hi guys! as someone who works offshore for 2 months at a time i find i come back nice and fit but of course not the muscles we use for bow shooting. as it is not possible to take my bow with (for one i might be tempted to try some live target practice on certain morons) is there any other form of excersise one can do to keep drawstrenth up? its bad enough only being able to shoot one month out of three but then i have to spend two weeks getting in shape as well! any suggestions?
