Give me a specific exercise routine that is the most efficient for optimal muscle growth.

For optimal muscle growth, Andrew Huberman suggests a structured and balanced approach that incorporates both strength and endurance elements, while focusing on metabolic stress through shorter rest periods and varied intensity.

Key Components of an Effective Routine:

1. Duration and Frequency:

   • Workouts should last about 45 to 60 minutes to maintain hormonal balance. Training longer can increase cortisol levels, which may be detrimental 1.
   • Aim to train at least five days per week, with a typical schedule incorporating three days focused on strength and hypertrophy, and two days on endurance 2.

2. Intensity and Volume:

   • Allocate about 80% of resistance training to exercises that do not reach failure, with the remaining 20% pushing to failure to promote hypertrophy 2.
   • Perform 10 to 20 sets per muscle group weekly, adjusting based on individual efficiency and recovery capability 3.

3. Exercise Selection and Rep Cadence:

   • Include exercises that both stretch and contract muscles in their full range for comprehensive development 4.
   • Optimize muscle hypertrophy by balancing different rep cadences and varying rest periods (e.g., shorter rest for metabolic stress) 5.

4. Rest and Recovery:

   • Rest days are crucial; taking two days off per week enhances recovery and performance 1.
   • Ensure muscles recover between sessions to prevent overtraining and maximize growth 6.

This approach grounds itself in scientific data and takes into account hormonal impacts, recovery, and physiological adaptations, aiming for sustained muscle growth and overall fitness improvement.
