The workout that ClassPass deems 2019's trendiest? It's a doozy

Have you ever strapped yourself to a spring-loaded machine and then felt a core sorer than you've ever known?

Then chances are you've tried the workout that ClassPass deems 2019's trendiest: the Megaformer class.

Fitness booking app ClassPass analyzed more than 100 million workouts to determine that the Megaformer workout was the fastest-growing fitness trend in America. The machine-based class, which has been popularized by celebrities including Sofia Vergara, combines pilates with cardio by way of a contraption designed by (or inspired by the design of) trainer Sebastien Lagree of Lagree Fitness. The machine has platforms on the front and back, and a gliding carriage in the middle that forces users to engage stabilizing stomach and leg muscles. And to sweat, often profusely.

Though versions of the machine have been around since 2005, the 30-60 minute Megaformer class has caught on this year, according to ClassPass. The app reports a million Megaformer classes were booked in 2019, which marks a 38.6% increase in Megaformer reservations compared to 2018.

Meanwhile, Lagree Fitness is coming out with a new version of exercise equipment this week: the Megaformer EVO.

Here's what else ClassPass shared in its report: (and here are their 2018 findings, in case you missed them)

The most-booked workout class category in the U.S. is ... strength training. But yoga came in second, and is the class category that first-time ClassPass users were most likely to book in 2019.

The biggest rest day is ... Jan 1. However, ClassPass reports a spike in new-user downloads on Jan. 2. A day-delayed start on New Year's resolutions, perhaps?

The class time most often booked is ... 5:30 p.m. However, 10 a.m. was the busiest class time on weekends.
