Recreational pursuits such as biking, hiking, and inline skating allow you to reap up to six times more fat-blasting, body-shaping benefits than cruising around the neighborhood on foot. And you don't have to be a hard-core athlete or fitness freak to get the most out of the five we're suggesting. Top off your normal weekday exercise routine with one of these exhilarating weekend activities, and you'll be firmer and fitter by mid-July.
Weekend 1: KayakingCalories Burned: 340 per hour
A sculpted upper body. "Pulling the paddle against the water is great resistance," says 29-year-old Michelle Christensen of Baltimore, who spends summer weekends kayaking around the Chesapeake Bay. "You target your shoulders, triceps, biceps, back, and core."Weekend Benefits
It's like meditating on water, says Rhett Pruitt, a 34-year-old raft guide and recreational kayaker in Long Creek, SC. She opts for tranquil sea kayaking over exhilarating white water when she's craving peace and quiet. "Sea kayaking is not intimidating," she says. "You're just inches above the water—the perfect vantage point for taking in the abundant wildlife and sea life that you would never see otherwise."
Word to the Wise
Beginners should use an open kayak—or take a lesson to learn how to escape the kayak first.

Weekend 2: HikingCalories Burned: Up to 400 per hour
Improved cardiovascular fitness. "There's a lot of lung cancer in my family," says 49-year-old hiker Lynn Anderson, from Helena, MT. "It's always been a priority to keep my lungs in tip-top shape." Plus, hiking will give you stronger, leaner thighs and firm your rear to boot.
You get to unplug from society. Hiker Lori Pfankuch, 47, who traverses Glacier National Park in northwestern Montana, says: "Hiking takes you out of your world so you can reflect. I've seen mountain goats, I eat huckleberries on the trail, and last summer I saw my first grizzly bear."Word to the Wise
Invest in a good pair of boots or trail runners (go to Backpacker.com for a buying guide) and be sure to break them in by wearing them on errands before you hike.
Head to Gallatin National Forest in Montana or the Grand Canyon's South Rim in Arizona. For hiking clubs near you, check out the American Hiking Society.
Weekend 3: SpeedmintonCalories Burned: About 400 per hour
Tank-worthy arms. This hot new game is a cross between racquetball, badminton, and tennis but with no nets or walls involved. Players bat a speeder—which looks like the birdie used in badminton—back and forth using lightweight racquets.
"If you can swing a racquet, you can learn to play, and it's great cardio," says 30-year-old Christina Higgins of San Diego, mother to a newborn and a toddler. "The results are similar to those in tennis—sculpted arms and back, toned legs, and better hand-eye coordination."
Time with friends. "Our neighbors introduced my husband and me to the game, so now we all play in our cul-de-sac," Higgins says. "The speeder glows, so we can even play well into the night."
