Yes. One summer my friends asked me to join in a running program with them. We went from basically sedentary to running 5k a day within several weeks. They hoped to lose weight. I didn't expect to, because we weren't eating any differently, but I did it because I wanted to get stronger and less out-of-breath. I was right; we didn't lose any weight, but we did get much better at running without gasping to a stop within a couple minutes.
