Simple but effective!

This app has a relatively simple design, but Ive found that not having a bunch of extra stuff makes it incredibly easy to use and even more effective. I did pay to see my stats and Im obsessed with going through my numbers and seeing where I improve and what I need to work on. This workout is great, and Ive definitely seen an improvement in my times and endurance, I love it!!
