@karendb- Start with the arm exercises, which are a the bottom of this list. Star with no more that 5-8 reps. If you don't understand the positions then google them and watch while someone does it, even if it's with weights. https://www.cancervic.org.au/living-with-cancer/exercise/strength-training-exercises.
I'll also answer any questions that you have about them. Take it slow. Do not get out of breath. Rest in between each exercise or 1/2 minute. Don't strain yourself!
