New to gym- Found my routine now how to impliment

[MumboJumbo]

Hey guys, well im going to uni in 6 days and ive already paid for my gym membership. Im looking to turn my weedy body into something more athletic.

Im thinking im going to go with the strong lifts 5x5 routine as it seems faily newbie friendly and well thought out. Obviously however i know next to nothing in the area so you guys might know if its a good idea or not.

Now im wondering how do i put all this into motion. I don't want to injure my self so im looking for advice. If i went into the gym and printed off the routine page and paid for a personal instructor and said look this is what i want to do can you show me how to do it. Would this be a sensible way of going about it? Will they show me how to safety and sensibly put it all in to practice.

Also i have another problem. I dont like fish/nuts/milk, these appear to be a large part of all diets. How would you suggest i go about this?

Thanks.

:EDIT:

Also im looking for general fitness for squash/badminton/tennis etc. Would adding treadmill work into the program be advisable as im presuming weight training doesn't add much to stamina around a court?

if you are really new then look at riptoes starting strength instead imo.

why pay for a personal trainer to tell you how to do an exercise? that is what the gym staff are there for
PT's are there to motivate you and do more than what a gym trainer can tbh.

I didn't know i could just go up to the gym people and ask them to show me how to do the exercises. As for riptoes is there any reason why you suggest that over the other. They both look very similar, ive read into stronglifts 5x5 a lot and he seemed pretty confident it was best not to do dips in favour of pushups due to back pains etc. I do have a bad posture im also looking to improve.

:EDIT:

The difference to me seems to be less sets of 5 reps?

3 sets of deadlifts has me panting harder than most treadmill workouts I've done, but if it's proper cardio you want, then for squash and badminton I'd look at HIIT on the crosstrainer and rower as well as the treadmill.

Weights alone will improve your cardiovascular fitness a lot though in my experience.

Deadlifts do look pretty hefty. I was thinking that some running would improve my stamina around a court but looking at the routine i dont really know where id manage to fit it in. Possibly a sprint after each gym session if my legs can hold me up long enough haha.
