Increase the weight or intensity slightly while maintaining good form. Increase the number of sets for each exercise to 6, and aim for 4-6 reps in the compound movements.

Week 3: Intensity and Variation

Introduce variations and increase intensity. For example, consider using different grips or stances for exercises like pull-ups, squats, and deadlifts to challenge your muscles differently.

Week 4: Power and Peak Performance

Focus on powerlifting and explosive movements to maximize strength gains. Reduce the number of sets to 3-4 and aim for 2-4 reps in compound exercises. Consider including one or two high-intensity workouts or complex training sessions in this week.

General Guidelines:

• Perform a 5-10 minute warm-up before each workout, including light cardio and dynamic stretching.
• Maintain proper form and technique; prioritize good form over lifting heavier weights.
• Rest for 2-3 minutes between sets and exercises for compound movements.

Remember to maintain proper nutrition, stay hydrated, and get adequate rest for recovery. This professional-level weightlifting plan is designed for those who have a high level of experience and are seeking optimal results. After completing this one-month program, you can consider more advanced routines, periodization, or working with a qualified strength coach for further progression.
