Back trouble

[spareparts]

oddly enough, Ive been doing some exercises to help with shooting that have really helped my back. Stand in a shooters stance, legs slightly bent, leaning forward, weight on your toes. Arms slightly bent, out in front holding a weight(i'm using 20 lbs). Hold it out front and count to 10, rotate to the left, count to 10, back to center, count to 10, right, 10, back to center, 10. it really helps with my core muscles, and has helped a lot wit my back, I haven't been to the range in a while, so I dont know if it helped with that or not
