Best Fitness App for the Best Price

By far the best workout app - Kelly always makes sure my form is right even though it’s through video!

So good!

Absolutely love Kelly’s classes! As a new mom I don’t always have the time that I used to, to be able to get to a studio for a class. That’s where Kelly’s on demand classes have been so helpful. Not only is she a great instructor but those small movements really get my body burning. Also loved the postpartum ones for when I was first getting back into working out.

Scam

Allows you to do a free trial and then does not let you cancel. Impossible to figure out how to cancel the free trial. So therefore you are automatically charged for the subscription after free trial is up. What a business model.

Kelly’s classes are amazing!!

Kelly’s workouts are the only ones I’ve found that are actually challenging, full body, and incredibly efficient (45 minutes). Not to mention, you also see incredible results! It is a unicorn workout class and I’m completely obsessed!!

The best workout app!!

Love Kelly’s workouts! They also push me to my limits and I feel the gains from a single workout days later. Her pacing, cues, music and coaching make her workouts exceptional. Highly recommend if you’re looking for something super effective but low impact. Can’t recommend enough!
