my trainner keeps on yelling at me because i flare out my elbows when i throw a left jab or right straight. I don't understand how to correct these problems. We probably sat there for about fourty five minutes in a private lesson going over this and i left not feeling any better about it. He's telling me to keep my elbows tight to my body and punch like i was going to do a close grip bench press, then turn it over at the end like screwing a screw driver. Are there any picks on the web that someone could link me to so i can get this right, and move on. Its extremely frustrating when i can not figure something out. Thanks in advance!
