I figure I will only do with my right arm what my left arm is capable of because I don't want to be lopsided.
That's one of the reasons I begin on my left side so I know a realistic weight for it before I try it with my right.
I hear you, Jane, on not wanting to re-injure yourself. My shoulder is a lot better but I'm still being cautious. I don't want to end up not being able to lift. If something really tweaks my shoulder, I find an alternate exercise that accomplishes the same thing or almost the same thing.
Oooh, Anne, I forgot all about the back extensions. I like those because they are really easy for me!
I can do 35 pounds and bend all the way down and back up. I'm not sure I can carry a bulky 45 pound plate and do it, though. I may have to come up with an alternative...
I'll be doing 5-B-1 next Mon. I only did one set of BWN yesterday because I couldn't get Nat's video up. I did it on my own once and then I decided I didn't have it in me to do it again even after a long break. I'm doing the second set today.
