Getting a Cardio Burn!

This evening at the gym, I decided not to follow the MobileFit workout, and strictly do cardio only.  I noticed in the past that when I up my cardio level, I saw better weight loss.  I like the MobileFit program, but I combines cardio and strength training in the same day.  Honestly after about 2 weeks of following these workouts, I haven't seen much weight loss (although my clothes are fitting better).

I did 3 workouts/routines (two 15:00, and one 20:00) :
* Workout #1 - Stairclimber/stepper: 15:00, 42 floors climbed (0.68 mi), 601 steps, 82 cal 

 * Workout #2 - rower - 2490 m (1.55 mi), 386 cal

(Cal. data not recorded by this machine, and I didn't have heart rate watch this evening.  This is based a online calculator on the MapMyRun website).

 * Workout #3 - Stationary Bike: 20:00, 3.97 mi, 112 cal
C/D - 5:00
TOTAL - 4.84 mi, 134 cal

TOTAL CARDIO: 55:00, 7.07 mi, 602 cal

I really felt good when I was done.  I'll try a few more longer cardio sessions over the next couple of weeks to see if I have different weight loss results.
