Could anybody recommend me some good exercises to do to have more toned arms ?

I have two 5kg dumbbells. I’ve been doing push ups (against the wall 💀) for two months now and while I have more muscles than before, it’s not really producing the results I would like, aesthetically speaking.

I already work out 3 times a week for an hour so I am looking for quick exercices to add to that. I don’t really have the time or energy for really demanding exercices.

Video tutorials would be great (or creepy-looking WikiHow tutorials), just because I don’t really know much gym related vocabulary in English lol.

Hopefully somebody can help.
