Can Short-Term Fitness Challenges Lead to Weight Loss?

Since January 2025, an old fitness trend has regained popularity among Gen Z and Millennials: the 75 Hard Challenge. The challenge consists of five daily tasks for 75 consecutive days. Tasks include:
- Following a strict diet with no cheat meals or alcohol
- Completing two 45-minute workouts (one of which must be outdoors)
- Drinking a gallon of water
- Reading 10 pages of a nonfiction book
- Taking a daily progress picture
The challenge can be a great form of self-discipline and have short-term results just in time for summer. Experts say that it can take anywhere from 21 to 90 days to turn these daily tasks into habits. The question remains if such short-term challenges are an effective way to combat the growing issue of obesity in America.
