Weight / Fat loss

Just signed up for a gym, did my first session with an instructor (I've never been in a gym before so am a complete and utter n00b). Instructor gives me 4 mat-based exercises, tells me to do 2 sets of 10 reps each, then tells me to beat it. Whole thing lasted about 20 mins. Is that really it? Was kind of expecting something a bit more intensive and / or involving the Shit What's In The Gym. Have I got a duff gym or is this what they're supposed to be like for a first session?

I'm guessing this is probably their induction for someone who has never been in a gym before. It can be that they want you to get used to working out before moving it on to weights, and build up a commitment and routine and get your body used to exercising in a certain way.

If you're not happy with the induction, tell the gym. If you want to know how to use the weight machines ask the gym. Let them know you are not happy.
