I always choose gyms that are IPFA affiliated (International Physical Fitness Association). Sometimes it can cost a tiny bit more on the membership, but with any gym that is IPFA affiliated, you can work out at as long as you have the documents to show your gym participates in the program & your membership is active, the gym you are attending participates, and it is not within 30kms of your own gym. I won't join a gym that does not participate, as, if I move or travel (even to another country), I can still use my membership. When you move you can transfer your membership to another IPFA gym, and use your current membership until it runs out (as long as you have had the membership for a certain amount of time). It is a fantastic program!
