Flexibility
GCaD CYMRU NGfL
The range of movement in a joint.
To improve flexibility you should stretch
the muscles around the joint and hold the
stretch for at least 8 – 10 seconds.
This is called STATIC STRETCH.
It can be active or passive.
- A gymnast shows flexibility when performing the splits.
- A hooker needs flexibility in his shoulders when performing in the scrum.

Body composition
GCaD CYMRU NGfL
The percentage of fat, muscle
and bone in the body.
You could be the right weight but still not fit
because you have a lot of fat and small,
weak muscles. Body composition gives a
better idea of fitness and it specifies what
percentage of your body weight is fat.
