Too much sugar and too much cake   You'll end up with a belly ache   Take that greasy steak and fries   Slap that fat right on your thighs      Don't be stupid now lose your shape   Start to stretch and muscle ache   Eat you veggies and wholegrain too   Fruits and fibre will nourish you      Take those legs and make them run   When you're fit it's much more fun      Getting in shape is what it's all about   Don't you just feel it's true   Move it all around just like Jane Fonda now   Then there'll be a brand new you      Stuff you eat can poison you   Make you feel real lazy too   Drugs you take make you insane   All they do is burn your brain      One two three four kick'em high   Join a gym or visit the Y   Five six seven eight feeling fine   You can live 'til 99      Getting in shape is what it's all about   Don't you just feel it's true   Move it all around just like Jane Fonda now   Then there'll be a brand new you      Hey my momma's been cooking good   Long time eating the way I should      Getting in shape is what it's all about   Don't you just feel it's true   Move it all around just like Jane Fonda now   Then there'll be a brand new you      Too much sugar and too much cake   You'll end up with a belly ache   Take that greasy steak and fries   Slap that fat right on your thighs
