Jason lets practice on is 20yr old youth bow. Let me tell you technology has come a loooong way. I had go work up to the 40# too, Jason would set the weight back on the bow weekly. I started off at 15 and worked up to 40. But like my dad said, never dry fire. Jason would let me pull back on the bow and slowly put it back into the normal position, that way I could get used to string placement near my face.
