I had a look at photos of sprinters on Google image search - they are very muscular - including their abs and arms. They have a better looking body than marathon runners who are typically very thin. Appearing muscular including well-defined abs also means a low body fat percentage. It counts as anaerobic exercise as opposed to cardio - as long as it is less than 2 minutes.
I started walking a lot recently and then started short sprints along the way. I am skinny except for a fairly big belly and some man boobs. My aim is to lose that without losing muscle mass.
I think that sprinting can’t really be done in a gym on a machine - well maybe on a rowing machine… otherwise it could be done sprinting from one side of a gym hall to the other and back repeatedly.
When I sprint it is interesting how the wind blows past my ears. It is a lot more enjoyable than using machines or weights. A benefit of sprinting is that I’d be better at running if I was late for something or if there is some kind of emergency or I need to run away from someone.
Any other fans of sprinting?
