I had trouble initially with the never ending infinity sign also. I deleted the app off my phone and downloaded it again! Worked like a charm. I am out of shape and these exercises are challenging but Im on day 6 now and I actually enjoy doing them! Love being able to track my progress and feel like Ive actually accomplished something! Love the exercise demonstrations built into the app it saves me a lot of time googling for these exercises. Well worth the couple bucks I have spent and hopefully I will see enough progress to start another 30 days when this one ends. Im currently doing the 30 day bikini body and 30 day jumping jack challenge.
