Weekend off - Daughter stuff

My daughter has recently become interested in shooting trap or skeet.  We scheduled a session at the local gun club for her first lesson.  We got past the safety part and then moved on to holding a gun in the proper stance, and that's when we ran into a problem.  She didn't have the strength or body mass to hold the 20 ga. shotgun without leaning quite a ways backward, which is not the proper stance.

Proper stance is supposed to be more forward-leaning like this...

But her stance was backward-leaning like this...

Which on a small gal will probably lead to fatigue, if not being knocked over by the recoil.  Anyway her muscles were giving out just trying to get the stance right, so we stopped and tried to figure out plan B.

Plan B is building muscle.  She has been working arms, shoulders and chest for strength.  We also investigated getting a 410 ga. shotgun for her.  Pointer makes a pretty nice little shotgun, which she found much easier to hold in position.  I don't know anything about the gun quality, but it looks nice.  I am certainly not an expert on these things...
