Let me chime in )) I can relate to the topic, I used to be through it. I am being through it, actually. :D
I played exercising videos. First I bought a subscription, but then annulled it, because everything is at free access actually)
But yes, there will be no quick results, you need to exercise for at least 20-30 minutes every day and also eat healthy, without roasted stuff and sugar and fast food, etc.
So, just read this topic )) If you do not have time to study the stuff yourself, try some weight loss center, they will measure you and calculate calories for you (I used to go to London Weight Management, if you are interested. If you go there, sign up for Jessica, I liked her better than others.))
