6 Exercises To Strengthen Knees And Improve Mobility

The knee joint is an engineering marvel of the human body, responsible for bearing the weight of our entire frame and enabling smooth movement in various directions. Composed of bones, cartilage, ligaments, and tendons, the knee joint is one of the largest and most complex joints in our body (5). It plays a crucial role in activities such as walking, running, jumping, and even sitting.

However, due to its intricate structure and constant use, it is also prone to injuries and wear-and-tear. An estimated 20% of the global population suffers from knee pain at some point in their lives, making it one of the most common health issues worldwide (6). This prevalence has led to a growing need for effective methods to maintain knee health and prevent further damage.

By including targeted exercises in your fitness routine, you can strengthen the muscles surrounding your knees and improve mobility, thereby reducing the risk of injuries and alleviating discomfort.

How Can I Make My Knees Stronger?

To make your knees stronger, you’ll take a multi-faceted approach focusing on strength and flexibility. 

You’ll need to perform the best exercises to strengthen your knees while also stretching the muscles and ligaments around them. Other solutions such as physical therapy and lifestyle changes may also be necessary for certain conditions.
