Nobody wants to expose their spare tire to the sunlight come summertime – that’s why millions of people flock to the gym as soon as the winter ice thaws. But if you’ve waited until the last moment to get swimsuit-ready, you don’t have to take out an expensive gym membership and fight over a spot at the elliptical in order to get in shape. There’s an abundance of fun activities that will burn calories before the sun burns your flab. Below are common workouts that don’t involve weights or machines for people who want to get or stay in shape during the summer. The tally of calories burned accounts for 60 minutes of activity and it’s calculated by Health Status. It’s also based on the average weight of American men (rounded to 195 pounds) and women (rounded to 165 pounds) ages 20 and above according to the Centers for Disease Control and Prevention.

• Swimming
  What man wouldn’t want to look like Michael Phelps? What woman wouldn’t want to look like Summer Sanders – at her current age and during her days as an Olympic Gold Medalist? Chances are you won’t, but with a consistent swimming regimen, you’ll be a step closer to possessing a hot bod by working out your arms, chest, shoulders, back and legs. It’s a perfect way to exercise while staying cool as the temperature heats up. A man and woman who swim at a moderate pace burn 538 and 455 calories respectively.
• Kayaking
  If you’re fortunate enough to live by a clean and safe body of water, consider taking up kayaking. If you don’t own a kayak, you can purchase one at a relatively inexpensive price at your local sporting goods store – some can be found at well-below $300. There are also kayak rental places nearby many frequently visited lakes, rivers and streams. A toned upper body is the result of consistent paddling. Men burn 444 calories while women burn 376 calories on the water.
• Volleyball
  Whether it’s beachside, poolside or on an indoor court, a game of volleyball is a fun all-inclusive activity for people of all ages. Players typically have strong upper bodies and well-toned legs – just look at Tom Cruise in Top Gun or Olympic legend Karch Karai. During a recreational match, men burn 304 calories and women burn 257 calories.
• Baseball/Softball
  Participating in America’s pastime, or a variation of it, is an excellent way to blow off some steam, be social with your friends or coworkers, and lose a couple of pounds. Firmer arms, shoulders, abs and legs result from swinging a bat, tossing a curveball and running the bases. And contrary to popular belief, you don’t need steroids or human growth hormones to play like an All-Star. Men and women lose 444 and 376 calories respectively on the diamond.
• Basketball
  By getting a Basketball Jones, you’ll not only engage in an excellent cardiovascular exercise more consistently, but you’ll have the opportunity to make more friends. You’ll interact with other hoops enthusiasts through informal pickup games and adult leagues. Regardless of whether your skill level is comparable to an NBA player or a four-year-old, the outcome will be a more toned midsection and stronger legs. During just a half-court game, men burn 725 calories and women burn 613 calories.
• Tennis
  You and a friend can motivate one another to get in shape by competing in friendly games of tennis. You just need a couple of rackets, a container of tennis balls and an available court. Tennis players are known for having toned arms and shoulders, strong back muscles and sturdy legs. Men and women burn 538 and 455 calories respectively while participating in singles matches.
• Golf
  Many consider golf somewhat of a lazy sport – you don’t have to change out of your work clothes to participate. But walking through eighteen holes and taking dozens of swings can be tiring. Consistent golfers workout their arms, shoulders and backs. Men and women who bypass the carts and carry their clubs lose 538 and 455 calories respectively – the same as tennis. Don’t underestimate the heaviness of your clubs.
• Rock Climbing
  If you happen to live by mountains or large hills, you can explore them through rock climbing. Or if you live where it’s completely flat, you might be able to find an indoor rock climbing hub. It’s perhaps the most physically demanding sport; climbers strengthen their legs, arms and cores while building overall physical endurance. While on the rocks, men burn 971 calories and women burn 821 calories.
• Hiking
  Even if you live in the biggest of cities, there’s bound to be a scenic trail or two within several miles of the city limits. If possible, take the drive out and become one with Mother Nature. Walking for an hour – especially where the land isn’t flat – a few times per week will build leg muscle and flatten your stomach. If you can’t leave town, walk around the city. Either way, you’ll be taking steps to improve your appearance and health. Male and female hikers burn 526 and 445 calories respectively.
• Biking
  Hiking and biking can go hand-in-hand if you find the right trails or paths. But there’s nothing quite like a miles-long trip to a remote location that you wouldn’t be able to access by foot in a timely manner. Some people invest thousands of dollars on their bikes. Their passion of riding also serves to keep their legs, hips and backs strong while ensuring they don’t acquire a spare tire. It’s also great for the heart. While just leisure biking, men lose 351 calories and women lose 297 calories. Mountain biking can result in losing more than twice those amounts.
• Skating
  You may not notice nearly as many people skating as there were during the ’80s and ’90s, but there’s no denying its physical benefits. Inline and roller skating are efficient aerobic workouts that build muscle in your lower body. Men and women lose 444 and 376 calories respectively when they skate moderately, and those amounts almost double when they skate vigorously.
• Frisbee
  A relaxing game of Frisbee in the park with your friends is a light way to work out your entire body. If you want to take it up a notch, ultimate Frisbee requires constant movement; not unlike soccer. In fact, serious team competitors spend hours training and resting in between matches – it’s that serious. During a regular game of Frisbee, men burn 269 calories while women burn 227 calories. In ultimate Frisbee, men and women burn 748 and 633 calories respectively.
