I had a bad experience with the EFM club in North Melbourne.

I purchased an online voucher to use the club for 1 month. I was supposed to get access for one month, a fitness assessment, personalised workout plan and nutrition guide. I didn't get the personalised workout plan and nutrition guide.
Because of my personal circumstances (i.e. not able financially to join the month after using the voucher), and because I did not pay a lot for the voucher, I was treated differently from the 'regular' customers.
I was told that I was welcome to use the machines, and that I would be told if i was doing an exercise incorrectly, but that I wouldn't be able to have the same attention as their 'regular' customers. Because I lived close-by, I was not even shown where the toilets were, told that I would 'probably use my own anyway'. While other people were given written instructions on their workout cards, I was just left to do my own thing. I didn't even have a card to record any of what I was doing or was supposed to do.

So, I do not have a good impression of this business and would not recommend it to anyone. The other people there did seem happy. Perhaps if you fork out the $$$ you won't get the second-rate treatment I got.
