Why does back training makes you look wider even from the front??

[Uglybrazilian]

I really dont get it tbh
This morning I went to the gym for my back + biceps day and after the workout I was looking so much wider because of the pump, even my sister commented saying "you are getting bigger"

The thing is how does back training creates this illusion?? It doesnt make any sense since Im training muscles which are not visible from the front
