I sit in the spa for a few minutes at home before getting geared up for my morning commute. I do this rain or shine. Not quite the same as showering but gets me nice and warmed up and woken up. I have a full locker room at work and hit the shower once I arrive.

On occasion I shower before the evening commute home too. Makes it a bit easier to survive a cool commute home if I start off warmed up.
