For the nearly three-quarters of exercisers who utilize some type of technology during their workout, Life Fitness is offering more freedom to control and customize their workouts on its equipment. Last week the company released LFopen, the fitness equipment industry's first open application programming interface, which allows developers to create applications for exercisers and facility operators that interact with Life Fitness equipment.

"Opening our API enables us to keep doing what we do best - developing first-class exercise equipment - while unleashing new, creative minds to come up with fresh ways to engage and motivate exercisers," said Life Fitness president Chris Clawson in a statement on the company's website. "The Life Fitness open platform products will enable developers and our customers to create fitness solutions specific to their exercisers and will allow for endless possibilities."
