When we did the trials for the science expirement, we did these sorts of things, that we would do, by working out, or we did some random sorts of exersices for the expirement. Our breathing changed a lot of things, by, it would take a lot harder effert, by working out, and us doing all of these sorts of random exerscises that we did in class, duriing the expirement. Also by more effert, I mean by doing the exerscieses when we were doing mostly push ups and we were also doing these jumping jacks, and we were jumping like crazy, so that we could see the effects, that what we were doing, to make it harder and a lot harder for us. Also and at last, that we noticed, that the results, could always change no matter what.
