Exercises for your
biceps.
|
 |
- Accelerate the rotor
and hold the Powerball upwards as you see it in the
picture.
- You will feel how the
muscles in your upper arm start working.
- These exercises are
good for all sports where a strong biceps is important:
e.g. rock-climbing, tennis, rowing, and many others.

The harder you
work
it,
the heavier
it
gets! |
