Three years ago, ExerHealth Inc., manufacturer of HealthRider and aeROBICRider home exercise machines, had seven employees in Utah. Today, the company has 300 employees in Utah.

It's because of that growth the company broke ground Friday morning on a 162,000 square-foot building at 3000 E. 6350 South that will allow the consolidation of all corporate operations (excluding manufacturing) under one roof. The company currently is located at 1276 S. 500 West.At the center of the building will be a four-story office section with a three-story atrium. Two wings will extend from the center building that will be for offices and parking. The 14-acre site will feature a landscaped park with walking trails along a creek, which runs through the property.

Helen Smith, vice president, said the new building will allow for consolidation of the telemarketing, customer service, commercial and kiosk divisions, which now are housed in three locations. Manufacturing of the machines is done in Phoenix, Ariz., and other Utah locations.

The Boyer Co. is the land developer, the Babcock Design Group designed the building and Okland Construction will be the contractor.

"We have experienced such tremendous growth over the past three years that our space requirements have increased dramatically," said Gary Smith, chairman. Helen Smith said because of the current trend in keeping fit, the future looks promising for the company.

The two machines are based on inventions of Lloyd Lambert. Revenue has grown from $320,000 in 1991 to $100 million in 1994.

The Smiths attribute much of their success to advertising and locating kiosks in 180 shopping malls.

HealthRider is a dual--action aerobic exercise machine that exercises all of the body's large muscle groups at the same time. The aeROBICRider is a less-expensive version of the HealthRider. This year the company will introduce a commercial-use machine for health clubs and a model for children.
