Best Health Challenges in 2025: Find Your Fit for Lasting Wellness

Explore the best health challenges in 2025—from full-on grit with 75 Hard to gentle habit-builders like 75 Soft, Operation 66, and the 30 Flirty Challenge. Discover the right fitness reset for your lifestyle, goals, and well-being.

Choose a Challenge That Matches Your Goals—And Your Life

In 2025, the most effective health challenges aren’t about extremes—they’re about sustainability, flexibility, and long-term habit change. The best health challenges in 2025 offer more than just a reset—they support your mental and physical wellness. Whether you're seeking structure, strength, or self-care, there's a challenge that fits.

• Pick a challenge that encourages consistency, not perfection
  
  
• The most lasting routines come from flexible, habit-forming approaches
  

1. 75 Hard

A tough mental toughness challenge created by Andy Frisella. Participants must complete six tasks daily for 75 days straight: two 45-minute workouts (one outdoors), follow a strict diet, drink a gallon of water, read nonfiction, and take progress photos. Missing any task means starting over. While transformative, experts warn of risks like burnout and potential injury. 

• Builds accountability and discipline—or pushes too far
  
  
• High risk of strain without enough recovery or support
  

2. 75 Soft

A gentler, more manageable version of 75 Hard. Key rules include one 45-minute workout daily with a weekly active rest day, drinking three liters of water, following a balanced diet (with some leeway), and reading 10 pages daily. Missed days don’t force a reset—making this challenge more sustainable for many. 

• Emphasizes grace and flexibility while still building healthy habits
  
  
• Less chance of burnout, more alignment with life’s demands
  

3. Operation 66

This newer 66-day challenge focuses on habit formation—based on the idea that this is the average time to make something automatic. Rules include morning hydration, screen-free hours, 45–60 minutes of exercise, 30–60 minutes dedicated to a hobby or goal, 10 minutes of stretching, and a 90/10 focus on whole, unprocessed foods. It’s intentional, sustainable, and stress-free. 

• Offers a diverse wellness framework, not just fitness
  
  
• Allows flexibility without “failing” the challenge if you miss a day
  

4. 30 Flirty Challenge

A 30-day, customizable wellness reboot that slashes rigidity. Instead of a fixed regimen, participants pick daily habits across physical (movement, hydration), mental (reading, journaling), and emotional (gratitude, nature time) categories—creating a routine that aligns with how they want to feel. No penalties for off-days; it's about curiosity and sustainable self-care. 

• Where self-compassion and flexibility meet wellness
  
  
• Encourages personal discovery over perfectionism
  

5. Soft Fitness / 75 Soft Inspiration

A growing trend that prioritizes enjoyable, gentle movement over intensity. Soft fitness includes activities like soft hiking, CircusFit, trampolining, or simply walking. It promotes movement tied to pleasure—not just performance—and emphasizes self-care and longevity over “no pain, no gain.

• Makes fitness joyful—and easier to stick to
  
  
• Reduces injury risk while improving physical and mental health
  

Quick Recap

• 75 Hard: Extreme physical and mental resilience
  
  
• 75 Soft: Scalable habit-building with less pressure
