Hi! I currently attend a gym that is only open between 9am to 12 / 1pm and 4pm to 8pm on Monday to Thursdays.
On Fridays it shuts early at 7pm.
It's open on Saturdays between 9am and 12pm.
It's closed on Sundays.

I am looking for a reasonably priced gym in the North Kent area with decent opening hours.
It MUST have free parking.
I could pay monthly or 3 monthly but not a year subscription as I don't want to make the same mistake again of being tied down.
