Keep fit, take exercise, keep fit and you'll be wise
That's it, grow twice your size, whatever you do keep fit
Keep fit, and take the air, don't flit to your armchair
You'll get no medals there, whatever you do keep fit
Punch that bag as if you're punching your opponents head
Skip around it might rebound and knock you out instead
Keep fit, now bend the knees, don't sit be careful please
You'll split your doh, ray, me's, whatever you do keep fit
Keep fit, skip on your toes, that's it, each movement shows
Your bit of muscle grows, whatever you do keep fit
Now skip, an hour or more, don't slip across the floor
Into the pub next door, whatever you do keep fit
Punch that bag as if you're punching, your opponents head
Skip around it might rebound and knock you out instead
Keep fit, you're doing swell, pull up that big dumb bell
Pull up your shorts as well, whatever you do keep fit
Keep fit, dodge in and out, swing lefts and rights about
Each hit a mighty clout, whatever you do keep fit
You call at your girl's flat, just call to have a chat
That's all it stops at that, whatever you do keep fit
Punch that bag as if you're punching, your opponents head
Skip around it might rebound and knock you out instead
No place like bed at all, in case you hear loves call
Your face turn to the wall, whatever you do keep fit
