This exercise works the abs and develops coordination by working out the stabilizer muscles.
Lie down on the floor. Bend the knees and place your legs on the fitness ball.
Place your arms behind your head or cross them on the top of your chest.
As you inhale, arch your back stretching your abs muscles a little.
Keep your neck stationary.
As you feel the maximum stretch, exhale and lift up the upper part of your torso trying to bring your shoulders to the waist.
Reach the maximum contraction of the abs, hold this position for 2-5 seconds and slowly return to the starting position.
Don't bring your elbows forward and don't hold your arms behind your head. Thus, it will be easier to do exercise
If the exercise is too easy, you can hold a barbell plate or a dumbbell over your head
To keep your neck stationary, imagine that you are holding a small ball with your chin.
