I never thought I could do it, but I did. I had been using the treadmill for > 15 years as an adjunct to my resistance training in the gym; I never really enjoyed plodding on this motorized machine. But since a month ago when my wife lovingly asked me to buy one for her, I find myself using the contraption more than she does. With its imposing presence in our bedroom, we have the freedom to walk/run whenever we want. I run in the morning or late at night- it doesn't really matter as long as I'm running. My wife walks on it while watching her favorite shows and keeping an eye on our one year and 8 month old Vincent busy at play. This day, a month after we got the treadmill, I ran continuously for 49 minutes covering a distance of 5 Km- a personal best so far. I'll continue to run for its health benefits and for the natural high it gives.. what an endorphin release!!!
