Vegans taking on the 75 Hard Challenge can tailor the program to fit their dietary preferences while still achieving their fitness and mental resilience goals. The challenge encourages participants to follow a strict diet, which can easily be adapted to a vegan lifestyle. Meal planning is essential to ensure adequate intake of all necessary nutrients, including protein, iron, and vitamin B12. The challenge also emphasizes daily physical activity, which supports overall health and well-being. The mental toughness aspect of the challenge is particularly relevant for vegans, as it helps build the discipline needed to maintain a strict plant-based diet while pursuing other personal growth goals.
