Reps, recovery, and results — put your fitness knowledge to the test
The highest VO2 max ever recorded was 97.5 mL/kg/min — by Norwegian cyclist Oskar Svendsen.
Each round presents 10 randomized multiple-choice questions drawn from a pool of 50, so every playthrough is different. You get instant feedback with explanations after each answer, plus a shareable score at the end.
Put your exercise science knowledge to the test covering VO2 max and cardiovascular fitness, muscle hypertrophy mechanisms, the Big Three powerlifting lifts, HIIT vs steady-state cardio, the afterburn effect (EPOC), CrossFit's global phenomenon, creatine supplementation research, and the science behind the runner's high.
Research suggests training each muscle group at least twice per week for optimal hypertrophy, with sufficient recovery between sessions.
VO2 max measures the maximum rate of oxygen your body can use during exercise. It's one of the best indicators of cardiovascular fitness and endurance capacity.
Both are effective for fat loss. HIIT burns more calories per minute and creates an afterburn effect (EPOC), while steady-state cardio can be sustained longer. The best choice depends on your fitness level and preferences.
