Fitness First Darlinghurst, or FF Darlo, is a relatively small gym compared to other Fitness First around the world or even just Sydney for that matter.
The gym has the usual FF facilities, but after work from around 4:30pm to 7pm weeknights and on Saturday around lunch is packed! Don't expect to get any machine or equipment you want straight away.
The people that go here are the usual crowd so if your a regular you can offset what machines everyone is using by doing weights on a different cycle.
As a side note, this gym is very gay orientated. Saying that everyone is very friendly and has a great vibe about it.
