This isn't just about the gym anymore. There is a big difference between being strong in the weight room and being strong wielding a weapon. I don't know the weapon laws for many places, but where I am, I can have weapons on my own property. The weapons I mainly use are a staff and sword. I also have some skill with small blades.
I was using my sword today and it was actually heavy. I also noticed the shoulder work that comes with the staff. I think I'll have to start practicing with these again because weights are no help in this area. I'll also need to find a sparring partner soon.
