I try to change it up from time to time. I love doing the elliptical, well not really but I get a great workout on it. I am up to 31 min and hoping to get up to 45 min! I also do the kettle bell which I really like. I do the bicycle, the treadmill, strength training. I want to buy a jump rope too! I like to do different things to keep from getting bored and so my body doesn't get used to it! Whatever it is I decide to do that day I try to do at least 30 min!
