When training pecs should you do 10 sets for upper pecs and 10 sets for lower pecs in one week?

Training the upper and lower pecs with 10 sets each in one week can be effective, but it's essential to consider your overall workout volume and recovery needs. Typically, 10 sets per muscle group per week is a good starting point for hypertrophy, but individual factors like experience level, intensity, and recovery play a significant role. It's also crucial to ensure balanced training and avoid overtraining, so monitoring your body's response and adjusting as needed is key.
