Re: After a back fusion surgery 5 years ago, I want to join a gym.
See if you can find a gym that has truly qualified personal trainers. That, and knowing what restrictions your doctor gives you, may help you find what exercises and machines will work best for you. I've known some people who hire outside trainers (since they aren't confident in the ones the gym has) for some physical training. You may be able to do this for a short period of time - learn what works - and then go off on your own to the gym. That being said, personal trainers are not cheap.
