Training for the
grip of the fingers.
|
 |
- Hold the Powerball
with the tip of your fingers only.
- Thus you exercise the
muscles in your fingers without risking any
over-exercising.
- This is because the
rotor gets slower and the forces decrease as soon as you
give in and reduce the power you put in.
- This is very good
training for rock climbers, mountain bikers or piano
players.

The harder you
work
it,

gets! |
