It looks like this is the Six-Pack app for legs! This app has been long-awaited! If its like Six-Pack app, it will take you gradually through strengthening all parts of your legs just like a personal trainer. I will be using this app regularly! Thank you Runtastic! After just 3 sessions I was able to bump my maximum spinning intensity from 18 to 20!
