Well it depends on how hard and how long you run. Sprinting is one of the best muscle building activities you can do.

I thought it was crazy to try, but I swear it's added 50lbs to my deadlift with one sprint work out a week for 3 months.

Going from 475 to 525 is a pretty incredible increase in my deadlift considering I was adding about 5lbs a month before.
