Some Exercise Better than None


Study participants were placed in one of five quintiles of gait speed and function and followed for 2 years. Those engaging in 45 minutes a week or more of moderate to vigorous activity (highest quintile) saw significant improvement in knee and hip pain (34-38% better). These findings were independent of sex, BMI, and age. This is less stringent than the U.S. federal government recommendation of 150 minutes per week.

PositiveTip: If you have lower limb joint problems you should begin by engaging in 45+ minutes per week of moderate to vigorous exercise.
