hypermobile

Exhibiting hypermobility; able to move further than usual, as of joints.

If you're hypermobile, meaning you have an increased range of movement in a body part, be careful not to overstretch your joints and avoid repetitive exercises, which can lead to pain.

Excessively mobile.

No. The P.D.A., the cellphone and the computer did not usher in our hypermobile, split-focus, cybercentric culture.
