Yeah, yeah, 5BX is great! While a certain rare exercise machine gives the most relief, one simple 5BX back exercise (chart 1, exercise 3) is as effective, provided I do it regularly. I do other exercises too: stationary cycling, rowing and treadmill with some weight work. All necessary because I enjoy food!
