Avoid exercises that don't provide a significant stimulus for the target muscle, such as deadlifts for isolated muscle growth, as they engage multiple muscle groups and may not be the most effective choice for specific gains.

Addressing specific issues, like right hand technique, is important before moving forward to avoid reinforcing bad habits.

Accuracy is more important than strength in practice; focus on developing precise movements rather than just powerful ones.

It's more important to focus on accuracy rather than strength when practicing guitar techniques.

To build strength in any endeavor, whether in startups or exercise, it's vital to maintain good form and practice effectively to avoid injury and ensure progress.

Generating isolated contractions is key for muscle hypertrophy, while strength training focuses on moving weights as a system.

If you want to grow a specific muscle, choose exercises that directly target that muscle; for example, to build bigger biceps, do variations of bicep curls.

When designing a training split, ensure that the exercises complement each other to maintain high-quality training throughout the workout.

Making your technique modular helps in practicing effectively, allowing you to focus on specific skills needed for a piece. Practicing like Rafael Nadal, who focuses on repetitive drills, helps internalize techniques so that when it's time to perform, you don't have to think about it.
