Question

Will adding muscle make me run faster or slow me down?

Answer 1

Adding muscle, especially to your legs, will definitely make you faster even if you get a little heavier in doing so.

Answer 2

muscle will make u faster, if u really add muscle to ur legs, then u will have more power in ur stride which means u will run faster for a longer period of time and a strong upper body makes a strong core for running, hope this helps

Answer 3

It will make you run faster as long as you don't bulk up alot, just  get really strong muscle espicialy in your legs

Answer 4

Adding a little won't hurt, adding a lot will, of course. If you begin lifting go with low weight (like 60 % of your max) and high reps (3 sets of 10). That will help get you stronger and build muscle slowly but won't add too much bulk.

Answer 5

Depends on which events you are doing and how much you are adding. If you are doing sprints/hurdles/long/triple jump it will help. If you are doing distance/marathon it'll slow you down

Answer 6

muscle is heavier than fat, but i think you'll be able to run faster because your muscles are working together to help you run faster....

you know, a muscular person could run faster than a fat person...
