In addition to what they've mentioned, it's crucial to have a well-rounded workout routine that targets all muscle groups. Don't just focus on one area – make sure you're incorporating exercises for your chest, back, legs, arms, and shoulders to achieve balanced muscle development. Also, consider adding compound exercises like squats, deadlifts, and bench presses into your routine, as these recruit multiple muscle groups and are great for overall strength and mass gains. And don't forget about hydration – staying hydrated is essential for muscle function and recovery. Keep pushing yourself, stay consistent, and you'll start seeing the gains you're after!
