Fitness & Exercise
The basics of training the body well, without the fad-diet noise.
Strength Training
A form of exercise where the actual strength gains don't happen during the workout itself — they happen afterward, while your muscles rest and repair.
Cardio Basics
An entire category of exercise whose main job description is simply: make the heart work hard enough, often enough, that it gets better at its actual job.
Stretching and Flexibility
Touching your toes is optional; understanding what stretching can and cannot do for you is not.
Yoga
Yoga began in India as a spiritual and philosophical system, and the poses were only one piece of it.
HIIT (High-Intensity Interval Training)
HIIT's best-known recipe, Tabata, came out of 1990s Olympic speed skater training and now serves gym-goers short on time.
Recovery & Rest
The gym session isn't where the progress happens: recovery is, and sleep is its single most important tool.
