Frog Kicks

[Qomplainerz]

1. Sit on the floor with your legs slightly bent to the knees. 
2. Put your hands on the floor to your side and a bit behind you. 
Fingers looking forward. 
Lean back and balancing on your pelvis raise your bent legs. 
Now move your knees to your chest. 
Straighten your legs again without putting your heels on the floor.
If you can, do 4 sets of 50 repetations.
