After a predawn start, a bout with jet lag, and a triple-meeting afternoon, you're ready to head to the hotel bar rather than face an aging rowing machine stashed in a dank, windowless room. Put that martini on hold. You'll feel better during and after your trip if you squeeze in a workout, and we're here to restore your motivation with a guide to fitness-centric hotel services, the perfect in-room regimen, smart tips from a travel-savvy exercise physiologist, and more. Take our advice and you can retire to the bar and toast your health.
Hotels nationwide are catering to health-conscious travelers. Here are eight ways you can reap the rewards.
 PERSONAL GYM: Stop waiting in line for the cardio equipment and book a WestinWorkout room. For about $20 more than the standard-room rate, you'll get a treadmill or spin bike, adjustable dumbbells, and a stability ball, plus a fitness library, training videos, and total control over the remote. www.starwoodhotels.com/westin
 AWAY GAMES: What's better than a hotel with a gym? A gym with a hotel. At Renaissance ClubSport, in Walnut Creek, California, your room comes with 12,000 square feet of workout space, an Olympic-length swimming pool, and full-size basketball and racquetball courts with regular pickup games. In May Renaissance broke ground on a second ClubSport, this one in Southern California. www.marriott.com/property/propertypage/oakbr
 ROOM WITH A RIDE: Call down to the Fairmont Chicago's front desk and an hour later you've got a Trek 1000 road bike. Take it for a spin on 21 miles of paved paths along Lake Michigan. $15 per hour; half-day, $50; www.fairmont.com/chicago
 CARDIO TO GO: Omni hotels deliver stationary cardio equipment to your room. Reserve a treadmill for $15 and it'll be in your suite upon check-in, so you can go for a run without going out. www.omnihotels.com
 ADRENALINE CONCIERGE: The Rock Stars program at selected Rock Resorts one-ups the "dude at the front desk" found at typical mountain-town hotels. Exhibit A: The Lodge at Vail's "spokes-person" is charged with dishing beta on the area's singletrack. A climbing guide is in the works for the chain's Keystone Lodge. www.rockresorts.com
 FITNESS CHANNEL: Order one of ten complimentary on-demand workout programs covering the likes of yoga, Pilates, core work, and meditation on the new Mind.Body.Spa channel at Kimpton boutique hotels (yoga mat included). Westin's DVD-based fitness programming includes similar offerings, as well as spinning instruction. www.kimptonhotels.com
 GYM BAG: Omni, Kimpton, Marriott, and Hilton all offer bundled exercise equipment you can take to your room at no charge. Hilton's Fit Kits include sets of low-weight dumbbells, yoga mat, resistance tubing, and a 30-minute workout book. Marriott provides the BodyRev, a handheld cardio-and-strength trainer. www.marriott.com, www.hilton.com
 NEW YORK EXCLUSIVE: Manhattan's Affinia Dumont features exercise equipment delivered to your door and rooms with full-length wall mirrors and ample workout space. You also get access to a wellness library, an exhaustive city fitness directory, and a minibar stocked with healthy snacks. www.affinia.com
