I'm a few days into my 20lbs in 10 weeks challenge and so far the results are good. Three pounds lost since I started. I'd love to hit that 20lb mark as soon as possible, but even if I do I will still maintain the same workout routine through the whole 10 weeks. The food journal I'll need to make a commitment to use for at least 3 weeks.
I'm loving my treadmill! I can use it at anytime during the day or night that is convenient. Don't have to drive 10-15 minutes each way to and from the gym. That time is better spent actually on the treadmill. Not only am I using it for true workout time (3.4 - 3.8 mph), I am also using it at a slower pace (1 - 2 mph) while watching tv, making business calls, reading, researching and taking notes. If I had a laptop then I could use that as well. It's been real easy to put a board across the siderails to use as a desk. I have to warn you though - it's much easier to write at 1mph vs 2mph. :o)
