If you MUST do an hour of cardio

...do what I did. You'll be sure to get a major sweat on and if your a cardio machine lover, your going to be excited about this.
Here's what I did today, try it and do yourself a favor. NEVER go back to your skinny fat treadmill running routine again! ;) If you dont have a jump rope, running in place with high knees is just as good!

Step 1:
Treadmill 20 minutes total
2 minute uphill FAST walking
2 minute no incline run as fast as you can!
1 minute step of the treadmill and do 10 burpes
Repeat 3 more times

Step 2:
10 minutes jump roping
50 seconds on, 10 second rest
Repeat 9 more times

Step 3:
Stair Master 20 minutes total
2 minutes climb as fast as you can without hanging on!
2 minutes slow skip a step kick backs for a butt burn
1 minute slow rest to give your legs a quick break
Repeat 3 more times

Step 4:
Jump rope 50 skips
5 burpees
Jump rope 50 skips
4 burpees..... etc to 1 burpee

Sweat literally burning my eyeballs.... successful workout.
