I usually find some way to get my adrenaline pumped up while I'm driving. Usually I'll drive the Jeep nice to piss someone off, have them try and pass me, then let that 5.2 L sing and not let them past me. Everyone around here is always in such a hurry and is weaving through traffic. Occasionally I'll get lucky and stop at a light next to them afterwards and get to have some words with them. It definitely gets my adrenaline up for the gym. I'm sure if I keep doing it it'll start not having the same effect on me, but for now, it works.
