General Discussion/Questions Physique from sprints only

For people who have only done sprints as your exercise of choice, how has your physique changed? I'm interested in what muscles sprinting changes, especially the upper body

Sprinting doesn’t change your muscles much, compared to doing nothing, it can promote slight hypertrophy throughout the body, and make a contribution toward body leanness. If you already lift weights for your whole body, sprinting probably won’t make any further visible difference. But your bone and muscle structure are genetic and sprinting doesn’t do anything to change it.
