines for building strength and power.

Today, Keiser offers its air-powered technology in testing equipment, crossover trainers, treadmills, compressors, rear-wheel-drive exercise bikes and a variety of strength and stretching machines for men and women of all ages.

The Keiser Infinity Series Triple Trainer 3030 is a popular item with fitness enthusiasts as it's basically a functional trainer times three. It has all of the benefits of the company's functional trainer in a space saving, triangular-shaped column. This fitness machine can accommodate up to 3 exercisers at the same time. The Triple Trainer has a resistance range of 0- to 106-pounds. The trainer weighs 400-pounds and it operates on a compressor system, which isn't usually included with this product. However Keiser sells compressors to go with most of their fitness equipment.

The Infinity Series Triple Trainer comes with a 10-year warranty for the frame, a 2-year warranty on the cables, pulleys, and bearings, a 1-year warranty on the chrome, and a 90-day guarantee for the paint, upholstery, seat belts, hand grips, rubber and plastic items. This breakdown of warranties can be very confusing for customers, so if you purchase this machine from Keiser please have a copy handy. The Infinity Series Triple Trainer 3030 requires some assembly and usually sells for about $7,000 online.

You can order Keiser items online from the company's website. Keiser also offers online manuals, training videos and technical support for its products, along with various fitness information via its website.
