Of course you can. However, it depends on the individual's wishes. Everyone knows running, sweating and persistence, but not many people really do it. Actually, it would be better to consult a professional fitness instructor in the gym. And losing weight in the gym will have an inexplicable fighting spirit. Seeing that people around you are working hard and seeing other people's good bodies, you can at least have a goal to strive for. I think what you need is this kind of atmosphere, so at least your will won't be too thin and you won't be able to endure it all at once. Losing weight is a painful thing.
