Tuck jumps are brutal. I do them when I haven't been able to sprint (or haven't felt like it) because it's a much faster workout, but very taxing as well. I also do it as a quickie before showering sometimes. You'll feel your quads much more than when you're sprinting, but in no way am I saying it's better than sprinting, just different. I still think hill sprints are king and should be done more often than not.
