How Ironic bro my wife is 5'2 and she weighs 124 with a phenomenal ass. My wife trains with me 5 to 6 times a week she does chest, back, legs, shoulders, biceps and triceps. Also abs every other day cardio every day. With that being said she used to think the same way your wife does. I dont want to get bulky. After the 2nd month she started getting really nice definition body and she also gained a few pounds but dropped the body fat. She trains each muscle group with me very hard, and she hasn't bulked up just got in very good shape. Tell your wife she won't bulk up she'll just tone out. Hope this helps.
