Have you ever thought that you want to be the doctors companion? Of course you have, if you want to keep up with a time lord, you got to physically keep up with a time lord.
8th Doctor Workout
start off with a slow walk
20 reach toward the sky crunches
Run as high a speed you are comfortable with for 2 minutes
Walk-5 minutes (seriously, you run as fast as you can for two minutes, you wander around London or wherever for 5 minutes explaining to your companion things)
Spin around 10x, you just got your first kiss.
Punch the air 10x (space is going wibbley wobbley)
Run top speed 1 min
uppercuts for a minute
Dance for a few minutes, you saved the world in time for new years, everyone else is partying.
