I was talking to a weightlifter I know, he recently had surgery on his shoulder to repair a weightlifting injury, and returned to weightlifting on recovery. I pray he is not injured again, and he knows and has known about "Isometric Weightlifting Exercise" for decades; but said he is not interested in that. His two young adult sons lift weights in a weightlifting room in the house and attend College. He complained about soreness from lifting. But will not be using Isometric Weightlifting! God bless that poor man. I am sure many of you have seen this before.
My Weightlifter buddy stopped weightlifting, and started Isometric Weightlifting on recovery after surgery, he uses a 5 foot red oak staff for a barbell and it helps him to hold something in his hands to focus and he loves lifting without injury!
It hit me that friend of mine is traveling a middle road, he is using machines with light weights and using dumbbells with light weights and "Isometric" resistance at the Gym! A blend of weightlifting and Isometric tension ie a form of Powerflexing! My other friend the former weightlifter uses a wooden red oak, five foot long fighting staff as a barbell and Reflexology wooden oak footrollers as dumbbells; another middle path mixing Isometric resistance and weightlifting. These guys and others doing the thing are using a blended method to help themselves.
