Seriously, like I said, just try ClubFITT first.
After trying it a few times, then and only then can you decide
whether a membership at a commercial fitness centre would work for
you. Mind you, you need to sign up for 1-2 years of membership at
one go, which would cost you a few hundred at the very least.
At least if you decide that gym training doesn't work for you
after your ClubFITT experience, you would have only wasted a few
dollars.
