Stand in the shallow area with both legs and arms straight together.
Jump and open both your legs and arms together, or alternatively as shown in the second image, then jump to close again. Keep both your legs and arms straight.
Inhale when you open your arms. Exhale when you close. That is because your lungs expand when you open your arms.
Feel your inner thigh and outer thigh muscles as you open and close your legs. Your deltoid and your lat muscles as you open and close your arms.
Before performing this exercise warm up by simple sidewalks for 3 minutes. Gradually increase the speed. After warming up perform this exercise for 3 minutes with both arms together then switch for another 3 minutes with arms and legs alternatively. Stop and stretch for 1 minute then repeat again 2 more times.
