When working out with a dumbbell, increase good form because you cannot use your body weight for momentum when lifting. 

The main downside of a dumbbell is that it can be hard to increase weights, so you might need to get another piece of equipment if you want to change a kg. You can start by reaching out to a manufacturer like Liftdex Strength & Equipment for quality exercise equipment. One reason for this workout equipment is that it increases your strength of working out every morning if you have it at home. The manufacturer allows installment payment and free delivery to your doorsteps.
