Congrats Karma. I road my mtn. bike around 1,500 miles last year. This year I am finding it harder and harder to find time to get out for a ride. In January my wife and I bought a treadmill. I have been using that thing on average 4-5 days a week. Sometimes a brisk 20-25 minute walk, sometimes a 20 minute run, and sometimes a 45 minute walk. It works great. I work from home (when not at a customer site) and I noticed it is easy to pack on pounds when your desk is 20 feet from your bedroom. A quick 20 minute walk in the morning and another at the end of the work day and it is like I walked to and from work (1 mile+) each way. I have made some changes to my diet and since I weighed myself on Jan. 2, I am down 6 pounds. Not great, but not bad either (avg. 2 pounds/ mth). For me the treadmill has been a great investment.
