How come none of our large scale creatures have come from this anaerobic stock? [ Obviously, the ones that find oxygen poisonous would find life in the open ocean or on dry land rather tricky. But why did the oxygen suckers manage to make it to a larger scale when those that didn't give a damn about oxygen stayed on the microscopic scales? ] tag:ask.metafilter.com,2009:site.117939 Fri, 27 Mar 2009 20:27:33 -0800 aerobic anaerobic evolution lifejimbutnotasweknowit oxygen twine42 http://ask.metafilter.com/82364/Looking%2Dfor%2Dhighintensity%2Dlowimpact%2Dportable%2Dexercise I want a high intensity, low-impact workout that I can do every single day, indoors, with minimal space requirements. Jumping rope in my apartment lobby is absolutely perfect except that my feet and knees can't do it daily. Fifteen minutes of high-intensity exercise wakes me up in the morning and gives me a boost for the entire day, so I'd like to do it everyday. However, this seems to cause understandable wear and tear on my body. I have limited space and a low-ceiling in my apartment. Cheap, folding exercise bikes appear to break pretty quick if you use them every day. Expensive exercise bikes are too expensive and I wouldn't look forward to moving one when my lease is up.<br> <br> I am considering purchasing one of those mini-exercise bikes that's just pedals and resistance. Then I could use either my feet or my arms.<br> <br> Maybe I just need to condition my feet and knees over time for the jump rope. But, I have flat feet so there may be significant structural issues. I am looking into better shoes and getting a rubberized mat.<br> <br> Maybe there's something super easy that I'm missing. I don't mind a learning curve, so it can be pretty weird as long as it doesn't put undue wear and tear on the body. tag:ask.metafilter.com,2008:site.82364 Wed, 30 Jan 2008 11:45:09 -0800 anaerobic exercise feet intense jump jumping rope zeek321
