Hubertis — If I hold my bow with my feet and use my right arm to pull back on a bowstring, so that I can feel what the muscles are doing using my free left hand, the triceps and biceps feel equally tensed. Though I’m no physiologist and can’t explain why, and Doc Don Thomas is off somewhere sporting so can’t help us here, at least for a while. Maybe someone else can. But it seems that “that’s the way it is,” and you’re smart to start exercising your archery muscles regularly. For example, years ago I went on a shooting binge, a hundred or more arrows a day, and did so much damage to my right shoulder that I had to drop 10 pounds from my draw weight that I might still have had my shooting and shooting-muscle exercise not been so sporatic and voilent. An interesting question you’ve posed here. dp
