Get her a couple of 15 pound dumb bells, and have her do shoulder presses,3 days a week on the off days that she is shooting. Also , bent over rows with the same weight, and 'girl' push ups. Each exercise should be 3 sets at 6-8 reps, but if she can only get a few reps on the third set, no problem. Keep using that weight until she can easily do the 3 sets, and all reps--then it will be time to move up to 20. In a month , you will see her pulling the legal weight with ease--and she might be able to kick your butt!
