I'm an underweight person. I can't join gym neither I can buy expensive equipment. These Dumbbells seem worth my budget.
But I read at some sites that dumbbells are for making arms strong. So ultimately that will increase weight of arms only?
And if I am wrong, can I use them to increase my overall weight and gain a normal weight (I don't want to be muscular, just need normal weight)?
Secondly, for a person with 174 cm height and around 55-58 Kg weight, how much weight of dumbbells is recommended?
