I agree with David's suggestions, but I also want to emphasize the importance of rest and recovery. Many people overlook this aspect of muscle building, but it's crucial for allowing your muscles to repair and grow. Make sure you're getting enough sleep each night, ideally 7-9 hours, and take rest days as needed. It's also a good idea to incorporate foam rolling or stretching into your routine to help prevent injury and reduce muscle soreness. Good luck with your muscle-building journey!
