At its debut, the application comes with workouts from more than 300 yoga poses, along with eight hand-crafted Freestyle sessions.

The 10-day challenge runs through August 31, featuring a plan specifically designed to snap users out of their fitness slump after a summer of fun.

This release also comes with improved Session summary that recaps user workouts, highlighting minutes completed, calories burned and Moves completed.

The special 10-day program runs through June 22, allowing non-paid users to try out several premium Freestyle Sessions for free.

During this time the company helped users collectively burn 150 million calories, which is nearly 50,000 pounds or the weight of five adult African elephants.

The "Greatist Wherever Workout" session is available for free and includes five new exercises, as well as the return of the Warm-Up and Cool Down Moves.
