What kind of exercise requires the use of oxygen to produce energy?

PUSH UP

I think that because you are going to have to be doing also of exercise and that will be have to be using oxygen.

RUNNING I think that running is a good one too because you will be having to be using oxygen to be able to breath and help you keep your pace as well!
