So, I finally decided it was time to start working out again. My apartment complex has an exercise center that's actually pretty comprehensive. I was surprised, and felt a little sheepish that it's taken me this long to make use of it.
I got on the treadmill, and using my m4d d0ct0r sk1llz, figured out my target heart rate. For those of you that are curious, your maximum heart rate is 220 - age. Ideally, cardiovascular exercise should occur somewhere between 60 and 80% of your maximum heart rate. That's why stress tests aim for 85% maximum, and why a stress test that doesn't achieve at least somewhere close to 80% is worthless.
Anyway, my target HR was between 140 and 160, roughly. Well, I achieved and maintained that HR on the treadmill at the blazing speed of 3.5 MPH. I think the girl running at 7 MPH next to me must've worked pretty hard to contain her laughter. And this is why I don't go to gyms.
