The 75 Hard Challenge: A Critical Look at Mental Toughness and Sustainable Habits

Five requirements. Seventy-five days. No breaks and no room for mistakes. That’s the premise of 75 Hard, a challenge created by entrepreneur and author Andy Frisella and marketed as a “transformative mental toughness program” and “an ironman for your brain.” While the challenge has gained popularity, experts caution that its rigid, all-or-nothing approach may undermine the long-term behavioral changes it promises.

What is the 75 Hard Challenge?

The 75 Hard challenge involves adhering to a strict daily checklist for 75 consecutive days. This includes following a structured diet with no alcohol, drinking a gallon of water, reading 10 pages of nonfiction, taking a progress photo, and completing two 45-minute workouts, with one being outdoors. Missing even one task requires restarting the entire challenge from day one.

The Appeal and Potential Pitfalls

Many individuals are drawn to the challenge’s structure, seeking to rebuild discipline and momentum. Chicago runner Sarah Lyons initially found the structure appealing, hoping it would support her overcome feeling “stuck in a rut” both physically and mentally. However, experts warn that this rigidity can backfire.

“Sustainable fitness isn’t about punishment or proving discipline through extremes — it’s about building habits that integrate into your lifestyle in a way that feels supportive and repeatable,” says Dana Santas, a certified strength and conditioning specialist and mind-body coach in professional sports.

The ‘start over’ rule can reinforce a cycle of perceived failure, especially when life inevitably intervenes. This mindset can also negatively impact eating behaviors, potentially contributing to binge eating, disordered eating patterns, negative body image, and negative self-talk, according to Bethany Doerfler, senior clinical research dietitian at Northwestern Medicine Digestive Health Institute in Chicago.

Dietary Flexibility and Realistic Approaches

One element of 75 Hard that allows for some flexibility is the dietary component. Participants choose their own diet, which could include approaches like the Mediterranean diet, Paleo, or a focus on cutting ultraprocessed foods. Experts emphasize that any dietary change is most effective when designed for real life.

Doerfler recommends the Mediterranean diet, emphasizing fruits, vegetables, whole grains, legumes, nuts, plant-based fats, and limiting ultraprocessed foods and desserts. She also suggests strategies like meal prepping and planning for social settings to maintain consistency without undue stress.

Key Takeaways and a More Sustainable Approach

While 75 Hard incorporates healthy habits like daily movement, reading, and hydration, experts suggest focusing on building habits you can maintain when life gets messy. The challenge’s rigid structure can create unnecessary stress and anxiety, potentially hindering long-term success.

Before beginning any new exercise program, it’s important to consult your doctor and stop immediately if you experience pain.
