Quick but challenging for this busy mom! Love!!

I love the fact that I can listen to my music and do my workout with just my phone and I don’t have to look at it. Just listen. So efficient! I am a fulltime mom and work fulltime! I love my family, and job and so that doesn’t make much time for quality workouts to take care of myself. I believe if you don’t use what you have, you’ll lose it and I am talking physical! I can’t stop my age, but I don’t have to feel my age! Great app!!!


So Far So Good

I’ve had this app on my phone for a few weeks, but never got around to using it. This morning I woke up and said something has to change so I opened the app and took a crack at the 10 min HIIT. Let’s just say that I’m currently sitting on the floor hot, shiny, and breathing heavy as I write this review. Excited to see changes that should occur if I stick to this daily.


Pretty good

I’ve only been trying it for a couple of days, but it seems to be a great system for aerobics, I’m having to catch my breath at the end of 4 minutes when running a mile wouldn’t do much to me. I imagine as I get better the exercise will level with me (faster pushups, whatever) looking forward to being in good enough shape to try he longer workouts.
