I just have to say that since I started exercising (30 minutes a day on my Mtn Bike w/ Resistance) has REALLY paid off! I had been going back and forth between 183 to 187 lbs for the past 3 months. I kept losing & regaining the same 5 lbs! Some of this was due to my eating patterns, but I am now down to 177.5 and I can honestly say I owe it all to exercising (and I'v only been exercising for about 5 weeks). I wish I had known that it would make SUCH A HUGE DIFFERENCE! Just wanted to share.
