I didn't manage to make it to the gym before taking the boys to rugby yesterday morning.
After I dropped them off, I took the car back home and returned on the tube. The thinking behind this was that as the B team was kicking off at 11am at the club, and the As were following them on the same pitch at half past twelve, I could have a few sneaky pints once the bar opened at noon.
This is how I came to be at Virgin Active on the recline exercise bike later in the afternoon after four pints of Guiness, demonstrating that you can do steady-state cardio after you've had more to drink than would allow you to drive safely.
This, let's be frank, is empirically derived advice that you would be less likely to get from more conventional coach.
