Thanks for the welcoming

Nice to learn this great sport.
İn my country, archery is, or atleast used to be very a sacred and important activity. Turks and the Huns that are related to them were very well known for their great horse archers. I've always been fascinated by archery since I learned about the role it plays in my countrys history.
Alas, here archery doesnt have the importance it used to anymore. I found one club, and now their training us for the national team.
Right now I'm using a recurve they gave me that has pretty much no "gizmos" attached to it. I didn't shoot an arrow with it yet though, their making practice drawing it fully without a finger ring, holding it for a few seconds, then gently letting go without releasing. It really hurt my fingers
Do you have advice for this budding archer? Should I get my own bow, and does it matter how big I am? I'm 180 cm (5.9 feet) and broad shouldered, does this affect what kind of bow I should use?
Sorry for all the questions
