Flutter kicks are an intense abdominal exercise. It may not seem like much of a challenge at first, but the challenge will become readily apparent as the seconds turn into minutes.
Lie flat on your back, with your arms resting palm-down by your sides.
Step2
Lift your heels about six inches off of the floor. Keep your legs fully extended, with a slight bend in your knees.
Step3
Now, quickly move your legs up and down, alternating in small, rapid and scissor-like motions - as one leg goes up, the other comes down. Use your arms to stabilize you, but keep your lower back flat against the ground as best as you can.
Step4
Continue these motions for as long as required, as per your level of fitness. Keep your abdominal muscles contracted throughout the exercise - they should be doing most of the work.
Step5
When you have had enough, or have reached exhaustion, slowly lower your legs to the floor. Afterwards, give your muscles time to rest and recuperate.
Tips & Warnings
You can alter the intensity of the exercise by changing the size of the kicks, or the height you hold them off the ground.
