You better hope that she meant that for you

You better start working out your knees.

Brace yourself. She has grown discontented due to the chatter of her girlfriends and is about to "trade up". This is why she hired the trainer in order to move up the ladder at least in her mind, though the trainer may not be whose knees she wishes to make weak…but it is doubtful she is referring to you.

you guys are freaking out over nothing. she just wants to look good for you and therefore make you weak in the knees…

it means your a lucky bastard. pay her back properly by getting fit right there with her. the more she works out the better she looks, the better she looks the more YOUR knees go weak.

1. Compliment her on her progress.
2. Buy her something cheap and silly that only she would appreciate.
3. Do a couple more sit ups.
4. Become her "trade up"

If any of you think that it's too much work for a girl, ask yourself this, "couldn't I stand to look a little better?"

She's going to dump you, there isn't an ounce of doubt about it. You should probably dump her as a preemptive measure.

You're an idiot. It's YOUR knees that are supposed to get week. You are not very sure of yourself, are you?

Dude are you working as hard to keep her as you did to get her? If not then you should probably worry or follow Kevin's advice…which is hilarious. Also your insecurity is not sexy.

Does no one else think that this is referring to women wanting men to propose? Bitches always wanting to get married

She's trying to get in shape to make you more attracted to her. Dumb ass.
