My ears get blocked after rowing?

Question

When I go on the rowing machine, I normally go full on for 3 minutes.

However after the 3 minutes, my ears are almost certainly blocked... they unblock like 5 minutes later...

I'm really confused!

Answer 1

no way that happened to me too the last time i rowed on the machine but that was the first time and it was when i did a 500 at a 38..

so i guess its probably normal, a lot of pressure building up maybe?
