The value of a college education is not the learning of many facts but the training of the mind to think.
—Albert Einstein

Homework problems are organized by chapter:

• 1 - First Steps
• 2 - Walking
• 3 - Running
• 4 - Muscle Biology and Force
• 5 - Muscle Architecture and Dynamics
• 6 - Musculoskeletal Geometry
• 7 - Quantifying Movement
• 8 - Inverse Dynamics
• 9 - Muscle Force Optimization
• 10 - Muscle-Driven Simulation
• 11 - Muscle-Driven Walking
• 12 - Muscle-Driven Running
• 13 - Moving Forward

Some problems are designed to be done by hand (✎); others require a computer (💻) or use OpenSim (🏃‍♂️). The amount of time required has been estimated for some problems:

• 🕒 = Less than 15 minutes
• 🕒🕒 = Between 15 and 30 minutes
• 🕒🕒🕒 = More than 30 minutes

Some problems have been grouped into Problem Sets for assigning as homework:
