What would really help is if the exercise machines were geared towards interval training.<p>That makes me wonder if I can program my somewhat fancy elliptical. Why don&#x27;t we have a machine that you can program from your phone yet? It has like 20 built in things, none of which are optimal for what I want to do, why can&#x27;t I create a new program with an app and upload it to the machine?!<p>Time to do some research!
