Fitness challenges
Fitness challenges work by removing the morning decision about whether to train. The challenge already decided. 75 Hard adds two workouts a day plus a sobriety rule and resets to day one for any miss. Couch to 5K replaces the question of how to start running with a fixed nine-week schedule. 30 Day Plank Challenge progresses one variable, daily plank time, so you can see progress without tracking anything else. The choice you actually have is whether you want a program that disappears into your routine or one that takes it over.
75 Hard
A 75-day mental toughness program with five non-negotiable daily tasks. Miss any one and you start over from day one.
30-Day Pushup Progression
Thirty days of daily pushups with weekly progression. Builds from where you actually are, not where you wish you were.
Couch to 5K
A nine-week walk-run program that takes a non-runner to a 5K. Works because it removes the part where you try to run too far on day one.
