I would agree with the others. I also started recently (2 years) and started out with an old 44# recurve. Initially I too couldn' t shoot more than a few dozen shots and couldn' t hold my draw for more than a few seconds without really tiring out.

The other thing about trad shooting is that it can become very frustrating. Minor changes in your form can really play havoc on your accuracy. It will become very tempting at times to hang it up and go back to your compound as I have almost done many times. It' s all about patience, practice, perseverence and asking for advice (lots of advice) all the great people on this board.
