What You'll Learn

The 75 Hard Challenge is a 75-day program with strict rules
The 75 Hard Challenge is an intense 75-day program that requires participants to follow a strict set of rules involving diet, exercise, reading, and self-improvement. It was launched by Andy Frisella in 2019 and has since gained popularity, especially on social media platforms like TikTok.
The program emphasizes "mental toughness" and aims to push individuals beyond their comfort zones to achieve long-term improvements in their minds, bodies, and overall outlook on life. It is important to note that this challenge is not just about physical transformation but also about developing the mental fortitude to deal with life's challenges.
The rules of the 75 Hard Challenge are as follows:
- Two 45-minute workouts per day, with one of them being outdoors. This high-frequency exercise regimen can be challenging, especially for those new to physical fitness or with mobility issues. It is important to be cautious and consult a doctor before starting this or any other exercise program to ensure safety and avoid injury.
- Adhering to a chosen diet without any cheat meals. Participants can pick their diet but must strictly follow it for the duration of the challenge.
- Reading 10 pages of a self-help or educational book daily.
- Drinking a gallon of water every day.
- Taking a progress picture each day.
If a participant fails to complete all five rules in a day, they must start the entire 75-day program over again. This "all or nothing" approach is a key feature of the challenge, emphasizing commitment and consistency.
While the 75 Hard Challenge promotes positive goals related to exercise, nutrition, and mental activity, it is important to consider its intensity and potential risks. The lack of rest days and extremely rigorous exercise requirements may not align with general health guidelines and could lead to burnout or injury.
For those seeking a less intense alternative, Frisella also created the 75 Soft program, which offers a more flexible approach. It encourages participants to eat well, exercise for 45 minutes daily with one day of active recovery, drink 3 liters of water daily, and read 10 pages of any book each day. This version may be a safer way to work towards similar goals while still challenging oneself to adopt healthier habits.

It involves diet, exercise, reading and self-improvement
The 75 Hard Challenge is a 75-day program that involves five daily rules: diet, exercise, reading, and self-improvement. While the challenge is not directly associated with muscle mass loss, the extreme nature of the program and its potential impact on overall health have raised concerns among health professionals.
Diet
The 75 Hard Challenge allows participants to choose any diet or nutritional plan, with the stipulation that they must stick to it rigidly for the entire 75 days. Some popular diets that participants may choose from include the Mediterranean diet, Keto, Vegan, Flexitarian, and Paleo. While these diets can be healthy and promote weight loss, they may not provide adequate nutrients if not properly managed. Malnutrition or inadequate protein intake is a risk factor for muscle loss, particularly in older adults. Therefore, it is crucial to ensure that the chosen diet provides sufficient protein and other essential nutrients to support muscle health.
Exercise
The challenge requires participants to exercise twice a day for 75 days without rest. While regular exercise is essential for muscle health, over-exercising without proper recovery can lead to muscle fatigue and strain, potentially hindering muscle growth and repair. Additionally, the challenge's intense exercise regimen may not be suitable for everyone, especially those with physical limitations or health conditions.
Reading and Self-Improvement
The reading aspect of the challenge may contribute to self-improvement by encouraging participants to seek knowledge and personal growth. However, the challenge's strict rules and potential time commitment may limit the time available for other self-improvement activities. While the challenge emphasizes discipline and consistency, it is important to note that muscle growth and self-improvement are complex processes that require a holistic approach, including adequate rest and recovery.
In summary, while the 75 Hard Challenge involves diet, exercise, reading, and self-improvement, it is important to approach it with caution. The challenge's extreme nature may not suit everyone, and its potential impact on overall health and muscle mass should be carefully considered. Consulting with a healthcare professional or accredited exercise specialist before embarking on such a rigorous program is highly recommended.

Participants must exercise twice a day
The 75 Hard Challenge is a 75-day program that involves a strict set of five daily rules: exercising twice a day, sticking to a rigid nutrition plan, and strengthening mental fortitude. The exercise aspect of the program is expected to be performed twice a day, every day, for 75 days, without rest days.
The exercise component of the 75 Hard Challenge can be beneficial for building muscle mass. Exercise, in general, is an effective way to prevent and reverse muscle loss. Progressive resistance training, in particular, is a recommended way to build muscle mass. This type of training involves gradually increasing the volume, weight, reps, and sets of workouts as strength and endurance improve. The constant challenge can help build muscle and prevent plateaus. Resistance exercises like sit-ups, push-ups, and using resistance bands can also help manage and reverse muscle loss.
However, it is important to note that the 75 Hard Challenge's exercise component may not be suitable for everyone. The program's intensity and lack of rest days may be too rigorous for some individuals, potentially leading to overtraining or increased risk of injury. Additionally, combining the exercise regimen with a restrictive diet, as suggested in the 75 Hard Challenge, may impact an individual's ability to perform the exercises effectively and recover adequately.
To optimize muscle growth and recovery, it is crucial to consume a balanced diet with adequate protein and carbohydrates. A well-rounded diet that provides the body with the necessary nutrients to support muscle growth and repair is essential. It is recommended to consume a meal or drink with a carbohydrate-to-protein ratio of about 3-to-1 or 4-to-1 within 30 minutes after working out. For example, chocolate milk provides about 22 grams of carbohydrates and 8 grams of protein, supporting muscle recovery and growth.
In conclusion, while the 75 Hard Challenge's exercise component of twice-daily workouts can be beneficial for building muscle mass, it is important to approach the program with caution. Combining it with a rigid nutrition plan, as suggested in the challenge, may impact an individual's ability to recover and perform optimally. It is crucial to prioritize adequate nutrition, progressive resistance training, and rest to optimize muscle growth and prevent injury.

It has a rigid nutrition plan
The 75 Hard Challenge is a strict 75-day lifestyle program that involves following various rules, including a 75 Hard diet plan, twice-a-day workouts, and more. The challenge was created by Andy Frisella in 2019 and is described as a 'transformative mental toughness program'.
The 75 Hard Challenge has five main pillars: nutrition, movement, self-evolution, hydration, and mental discipline. One significant element of the challenge is the 75 Hard diet—a meal plan that's totally up to you, as long as you stick to it for 75 days straight. This means no cheat meals or alcohol. If you stray from your chosen nutritional plan, you have to start the 75 days over again from day one.
The 75 Hard Challenge does not provide a specific meal plan. However, it does offer a list of diets that participants can choose from, including the Mediterranean diet, Keto, Vegan, Flexitarian, Paleo, Pegan, DASH, and Whole30. These diets vary in their specifics, but all emphasize the importance of healthy, whole foods and adequate nutrition.
- Breakfast: Scrambled eggs with spinach and feta cheese, a slice of whole-grain toast, and a serving of Greek yogurt with berries
- Mid-morning Snack: A protein shake or a handful of nuts
- Lunch: Grilled chicken salad with mixed greens, cherry tomatoes, cucumber, olives, and a vinaigrette dressing
- Afternoon Snack: Hummus with carrot and cucumber sticks
- Dinner: Pan-seared salmon, quinoa, and steamed broccoli, with a side salad of mixed greens
- Evening Snack (if needed): Cottage cheese with a sprinkle of chia seeds and a drizzle of honey
This meal plan includes a variety of whole foods and nutrient-dense meals to support the rigorous workout regimen of the 75 Hard Challenge. It is important to note that this is just a sample, and individuals should adjust their meal plans to suit their specific needs and preferences.

It can be stressful and obsessive
The 75 Hard Challenge is a 75-day program that involves a strict set of five daily rules: exercising twice a day, adhering to a rigid nutrition plan, reading, and self-improvement. It is designed to be challenging, and if even one task is overlooked or left partially completed, participants must restart the 75-day program from Day One.
While the 75 Hard Challenge promotes physical and mental strength, it can also be stressful and obsessive. The program's rigid structure and all-or-nothing approach can induce stress and anxiety in participants, especially those who are already prone to obsessive or perfectionistic tendencies. The constant pressure to complete all tasks perfectly and the fear of having to restart can lead to mental health issues or exacerbate existing ones.
Additionally, the 75 Hard Challenge's intense focus on physical transformation and strict dietary restrictions can contribute to obsessive thoughts and behaviours around food and exercise. Participants may become overly focused on adhering to the rules, developing an unhealthy relationship with food and exercise that prioritises strict adherence over overall well-being. This can lead to orthorexia, an unhealthy obsession with healthy eating, or compulsive exercise behaviours that interfere with daily life.
The challenge's lack of rest days or flexibility can also be a cause for concern. Rest and recovery are essential for both physical and mental health, and the absence of built-in rest days can lead to burnout, overtraining syndrome, and an increased risk of injury. This can be especially detrimental to individuals with a history of disordered eating or exercise addiction, as it may trigger or reinforce unhealthy behaviours.
Furthermore, the one-size-fits-all nature of the 75 Hard Challenge fails to consider individual differences in health, fitness levels, and nutritional needs. This disregard for personalisation can result in participants following inappropriate or unsustainable routines, potentially leading to injury, nutritional deficiencies, or mental health issues.
While the 75 Hard Challenge can be a motivating and transformative experience for some, it is crucial to approach it with caution and consider one's physical and mental health throughout the process. It is important to remember that health and fitness journeys are highly individualised, and what works for one person may not work for another. Seeking guidance from healthcare professionals and making adjustments as needed can help ensure a safe and sustainable journey towards a healthier lifestyle.
