File under Ouch.

A while ago I bought a jump rope. A cheap form of excersise that requires no skills other than the ability to jump. Jump ropes are about $5. I loved jumping rope as a child. I can do this.

I did not however, have breasts as a child.

Jump rope: $5
Time it takes to get in shape: about 10 minutes per day to start.
Investing in a good sports bra: priceless.

The moral of the story is look for proper support before you jump into getting into shape.
