For those focused on weight training, the 75 Hard Challenge provides a structured way to build muscle and improve overall strength. The program's requirement for two daily workouts can be tailored to include a mix of strength training and recovery-focused activities. Nutrition is key in supporting muscle growth, so a diet high in protein and balanced with other essential nutrients is recommended. The challenge's mental toughness aspect helps weight trainers stay disciplined and committed to their goals, even on tough days. The emphasis on consistency over 75 days can lead to significant gains in strength and muscle mass.
