Dolor de rodilla can stop you in your tracks—literally. It can be frustrating when simple things like walking the dog, taking the stairs or enjoying your favorite workout suddenly feel uncomfortable or out of reach. However, most knee pain can be improved, and often, the key isn’t more rest, it’s actually more movement.

While it’s tempting to take it easy when knee pain flares up, gentle motion and strength training are often better long-term solutions. Knowing how to strengthen knees with the right exercises can help stabilize the joint, support surrounding muscles and restore flexibility.

Living with knee pain  

The knee is the largest joint in the human body, built to bear weight and keep us moving through life. With every step, jump and twist, your knees take on a tremendous workload. Because our knees do so much, even small imbalances, like weak muscles, poor posture, carrying extra weight in our bodies or improper form during exercise, can add up.

According to the American Academy of Family Physicians, about one in four adults experiences frequent knee pain, leading to millions of doctor visits each year.

Common causes of knee pain

Knee pain can develop for a variety of reasons, from sudden injuries and Artritis to gradual wear over time. Understanding what’s behind your knee pain is the first step toward managing it. For many people, building muscle strength, particularly in your legs and core, can provide the stability and support needed to reduce pain and prevent further injury.

Some of the most common causes of knee pain include:

  • Overuse or repetitive stress: High-impact activities like running or jumping can irritate tendons and cartilage around the knee.
  • Osteoartritis: Age-related wear and tear is one of the leading causes of chronic knee pain, especially among adults over 50.
  • Injury or trauma: Sprains, ligament tears (such as an ACL tear) or meniscus injuries can cause lasting discomfort.
  • Muscle weakness or imbalance: When the muscles around your knees, hips or thighs aren’t strong enough to support proper alignment, extra pressure is placed on the joint.
  • Inflammation or underlying conditions: Bursitis, tendinitis or conditions like rheumatoid arthritis can also contribute to persistent knee pain.

5 Ejercicios de entrenamiento de fuerza para el dolor de rodilla

Before you start any exercise plan, it’s important to first talk with your healthcare provider, orthopedist or physical therapist, especially if your pain is the result of an injury or severe. Once you’ve been cleared to move, focusing on low-impact strength exercises can make a big difference.

The following five moves are designed to strengthen the muscles that support the knee, improve flexibility and keep you moving with less pain and greater confidence. These should be practiced four to five days a week, for six weeks. For each exercise, perform three sets of 8-15 repetitions, and rest for 15-30 seconds between each set.
