Can you guess the movie?

I'm pretty new here and am loving this website. As I was working out last night on the treadmill, I popped in a movie and came across this wonderful chant. Can you guess the movie?

Pick 'em up! Move 'em down!
Pick 'em on up! Move 'em on down!
Ain't no time to celebrate!
You are old and overweight!
Gotta lose a million pounds!
Get your fat butt off the ground!
Reach on down and touch your toes!
How long since you looked at those?
Shape up!
Lose weight!
Get thin!
Gotta win!
Jumping jacks are good for you!
Now your face is turning blue!
Swing your arms around your back!
Give yourself a heart attack!
Gotta train!
In the rain!
In the sun!
In the snow!
Ten below!
Gotta move!
Gotta do!
Gotta crow!

This will be my new chant
