Gym Science: Muscle, Mind, and Fuel
Like Duolingo, but for Gym Science: Muscle, Mind, and Fuel. Tomo turns the whole topic into a game you play five minutes a day, until it actually sticks.
For the part of you with thirty open tabs that never became anything.
24 levels across 3 sections, about 48 minutes end to end, roughly 10 days at five minutes a day. It moves through Tuning the Lift: Biomechanics in Practice, Fuel and Adaptation: Applied Gym Nutrition, and The Lifter's Mind: Psychology and Programming. It assumes you already know the basics.

Key ideas in Gym Science: Muscle, Mind, and Fuel
- Elevating the humerus overhead places the long head of the triceps in a lengthened, high-tension position.
- Changing joint angle alters muscle resting length and shifts leverage along the active length-tension curve.
- Overhead elbow extension loads the long head far more than pressing down with elbows pinned at the ribs.
- Diaphragmatic inhalation expands the lower torso in 360 degrees before muscle contraction.
- Valsalva contraction against a closed glottis pressurizes the abdominal cavity against the spine.
- Tensing the rectus abdominis and obliques locks the pelvis and ribcage into a rigid platform.
- Bands add tension as joint leverages improve toward the top of squats and bench presses.
- Free-weight dumbbell flies lose all pec tension at the top because gravity acts vertically.
- Cables maintain continuous perpendicular resistance across an entire arc of motion.
- External focus on an implement or environment maximizes motor unit recruitment efficiency and force output.
- Internal focus on target muscle contraction increases local EMG activity but reduces peak force and speed.
- Constrained action occurs when overthinking internal muscle mechanics disrupts movement fluidity.
- A multi-second static pause dissipates elastic energy stored in tendons during the eccentric phase.
- Without the stretch reflex assist, active contractile fibers must recruit more motor units to start movement.
- Momentum at the turnaround reduces mechanical tension demand on the target muscle fibers.
- A moment arm is the horizontal distance between the load's line of pull and the joint axis.
You've tried the other tabs
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 Gym Science: Muscle, Mind, and Fuel 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.
