The "75 Hard Challenge" is a demanding self-improvement program designed to foster mental toughness and discipline over 75 consecutive days. It typically involves:

Two 45-minute workouts per day, with one being outdoors.

Consuming a strict diet without any cheat meals or alcohol.

Drinking a gallon (3.7 liters) of water daily.

Reading 10 pages of a personal development book.

Taking a daily progress picture.

Avoiding any other non-prescribed activities.

Completing this challenge can boost mental resilience and create positive habits, but it's important to consult with a healthcare professional before embarking on such an intense regimen.
