Breaking Down The Single Leg Squat    "Single-leg squats allow you to target the legs with greatly reduced shearing forces on the spine. Moreover, the overall external loads used for single-leg squats are typically less than with bilateral lifts, so there are fewer compressive forces, making them much more low-back friendly than their bilateral counterparts.

This is obviously appealing for back-pain sufferers, but also healthy back populations, too. One study revealed that in a random sample of 98 "healthy" asymptomatic backs, 64% of the subjects had a disk abnormality of some sort.

Also worth noting is that while the overall prevalence of disc abnormalities didn't change much with physical activity, the prevalence of disc protrusions at L5-S1 was higher in people that exercised regularly as compared to more sedentary folks (16% to 4%). Remember, these were asymptomatic subjects, so just because you're not currently experiencing back pain doesn't mean that your spine is necessarily healthy.
