I just have to tell y'all this:

Remember that stupid exercise that broke my knee? (Well, sprained it and made it make weird popping noises.) My trainer emailed the woman from whom she'd learned that move, and got the following breezy response:

"My clients wear knee braces during plyometrics to prevent that sort of injury."

Auntie Jo just made up a new rule. I am pretty damn hardcore in my workouts, but I will stick to this one:

If you have to have protective equipment to prevent a lifelong injury *while working out in your own home*, YOU ARE DOING IT WRONG.

In lighter news: My new trick knee went out from under me last night at work, causing me to lurch forward suddenly. The patient whose room I was in looked up from the bed and said, "Oh! I didn't realize Toyota was making legs now!"
