What are the best strength exercises for someone (54 year old male) with low back pain and knee pain? This person is pre-hypertensive and has a BMIi of 39. Wants to lose quite a bit of weight and has never lifted weights before. Any suggestions on some exercises to be prescribed? (legs, core, back….). I don’t want to overwhelm him with too much.. since he has never lifted. How many reps and sets are appropriate for this client?… (8-12, obviously low weight… perhaps 2 sets? Thanks so much!
