Cardio trifecta!

Workout #1 of 3Started my cardio workout with 15:00 on the elliptical - 0.78 mi, 46 cal.

Workout #2 of 3
After warming up my legs on the elliptical, I moved to the treadmill for another 15:00 - 1.09 mi, 167 cal
I worked on stamina by increasing the speed:
#1) 0:00 - 5:00
'Jog'/walk - 4.5/4.0 mph - 3:00/2:00
#2) 5:00 - 15:00
'Run'/'jog'/walk - 5.0/4.5/4.0 mph - 1:00/2:00/2:00

Workout #3 of 3
The last 15:00 on the stationary bike! (6.15 mi, 100 cal)
To get my heart rate up, during every 5:00-segment, I rode as hard as I could for 1:00 (125-135 rpm).
