For the past month I've been doing:
45 Minutes on the treadmill starting at #2 incline at 2.9 speed working up to #11 incline at 3.6 speed (any faster or running is killing my knees, which makes me want to stop)
I then do free weights, and leg and arm machines for another 30-45 minutes. I'm drinking about 6 bottles of water a day (no soda and cut out my hot tea with splenda) Cut out white breads and pasta as well as cheese.
I've lost 6 pounds which I'm happy about. But I'm not sweating nor am I sore, which is making me feel like I'm not doing anything

Am I crazy?
