Right, now some knee bends. Legs apart! No, more! Good. Now,
down as far as you can. Up. Great! See how far down you can go.
Come on, bend those knees! This is a great exercise for your leg
muscles Jenny! Hard work, isn't it? Now then, when you come up,
stretch up and bend backwards as far as you can. That's good for
your back muscles as well. Excellent! That's right, carry on!
