Good news: if you're trying to get bikini-body ready, you still have plenty of time. Even better news? Warm weather can make it easier to work out outside. And instead of feeling like a chore, you can be having a blast while you burn calories. Here are seven outdoor workouts you should definitely try this summer.

1. Stand-Up Paddleboard

You can tone your whole body with stand-up paddleboard. Stand on your board and paddle to calm waters. It's less intimidating than surfing because the water is flat. But don't let it fool you. It's difficult because you use your entire body. Still, you're guaranteed to have a good time. Former professional surfer Jodi Nelson describes it as "hiking on water." All you need is a stand-up paddleboard, a paddle and a personal flotation device.

2. Golf

You may be moving slowly, but you can burn up to 1,400 calories after golfing, said GolfLink.com. Maximize your workout by walking between the holes, which can be anywhere between three to five miles, and carrying your golf bag.

3. Beach Volleyball

If you're already headed to the beach, then this might be perfect for you. Even if you are uncoordinated, you will constantly be moving. Plus adding in the sand makes the workout that much more intense. According to Randy Cline, owner of Ohio's Elite Volleyball Training Center, "You get much more resistance with each step, so your legs and core work harder with every move."

4. Scuba Diving

A shore dive can burn up to 600 calories per hour, and warm-water boat dives burn about 300 calories per hour. According to Theresa Kaplan, director of communication for the Professional Association of Diving Instructors, there are added benefits. "The amazing thing is divers can experience the strengthening benefits of diving without feeling the strain of a typical workout, as they are not sweating profusely as they would with a more traditional fitness regime and are taught to achieve neutral buoyancy, or weightlessness, while underwater," she said. A low-impact sport, diving also offers an exciting alternative to running, biking or other activities that could exasperate knee issues."

5. Tennis

If you've got a competitive streak, try out tennis. This workout helps your arms, shoulders and back. A 150-pound person can burn around 544 calories per hour, notes Prevention. Tennis also earns points for being a game you can play with people of all ages and skill levels. It can help increase your aerobic capacities, lower blood pressure and it can help with stress.

6. Frisbee

Take it back to your childhood and toss a frisbee. The more competitive you get, the more calories you will burn. And this is one sport where you shouldn't worry about showing off. You can do it just about anywhere, and it is so versatile that you can even play it with your pet.

7. Gardening

Gardening is hard work, and the result is some serious calories burned. You won't be tempted to watch the clock as you partake and you'll be doing a lot of physical activity. Digging holes, planting and weeding are some of the biggest calorie burners.
