Exercise number 1 - Sour Grapes:For this stomach toning exercise focus on your lower-body movements by standing with your legs wide apart. Start by lifting one knee at a time in front of you, stomping or pumping your legs alternately left and right, as if you were stomping grapes. Make sure your feet touch the pool bottom each time. This movement helps your buttocks and thighs while assisting to give you firm abs as they work as stabilizer muscles. This is one of my favorite exercises for developing perfect abs because it's also fun to do!

Now you want to focus on your upper-body movements by spreading your arms out wide in front of you. Bend them just a bit as not to put excess stress on the elbow joints. Now push one arm down as hard as you can to your hips, then returning to its starting point. Switch arms and repeat the exercise. This movement works your upper back, the back and front of your arms and your shoulders. Again, you will be toning your abdominal muscles as they work to stabilize your other muscle groups. For greater intensity, wear water gloves. This is a great total fitness exercise that will increase your metabolic rate and speed up the process of developing those perfect abs.

Exercise number 2 - Ski Master:For this exercise focus your upper-body movements by reaching and extend your arms out to the sides at the water's surface. Press your shoulders back and down, with your elbows slightly bent (don't lock them as this will put unnecessary stress on the joints). Then lower your arms down to your sides, and raise them back up to the surface. This movement works your shoulders and back. Again, keeping proper posture will give your abs a good secondary workout helping to keep a firm tummy!

For the next part of this stomach toning exercise you'll be focusing on your lower-body movements by stepping into the lunge position; placing one leg behind the other - don't lock your knees. Flex your knees, hop and switch legs, as if you were skiing. This movement aids you rear and your legs. This exercise is particularly effective at working your lower torso while giving a killer abs workout at the same time. Simply a great way to gain that flat belly you're working towards. You may increase resistance with any of the exercises above by using water paddles, water gloves or aquatic hand buoys. Remember to rest your upper body as needed during exercises.

By doing each of the above stomach toning exercises for 3 minutes, then jogging for 30 seconds between exercises, you should burn about 100 calories in just 10 minutes. Of course the more reps you do the more calories you will burn. Try doing these water workouts two or three times a week as an alternative to your normal abs routine.
