Not very well, can you explain it to me? how I apply this in my trainings?
It applies to just about everything really, so don't worry about it's effectiveness.
You've probably already seen it all before though, in the APK WOD or such.
Anyways, the preferable way to do it is to sprint for 400m, a full 400m, then rest about 5 minutes (Less if you can handle it.) then repeating for a total of four times. It increase your anaerobic and aerobic capabilities.
