I would be extremely cautious about The Fitness First Operation - A friend of mine (won't mention his name) has been through the experience and raised the following points.

1.) No way can you live on the salary in Dubai and he has had to dip into to savings on the promise of future commission.

2.) FF do not intially sponsor your residency Visa - hence the three month intial probation so you are in effect working illegally !

3.) If you come from the UK they do not explain to you what you need to do to become a tax exile and therefore - you would be liable to pay tax on any sums you earn in Dubai once you finally return to the UK.

4.) If that isn't enough - please do some research in the web - there are many expats leaving Dubai at the moment with loads more probably in waiting for the school term to end. You have to ask yourself how many clients for personal training there will be.

Really sorry to be negative - I would encourage anybody to experience working overseas and Dubai in particular but I really do feel this would be a massive risk on your part.
