It might be a good idea to try something different when working to improve your shooting accuracy.
I haven't worn one since I was a little kid and my parents had me taking archery lessons at a local range with a 25 lb recurveNice article. One of the biggest problems and the reason some where an arm guard is gripping the bow. Some people wear an arm guard to contain the shirt sleeve but a lot wear it because they hit thier inner forearm with that sting.
I find the biggest reason why people do this is they are gripping the bow hard which naturally tends to draw your hand inward tilting the string towards your forearm. One should be able to basically open your hand at full draw and the bow not move just sit cradled in thumb joint. Tight bow grip is also one of the the biggest cause of right and left misses I find.
My best friend had a terrible problem with this until he developed an unusual way of holding the bow with his wrist tilted flat and holding the bow in his fingertips not even around the handle. Very odd but it worked for him, he was an excellat shot til the day he died. We used to play horse all around the shootibg area, was fun. Even shot laying on stomachs arched upwards. I generally release tension but keep in place all my fingers except thumb and forefinger to keep the bow from falling, there is not even conscious thought in doing this, it's muscle memory.
I have not worn an armguard in 50 years.
You, are an archer, difference between these people who just shoot a bow, of some type usually with a million gadgets, and an archer. One of the best ways for me to relax is shoot the bow.I haven't worn one since I was a little kid and my parents had me taking archery lessons at a local range with a 25 lb recurve
