Chub rub (n)
Red, angry chafing produced when your thighs rub together during a run.
Take action: Try the New Balance running dress ($70) over the seamless boy short ($38)--it'll take the hit for your thighs. (newbalance.com)
Short, intense DIY intervals that increase cardiovascular capacity. Not gas-related.
Take action: Pick a marker--a utility pole, the refrain on "Hollaback Girl," the 30-second mark on your Timex--and crank up your pace until you reach it, then return to normal effort. Aim for five to eight repeats in at least two workouts per week.
A finisher's medal--not the coveted gold, silver, or bronze but the one every participant gets for completing an event or race.
Take action: Rake in the best hardware at the Nike Women's Half Marathon and Marathon in San Francisco on October 19. Finishers get a specially designed silver Tiffany necklace.
Long, slow distance--an hour-plus exercise session held at a conversational pace that builds cardiovascular endurance. Any high you get from this LSD is purely endorphin-generated.
Take action: If LSD at the gym seems decidedly untrippy, switch machines every 20 minutes or so.
Stanky gym clothes that have been festering in your gym bag for a week.
Take action: Win Detergent contains hydrogen peroxide and an antibacterial agent that removes odor molecules instead of just masking them with a perfume. ($14 for two 21-ounce bottles, windetergent.com)
Rest, active (n)
A power walk, a relaxed swim session or a similar easy workout in which the goal is to get blood to your muscles for a rapid recovery the day after an intense exercise session.
Take action: Set a stationary bike's resistance so you can feel the tension, but it's not too challenging. Grab your favorite celebrity rag and pedal for 20 or 30 minutes.
Show shape (v)
To shine your high beams at the gym.
Take action: Pick up the Moving Comfort Dori sports bra ($44, movingcomfort.com for stores). Light padding keeps your nips happily undefined. For more smooth solutions, see "Bust a Move."
Embarrassing noise emitted from down there. Usually occurs when you come down from an inversion posture in yoga or do situps. As for the word's origin, well, think about it.
Take action: Squeeze your pelvic floor muscles so you feel as if you're stopping the flow of pee; hold for two seconds, then release. Do three sets of 10 reps daily.
