Ive been going to the Gym without my parents knowledge

I’m 17. I’ve wanted to start going to the gym since I was 14-15 years old and have been wanting to improve myself. Fast forward a year later we immigrated to Canada and met alot of kids my age who did go to the gym. I was pretty motivated to go and my parents kept saying no until I got pretty tired of asking them and went behind their backs to get a gym membership. Ive been going to the gym since I was 16 and it has been a year without them figuring out why I suddenly go out for 2-3 hours a day.

The very reason they don’t want me to go to the gym is that I wont grow any taller, I know this could be true for some people but as a Filipino we have a reputation for being undersize or short. Ive been at 5’5-5’6 ever since I came to Canada and haven’t grown a sincle centimetre since I immigrated here and that’s why I also decided to just go for it.

Ive been feeling guilt ever since I started doing this but i dont have any regret but i fear that they will not trust me again after finding out, I dont have any intentions of telling them soon. I just wanted to get this out of my chest
