Re: Motivation needed
Not at all, weights are in fact the best and the fastest way one can lose flabs of fat, more reps with light weights is the way to go though, heavier weights are what causes one to gain muscles cause it tends to break tissues, the body responds by repairing them and then rebuilds another batch of new ones = more muscles or the muscularity look.
Concentrate/Exercise mainly on the body parts that you think need the most help with light weights. If you could mention what body parts they are I’d be glad to list down exercises meant just for them.
Sleep is absolutely essential for your body to respond well just like water is for us humans to live, for everyone, looking to build muscle or lose fat, 7 to 8 hours sleep atleast, no excuses. Water is another, drink lots and lots of water, a gallon minimum, someone who has to lose fat needs to sweat so you need to keep yourself hydrated. I don’t know how the weather is like in your part of the world but I’d suggest you to avoid anything that prevents you from sweating (I know its gross but it helps big time) avoid direct cool air while you’re working out, technically anything that prevents you to sweat, avoid it. However it doesn’t mean if you don’t sweat you won’t lose, you will lose regardless, but sweating helps to lose fat considerably faster than normal.
Honestly If I was you I’d keep the money and just do the most basic stuff, the internet is full of resources, every question/help you need will have answers already on it, you just need to be on the right place, and the forum I mentioned earlier is in my honest opinion the most helpful, has helped me immensely in my quests so far.
I’ve also heard of certain incidents where trainers were intentionally not willing to guide their members/students right solely based on the fact that If the members reached their goals quickly they won’t need the trainers = Trainers won’t get paid. I’m not saying everyone does that but some actually do resort to such stuff, and it makes perfect sense why they do as well. What you’re after is not rocket science, all it needs is strong dedication, once you have that and you’re doing things right you’ll see the change you 're after sooner than you could imagine Insha’Allah. If me promising can help, I’d be glad to do it. 
Good Luck again.
