Biomechanics and Exercise Physiology
Understand how the human body generates force, stabilizes joints, and fuels athletic output. Connect structural anatomy to real-world movement mechanics and cardiorespiratory energy systems.
Like Duolingo, but for Biomechanics and Exercise Physiology. Tomo turns the whole topic into a game you play five minutes a day, until it actually sticks.
26 levels across 3 sections, about 52 minutes end to end, roughly 10 days at five minutes a day. It moves through Force, Levers, and Joint Torque; Musculoskeletal Anatomy in Action; and Bioenergetics and Systemic Adaptation. It assumes you already know the basics.

Key ideas in Biomechanics and Exercise Physiology
- In third-class levers, the muscle effort inserts between the joint fulcrum and the external load
- Third-class levers have a mechanical advantage below 1, requiring high muscle force for light loads
- The anatomical tradeoff maximizes limb tip velocity and angular range of motion for small contractions
- The external moment arm is the horizontal distance from the joint axis to the vertical gravity vector
- With the arm straight down, the weight line passes directly through the shoulder axis (near zero moment arm)
- At 90 degrees abduction, the dumbbell is farthest horizontally from the shoulder, maximizing torque demands
- Long femurs push the pelvis further backward to maintain center of mass over the midfoot
- A more forward-inclined torso increases the horizontal distance between the barbell and the hip joint
- A longer external moment arm demands greater hip extensor torque to lift the identical bar weight
- Placing the bar lower on the back forces more forward torso lean, lengthening the hip moment arm
- Elevating heels allows greater forward knee translation, extending the knee's external moment arm
- Sumo stance brings the hips closer horizontally to the barbell in the sagittal plane, shortening hip moment arm
- A sticking point occurs where external resistive torque exceeds the net internal joint torque capacity
- Just above the chest, the forearm angle and bar path create peak horizontal distance from the shoulder axis
- Muscle torque capacity drops mid-lift due to shifting internal moment arms and sarcomere overlap lengths
- Torque equals the applied load multiplied by the perpendicular distance from the joint axis to the line of force.

Thirty open tabs. Four facts you actually kept.
You watched. You nodded. By Sunday it was gone.
One answer, then back to scrolling.
Eight weeks. You meant to finish. You didn't.
Tomo gives Biomechanics and Exercise Physiology the Duolingo treatment: levels, streaks, and quick quizzes that test what you just learned. That game loop is what the tabs above never had, so it's the one you actually finish.
