Is it possible to get in shape at home?

Is it possible to get in shape at home? (as an aid - training video)

+ proper nutrition

as a video, you can use the gurus from Hollywood

I am 17, weight ~ 70, height 182, at home there are dumbbells with pancakes and a special bench. Once I tried to pump my body, a year passed and I threw it, muscles appeared (biceps, shoulders, a little chest). Now I decided to get in shape, at least. I have a layer of fat on my stomach, the press is visible, if with effort with your hands to hide the fat, there are small sides and a little breast with fat. My goal is to remove excess fat and sides everywhere so that they are not there after months of training and at least a little relief, to make it clearer, like boxers or football players, they do not have excess fat, the press is a little torso, and not pitching.

It needs a strong personal motivation. Indeed, in a group it is much easier than alone at home
