As the title says, I'm thinking of doing a gym and the costs are about £30 to £60, does the car parking come with the gym membership or do you pay extra to park your car ?

depends which gym you choose?

have you considered Fitness Unlimited which is only £24 for a peak membership? parking is free at 3 of the venues you can use with the membership and with a minimal charge for parking at Ponds Forge in the city centre.

me and my friends are members at Fitness Unlimited, it's like private club facilities at public prices. You can use any of the gyms at 4 of their venues, swim at any and do classes at any. you won't find that anywhere else in Sheffield. I'd definitely reommend it.
