As a runner, I know the importance of a strong lower body. Without my weekly leg workout I find I'm more susceptible to knee pain, muscle injuries and other horrible aches that hold me back.
This doesn't just apply to running either. Developing your leg muscles can boost your balance, mobility and posture, not to mention the benefits it gives you for day to day activities such as walking, climbing stairs and lifting heavy objects. The bottom line: a strong lower body is a good thing.
