Although increasing back muscle strength is a popular objective of low back rehabilitation, studies have not been able to support this concept.
Studies of Leino (1987), Biering-Sorensen (1984), Holmstrom and Moritz (1992) and others demonstrate that:
1. No type of back muscles strength training can be preventative or curative for lower back injuries.
2. Most people have back muscle strength but hip and leg muscles weakness, this is why most people lift with their back muscles thus damaging their spinal discs.
3. Creating back endurance is the only training that when combined with hip strength, power and flexibility plus good posture and right lifting mechanics, is effective in treating and preventing back pain and dysfunction.
