Hi Toly. I don't think of this statement as being bold or controversial. Go to just about any instruction site and you'll see something similar said. It's completely consistent with what I see when I watch pros and high level players hit, and it's completely consistent with my own personal experience.
Meaning no disrespect, but it just seems really obvious to me. Yes, I am a mechanical engineer. As an engineer I'd tell you that muscles groups in your legs and core are far stronger than the muscles in your shoulder alone. Wouldn't it make sense to utilize those stronger muscle groups in generating power? An analytical analysis would need to take into account.
Seriously, just go out and hit some balls. Can you hit it harder when you use just your arm, or when you use your legs and body too? Do what works for you and have fun.
