In Los Angeles and New York, the place to pump up publicly is the ultra-popular Crunch gym. There, stars like LAURA DERN, BRAD PITT, JEFF GOLDBLUM, JULIE DELPY, JON FAVREAU, MICHAEL BERGIN, MICHAEL T. WEISS, KEANU REEVES, ALEC BALDWIN, JULIA ROBERTS, and BEN STILLER can groove on the cardio machines, hypoxic chamber and gospel and Afro-Brazilian aerobics (a fave of MARISA TOMEI and JULIANNA MARGULIES.) But while Crunch may be known as the place to meet hard bodies and pump iron next to celebrity muscle, the hip international mega-gym is now upping its interactive identity with new “Cyber Sweat” stations, which allow exercisers to go online while burning calories.

In San Francisco, Los Angeles, Miami, and New York, anyone who jumps on one of the gym’s stair climbers or recumbent bikes can access the new touch-screen “Netpulse” program and browse the web, read online periodicals, follow sports scores, receive stock quotes and place trades, watch television, access free web-based electronic mail, listen to CDs, shop, or check out the latest on Entertainment Tonight Online while they sweat into shape.

For the truly competitive, Netpulse and Crunch are currently developing several exclusive programs, including the Crunch-Netpulse Challenge where members from across the country will be able to compete against each other during an 8-week fitness competition. Throw your hat in the ring and who knows, you might ultimately go up against the likes of Hollywood’s hottest hard bodies for Crunch’s Cyber-training title.
