The Pulse

RERUNNER

Part training aid, part Pavlovian torture device, the wireless ENTERTRAINER connects a heart-rate monitor to your television. Fall below your target range during your treadmill session and you lose the sound, and, eventually, the power. $129; www.theentertrainer.com

MOO JUICED
Fitness pros may soon be filling their water bottles with a creamier sports drink. A study by researchers at Indiana University found that CHOCOLATE MILK consumed between successive workouts on the same day rehydrates as well as any fluid-replacement drink and outperforms carb-rich formulas. But don't go laughing the Gatorade out of your nose just yet. The study tested only nine male cyclists—none of whom were lactose intolerant.

SCAN AND DELIVER
The new CALORIE SCANNER from Training Peaks works like a pocket-size grocer's gun, but instead of reading prices, it stores nutrition information from any of half a million product codes. Then, using your computer, it charts the calorie, fat, carb, and protein content and graphs your intake. For obscure items, the scanner stores the number and allows you to upload the product details to a Wiki-like database, so next time you—or anyone else—scans the item, it comes right up. $149, plus $20 monthly subscription; www.trainingpeaks.com—Kyle Du Ford
