I hate cardio equipment, for the most part I think it’s useless. But, if you must hop on a piece of equipment, try the Cybex ARC trainer. It has a few programs that aren’t too bad. Here is a true butt-kicking workout on the ARC trainer.

Caution, this will drive your HR pretty high, please exercise with caution!!

Hit the Strength button
Enter your weight
Select Level 10
Keep your strides per minutes over 135 for 10 minutes. Regardless of what the program does, always keep your strides over 135.
Enjoy and report back
