1. An exercise for skiers involves sitting against a wall as if you were sitting in a chair, but without a chair. Thighs should be parallel to the floor and the knees should make a 90 degree angle. Try it. What kind of exercise is this? Which muscles are doing most of the work (which ones begin to hurt)?

Which do you think would be easier: 3 minutes of this exercise or 3 minutes of jogging? Explain.

2. Find some old tennis balls or any type of similar object and try juggling two balls with one hand, or three balls with two hands. Explain how muscle sense is involved in juggling.
