I am 6 months post partum with my 2nd , I was following Iulias workouts since my 2nd trimester, and absolutely loved them. When I was cleared to start workouts again I decided to give her app a try. I am so so glad that I did! Almost 5 months later and I LOVE the home workouts. I can see actual progression!! (Both physically and mentally) Each workout provides a bit of a challenge and by the end of the workout you are so impressed by what you just accomplished that you look forward to the next.

I love this app, but had to cancel because of financial reasons. Very disappointed that right after canceling it no longer played the videos of the workouts being performed. I can only see what the workouts are through pictures. I still have 3 weeks left of my subscription that I paid for and I'm missing a huge part of what the app is about. I have tried restarting the app, logging in and out of the account, and redownloading. Very frustrated and disappointed.

This is one of the BEST fitness apps in the WORLD it's super easy to follow and I LOVE how the videos play for each exercise, no longer do u have to bounce around and find the video for the exercise ur doing! Great detailed description of each exercise! New exercises each week ! You get multiple home guides and gym guides I love it!! And they are always quick to answer any questions! Unlike other fitness apps who never help you! BEST FIT APP EVER!!!
