Weight training 50:00 
Back at Penn.
Complete workout. Strength is at about 85% of summer peak.
Cross Training 30:00  3.34 mi (8:59 / mi)
614 calories on classic Penn machine.
Bike 30:00  10.4 mi (2:53 / mi)
309 calories. It is very hard to burn a lot of calories on this thing. I maxed out the resistance on each "rest" interval and spun fast on the "hills." I then realized that for calorie purposes it doesn't matter how fast you peddle - the machine thinks it's all the same.
