CrossFit CEO Greg Glassman is the father of one of the fastest-growing movements in fitness, but he just "doesn't get" another segment of it that has surged in recent years: fitness trackers.

During a CNBC Facebook live chat, Glassman was asked to share his thoughts on all of the products that try to moderate people's health, such as Fitbit and Jawbone, and simply responded, "Junk drawer."

"I don't get any of them," he said.

While Glassman is not a fan, the fitness-tracker market is booming. Last year wearable-device vendors shipped 78.1 million units, an increase of 171.6 percent over 2014, according to IDC data.

"There's some incredible technology. It's amazing to have a wearable that knows what workout you're doing and what reps you're doing, but it turns out I know what workout I'm doing and what reps I'm counting, too."

CrossFit has more than 13,000 affiliates worldwide that are trying to change the way people work out.
