Ramp Up Your Workout

Last night's workout at Velocity was a little too easy, which is really rare. The reason: There were five of us in the class, which meant we often had to wait for the slowest to catch up before starting the next drill.

But I forgot an easy way to have quickly made the session tougher -- a weighted vest. I've worn one from time to time at Velocity and the extra 25 pounds makes a huge difference. Even a jog is harder.

So if you want to ramp up your workout quickly, give them a try. Today's New York Times has a review of several models.
