I appreciate everyone's encouragement!
What adds to the excitement is that I don't do cardio on a regular basis...like NEVER. When I go to the gym, it's all weights, 4 times a week. I really need to keep cardio in my life, so I'm hoping this kicks off a new habit. I'm only 32 with borderline hypertension (138/80) with a family history, so lots of benefits to gain. Thanks again.
