it is important to remember mechanics.
- Comfortable shoes. Insoles loose cushion over time, and good support is key for footwear.
- posture is your friend. Leaning forward begins to exponentially load your lower back. Play in a mirror, watch your head, shoulders, back, and pelvis. Head up, shoulders back, back straight, pelvis forward (or rether… not back. Pelvic tilt develops easy with our sitting society). That being said, it is good to shift around a bit to relax muscle groups.
- imho a balanced bass is more important than a light one. If you have neck dive, consider lightweight tuners.
- people fuss about 7-8lbs basses over a 10lbs bass then fail to consider their midrange. And i mean tummy. A big tummy pushes your bass away from the centre axis… adding more lateral load to the spine vs one close to your central axis. The belly itself is also is weight out in front which loads you lower back more… and your spine, knees, feet, etc.
- core strength is pretty key. As are your traps.
- fitness outside bass playing is key. Strength training is good, but cardio is really king.
- and maybe this is of no help, but prevention is always key for the back. Some injuries once there, are just there. Our backs are just one of a long list of wear and tear parts… but we always do better doing what we can to prevent serious injury.
