I've gone to resting the gun on the dreaded toe for at least 2 or 3 shooters instead of holding it at the ready and that has helped the mid and low back tendency to tire. Also turning a bit toward the trap house so I'm not spending the entire time semi-turned at the waist has also helped. You gotta try to really relax more between shots but it takes some changes in your routine.....breakemall....Bob Dodd
romie, regular setups do not do it, get one of those exercise balls, and do setups on a ball, and use your stomach muscles to roll up on the ball. Another exercise I do that helps, is sit on the ball with the bands stretching from the backside and arms down to waist level and throw a punch towards the floor and hold it for 2 or 3 count. This will tighten up the opposite side back muscle, and this has really helped me. 10tenner
Romie check your stands when you mount your gun and are ready to shoot if you know a good shooter or a shooting couch have them take a look at your stance to see if you are leaning or if you are not in a netrual stands that your weight is not center or that you are leaning trying to hold the gun up if so this can be your problem and this could be why your lower back is hurting try it my help you find the problem
It is more my middle back and I do lean in to the shot a little I think.I think I am at the point where I could use a little help.I start out a ball of fire and then after 50 my scores sink like a brick.
