My back was in very good condition up until november 2004, I used to do a lot of yoga and other stretching as well as tai boxing/dynamic tensions.
My problems started when I was bench pressing 200lbs and I truggled and pushed with my feet, the key to a healthy back is to work with your whole body and not abuse it, also to do specific exercises to strengthen and also make your back and other muscles supple.
Starting the day with a hot back and then some dancing and stretching for me is perfect!
Good luck to everyone with back problems and the also the riding, if anyone wants more info about my back exercises and system of keeping my back happy, just email me!
Hope everyone reading this has a good weekend, ridefree!
