Want to give yourself a stress induced heart attack?
I started out in the 70s, and kept pushing until I reached the glorious number you see above. But my heart is still beating like it wants to jump out of my chest. And I'm sweating! I've had to resort to the in-the-nose-out-the-mouth breathing technique to try and calm myself down.
Since my heart rate was up, does that count as exercise?
Anyone want to try for 100 with me?
