Use in comparison with our 1-pound Fat Chunk™ Model (Item #26016) to highlight the differences between muscle and fat. Comes with an informative, two-sided tent card that discusses the multiple benefits of physical activity, including stronger muscles, better posture, weight control, stronger bones, improved blood-sugar control, and reduced blood pressure and cholesterol. 3½" x 3½".
