New and needing help

Hi everyone
I have been training and dieting for months but my weight has only gone up week by week. I was following ww and have now joined mfp to try something new.
In terms of training I will do:
Monday:body pump
Tuesday 2xspin classes
Wed rest
Thursday: body pump and combat
Friday: rest
Saturday: either circuits or cycle 30miles ish

Any hints or tips on my calorie intake and what I should do with exercise calories would be mucho appreciated,
Please explain in simple terms as I am new to all this and do not understand lots of the abbreviations.
Thanks in advance
