How to Lower the Risk of Knee Injuries During Training

An exercise to strengthen the muscles around the knee — injury prevention

The knee is one of the most vulnerable joints during regular training, especially with age. We break down which habits and exercises actually reduce the risk of injury, and which myths you can safely ignore.

The knee is a complex joint that bears the weight of the body with every step, squat, and jump. With age and without targeted preparation, the risk of discomfort and injury in this area rises, but in most cases it can be reduced through deliberate habits rather than giving up training altogether.

Warming Up Before Exercise

Cold, unwarmed muscles and ligaments absorb load less effectively. 5–10 minutes of light cardio and dynamic stretching before the main workout isn't a formality — it's real injury prevention.

Strengthening the Muscles Around the Knee

The knee itself is a joint between bones, and its stability comes primarily from the thigh and glute muscles. Useful exercises:

bodyweight or lightly loaded squats, with proper technique;
forward and lateral lunges;
glute bridges;
hamstring exercises (leg curls).

Technique Matters More Than Weight

Many knee injuries come not from the exercise itself but from technique mistakes: the knee caving inward during a squat, the foot distributing weight incorrectly, an uncontrolled range of motion. It's better to lower the working weight and perform the movement correctly than to chase progress with poor technique.

Gradual Progression of Load

A sudden increase in training volume or intensity is one of the most common causes of joint injuries, especially in runners. A general rule is to increase training volume by no more than 10% a week.

Recovery After Knee-Heavy Training

After intense leg-focused training, stretching, a foam roller, and localized cooling can help if the joint feels notably tired or mildly swollen. Many people use IceWave patches around the knee area for this, and for a broader recovery effect after exertion, the X49 patch.

Preventing knee injuries rests on three pillars: warming up, strong muscles around the joint, and gradually building up training load. If an injury does happen, read more about recovery in "Recovering From an Injury".

Questions and answers

Why do knees hurt more often after 35–40?

With age, cartilage and ligaments lose elasticity, and the muscles around the joint gradually lose strength without targeted training. This makes the knee more vulnerable to loads that went unnoticed at 20.

Which exercises strengthen the knees?

Squats with proper technique, lunges, glute bridges, and exercises that strengthen the quadriceps and hamstrings. Strong muscles around the joint take on part of the load that would otherwise fall on the ligaments.

Is running dangerous for the knees?

Moderate running with proper technique doesn't wear down the knees on its own — research doesn't support the myth that running "wears out" joints in healthy people. The risk rises with a sudden jump in training load, the wrong shoes, and weak muscles around the joint.
