Has nobody bothered to ask him what his technique/form looks like and what program he is running? What his actual numbers are would help as well since beginners train differently than elite lifters.
I just came off squatting, benching, and deadlifting 3x a week each and had no problems of "overtraining", "CNS fatigue", or loss in bench strength. It's all about how you distribute your volume and build up volume over your lifting career.
"Strength is the product of struggle, you must do what others don't to achieve what others won't."
Squat: 463 Bench: 275 Deadlift: 529 Total: 1262
"Technique is always the first place to begin when striving to improve at a specific skill."
