I love the ball roll assignment. I did it back at Sheridan College and it was a big "aha" moments for me. Before that assignment I never really thought about a characters center of gravity moving. In life drawing class you're taught to find it in a still pose. This assignment forces you to see it move with the ball and to keep your character balanced in that movement.
And as a bonus it's also a great way to practice "opposing direction" and "overlap" in a characters action.
