BIL is quite serious about getting fit. And once he sets his mind on it, he will do it for sure. He is not overweight but would like to work on his muscles. How serious is he? I would say very because he is checking out home gyms from the internet and comparing prices. Although he can afford it, a little discount, of course, would be good.
I just hope that his enthusiasm will also encourage my husband to workout. He needs it more than my BIL.
