Content great, few bugs to work out

I am a few days into using the app and the content is really great and I am getting an awesome workout each time. I love that you can make each set as hard or easy as you want and for the majority of the sets you can go at a pace comfortable to you. Some things that would make the app better strictly technologically speaking are things like starting your workout and having an optional automatic mode that after a certain amount of elapsed time will automatically move onto the next workout (maybe a small countdown area on each set). I find it just a little inconvenient to have to go over to the app every time and click to move onto the next workout. I’ve had some issues moving out of the app to change a song and the workout restarting on me, not a big deal to me because I can easily click through to get back to where I was but might be for others. I’ve also had trouble within the profile settings - being able to add in information and save it or go back to the setting page from there. The back arrow and check mark to save what I’ve input has a bug and is super high up so you can’t actually click either button. Excited for more content to be added and would love a section dedicated to legs, we are all striving for those Carrie Underwood / Kacey Musgraves gams.

Day 30 and loving it!

I enjoy working out but have always been extremely self conscious about training in a group setting and this app allows me to workout from the comfort of my own home with minimal equipment. Love that Erin takes you through each step of your workout with highly motivating and fun commentary, talking you through proper form and most of all providing you with the positive words that encourage you to never quit! Love that during my workout I never have to remember what is coming next and it methodically takes you through your circuits or tabatas. The community aspect and posting allows for a positive and supportive environment. Only suggestion is I wish that the community factor allowed notifications to you when someone respond to comments or likes them to create more communication between the community. To my knowledge app is unable to notify me if another participant is commenting on a post. I’d also love to see some incorporation of workouts to some of Erin’s workout play lists. Erin makes working out a game with fantastic results...you are having so much fun you forget how many pushups or squats you’ve actually done! Thank you Erin for sharing your positive enthusiasm for being healthy and for an awesome app that continues to get better every time I use it!

Amazing app for even the extreme beginner!

This app is truly amazing! Erin makes working out fun and her humor thrown in makes it even more delightful (“Don’t forget to smile”). My fitness level is extreme extreme extreme beginner! During day 1 I felt like I was going to die just trying to complete the warm-ups. It took me a little longer and I definitely had to use the modifications on the app but I was able to power through it. I just completed Day 5 and I can already feel an increase in my energy level throughout the day and my flexibility. Once I’ve completed the days workout I feel like I’ve accomplished a huge feat and my motivation level for other tasks of life increases too! I am tired and sore in muscles that I didn’t even know existed! But it’s a good tired and sore. I LOVE the ease of the app. Turn on Erin’s playlist and press start for the day...that’s all the prep work needed. The circuits are not repetitive and each day has been something completely new. I wake up looking forward to the days exercise which is something I never thought I would say! Thank you so much Erin!
