Flexibility is an important part of a child’s fitness and includes movements like bending, twisting and stretching. These activities allow the muscles and joints to move easily through their full range of motion. Range of motion refers to the full movement potential of a joint such as its range of flexion and extension, or how far you can move your limbs without straining. Large body movements are critical to promote flexibility. Examples of large body movements include: climbing a slide, tumbling, swinging and hanging from bars (Note: while a child using his/her own weight to hang on the monkey bars is safe, swinging or twirling a child by their arms is not safe).
