Act as a Certified Strength and Conditioning Specialist (CSCS). Design a [Number]-day workout split for a [Beginner/Intermediate/Advanced] trainee focusing on [Goal, e.g., Strength, Muscle Growth, Endurance]. Include: 1. Exercise names. 2. Sets and Rep ranges. 3. Rest intervals. 4. RPE (Rate of Perceived Exertion) for each movement. 5. A 'Pro Tip' on form for the most complex lift in the routine. Ensure a balance of compound and isolation movements.

Act as a Hypertrophy Scientist. Optimize my training for maximum muscle growth. 1. Define 'Mechanical Tension' vs. 'Metabolic Stress'. 2. Suggest the ideal 'Weekly Volume' per muscle group for my level. 3. Explain 'Proxy to Failure' and why RPE 8-9 is the sweet spot. 4. Provide a 'Progressive Overload' strategy for the next 4 weeks. 5. Nutrition tips for 'Leaning Bulking'.

Act as a Body Transformation Coach. I want to achieve 'Body Recomposition' (losing fat and gaining muscle simultaneously). 1. Calculate my 'Maintenance Calories' and suggest a slight deficit/surplus. 2. Define the exact 'Protein Threshold' needed for muscle protein synthesis. 3. Design a 'Resistance Training' focused schedule. 4. Explain the role of 'NEAT' (Non-Exercise Activity Thermogenesis) in this process. 5. How to track progress without using the scale.
