My arms are pretty short and I'm of average strength. Here's what I do with long guns and stiff bands. Assuming you are right handed, grab the left band with your left hand, grab the gun handle with your right. Now extend the gun outward and inclined slightly upward keeping your left arm fully extended. Use your right hand to PUSH and TUCK the butt up to your solar plexus and then lower the angle of the gun so it is perpendicular to your torso. It's important that you lower the angle of the gun because this will lock the butt into your chest and keep it from slipping off while you let go of the handle. The bands will be in tension but in perfect reach for your right hand to grab a hold of the other band. PULL!!! straight back and stick your chest out to get an extra few inches.
