Weight Lifting

Yes and yes it works if you keep at it.

I do restance with bands, Pilates, and a few machines in the gym. Must admit I am seeing an improvement.

I do pilates and our exercises always include some that require us to raise ourselves on our arms and support ourselves there while we do other exercises. It works - and you strengthen every other muscle in the same session.

Yes, what tanith said. I've been going twice a week for about 4 months and really enjoy it.

Not exactly lifting weights but I use machines at my gym that involves resistance weights. My arms, legs,bum and shoulders are much stronger and less flabby since I started. I only do it twice a week.

Yes I lift weights, physio has me lifting weights to get mobility back in my shoulder.
