I've found over 30 years of playing and teaching that the best exercises for playing bass (and guitar) are to play the instrument. I used to do stuff like the spider, chromatic exercises, etc. But I found that the best way to get better physical control was to simply play music on the bass.

The elastic band exercise described above by Fergie can be done away from the bass, watching TV, on a lunch break, etc, and only takes about 5 or 10 minutes. So no practice time is lost, the exercise is beneficial to the task required of the hand...and it is free.![]()
I agree with John and always will in this matter...But sometimes extra help is needed because playing the bass is the causing the problem or highlighting an underlying problem from some where else. If playing time is tight then exercises away from the bass will help, as also will warm ups and stretches.
Combining the both is the way to go, but always emphisis the playing because that is the ultimate goal. As the OP asked about exercise the elastic band is by far one of the best, it is portable, has soothing qualities, it works on resistance so works with the hand, and of course as fearseol says it is free.
As a footnote..3 years ago i was in a car smash which broke my neck, ultimatley i was paralyzed in the right upper side, suffered nerve and muscle damage. As my hand and arm would not move and muscles were wasting, i "invented" a device using elastic bands to help my hands recover when i started to get some feeling in them. It is a ply board with five elastic bands where my finger would be. Because i was lying on my back i would have the board by my side with my finger in the bands (palm down) and just try and lift them. As i was focusing on a specific task, the fingers got gradually got stronger. this i knew because i could measure anything done against how much i could move the bands and for how long before the hand failed.
Within eight months of the accident i had made enough of a recovery to handle a bass. Specialists that examined me were amazed at how much my hand had recovered consisering the damage done to them. Another technique i used later to help make them stronger was a bucket of sharp sand. I made my hand into a point ( ring and forefinger together, thumb and little finger together underneath, and middle finger on top) pushed it deep into the bucket and opened the hand wide. Took it out and repeated it. The sand created the resistance as the elastic band around the fingers does the same job as the sand, but the elastic band was so much better and so much more portable.
All good exercises are based on the hands and fingers opening or extending, not about pushing down or creating grips.
Below is the device i made, it was made for a purpose because i had no other options. I am still working on the recovery of my hands but it is a slow process due to the nature of the injuries.
