What Is VMO Exercises?
The Vastus Medialis Obliquus (VMO) muscle is a crucial part of the quadriceps group located on the inner side of the thigh. It helps stabilise the patella (kneecap) during activities like walking, running, and squatting. The VMO helps maintain the patella's alignment within the femoral groove during knee movements, counteracting lateral forces that could lead to improper tracking or excessive stress on the patellofemoral joint.
Targeted VMO exercises are essential for strengthening and enhancing the functionality of this muscle. These exercises focus on isolating and challenging the VMO to promote its activation and development. Regular practice of VMO exercises leads to muscle hypertrophy and neural adaptations, optimising the muscle's recruitment patterns. This results in improved knee stability and a reduced risk of injuries.
Strengthening the VMO also helps correct muscle imbalances within the quadriceps group, often linked to knee problems like patellofemoral pain syndrome and patellar tracking disorders. VMO exercises are like compound movement exercises to ensure proper alignment and force distribution around the knee joint by restoring balance among the quadriceps muscles. This scientific rationale highlights the importance of including VMO exercises in rehabilitation programs and injury prevention strategies.
Ultimately, targeting the VMO through specific exercises enhances knee health and performance, reducing the risk of knee-related complications. These exercises are vital for maintaining patellar stability, preventing injuries, and ensuring optimal knee function.

What Causes A Weak VMO?
Weakness in the Vastus Medialis Obliquus (VMO) can arise from various factors supported by scientific reasoning:
Cause | Impact | Scientific Reasoning |
Muscle Imbalance | The VMO works in conjunction with other quadriceps muscles. When there is an imbalance, with the VMO being comparatively weaker, it can lead to issues like knee instability. | This imbalance may result from inadequate strengthening of the VMO relative to the other quadriceps muscles. |
Neuromuscular Control Issues | Efficient muscle activation is essential for strength. Problems with neuromuscular control, like delayed activation or improper firing patterns of the VMO during movement, can contribute to its weakness. | Proper neuromuscular control ensures coordinated muscle contractions. When this is compromised, the VMO may not activate effectively, leading to weakness. |
Sedentary Lifestyle | Lack of physical activity or prolonged inactivity can lead to muscle weakness, including the VMO. | Without regular exercise or even brisk walking and movement, muscles can weaken due to disuse. The VMO, like other muscles, requires regular activation to maintain strength. |
Injury or Trauma | Knee injuries affecting the quadriceps muscles or the patellofemoral joint can weaken the VMO during recovery. | Trauma, such as tears or strains in these muscles, can impair VMO function, as injury recovery often leads to muscle atrophy or improper healing. |
Biomechanical Issues | Poor knee alignment or biomechanics can strain muscles, including the VMO. | Factors like improper foot positioning or abnormal patellar tracking can lead to uneven stress on the VMO, contributing to its weakness. |
Genetic Factors | Some individuals may have genetic predispositions to muscle weakness, including the VMO. | Genetic factors, such as muscle fibre composition and structure, can influence muscle strength and function, potentially leading to a naturally weaker VMO. |
Expert’s Advice
As a dietitian, I often recommend a balanced approach to VMO exercises that go hand in hand with eating well. While focusing on exercises that target the Vastus Medialis Obliquus (VMO) muscle is important, having a healthy diet is just as crucial for keeping muscles strong and aiding recovery. A diet rich in healthy lean proteins, whole grains, healthy fats, and vitamins and minerals provides the required nutrients needed for muscle repair and growth. Drinking enough water is also key for keeping muscles working well and preventing cramps during exercise.
Including whole, nutrient-packed foods like fruits, veggies, whole grains, and lean proteins in your diet gives your body the fuel to get the most out of VMO exercises. Additionally, I often advise against eating too many processed foods, sugary snacks, or foods that can cause inflammation, as these can slow progress.
