“You call that fast? I drool faster than that!” Watch out for Coach Josey; she’s a real pit bull. 🙂 But why the emphasis on time? Because power = (mass x distance)/time. The less time you in which you do your work, or the more work you do in a time period, the greater the power output. And power also = intensity; and that’s where the results are! If you aren’t increasing your power, you aren’t getting more fit.
