Our knees are among the body’s most important joints, yet often the most neglected.
A little effort today can prevent pain, stiffness, and injury later in life. Here are the key facts and exercises for stronger, healthier knees.
Understand why your knees take such a beating
Research shows that even during a simple walk, the force on your knees equals one and a half times your body weight.
Over time, this strain can lead to wear and discomfort, especially if you have a physical job, play sports, or gain weight.

The four muscle groups that protect your knees
The knees rely on four major muscle groups: the hamstrings, glutes, quadriceps, and calves.
When these muscles work together, they provide stability and absorb impact. If they weaken, more stress is placed on the joint, leading to pain.
Strength training prevents cartilage degeneration
Studies show that strengthening these muscles can prevent cartilage breakdown, delaying or even avoiding the need for knee surgery.
In early osteoarthritis, strong muscles can also ease pain and reduce pressure on the joint.

Exercise improves cartilage health
Physical activity stimulates the production of synovial fluid which is the knee’s natural lubricant.
This reduces stiffness and inflammation while helping the cartilage move smoothly and stay healthy.
Strengthening also builds bone density
Some knee exercises help strengthen the bones around the joint, lowering the risk of osteoporosis.
For older adults, this added stability can improve balance and reduce the risk of falls.

Start in your thirties
While much research focuses on older adults, studies show that even teenagers who play sports benefit from early knee strengthening.
Experts recommend starting in your thirties, when muscle mass and bone density begin to decline.
Train for 15 minutes several times a week
Orthopaedic specialists suggest spending about 15 minutes, three to four times a week, on simple at-home exercises that require no special equipment.
This small routine can make a big difference in long-term mobility.

Step-ups for stronger thighs and hamstrings
Use a stair or low step and alternate legs as you step up and down.
This strengthens the quadriceps and hamstrings, helping to reduce kneecap strain that can lead to pain and clicking sensations.
Squats for stability and balance
Bodyweight squats strengthen both the quads and glutes while improving balance.
Short sets of 15 squats every 30 minutes can boost muscle-building proteins and improve quality of life for arthritis patients.

Straight leg raises to protect the joint
Lie on your back with one leg bent and the other straight. Raise the straight leg a few inches, hold, and lower slowly.
This exercise builds quadriceps strength, protects the knee, and helps prevent workout-related injuries.
Calf raises for muscle balance
Stand with your feet shoulder-width apart, lift your heels slowly, hold for a second, and lower again.
This strengthens the calf muscles and helps maintain balance between the muscles supporting your knee.
Get up from a chair to strengthen your core
Sit down and stand up repeatedly without using your arms.
This exercise works the core muscles, which play a crucial role in knee stability. To increase difficulty, use a lower chair or try it one-legged.
Seek guidance and listen to your body
If you’re new to these exercises, consult a physiotherapist to ensure proper form. You can add weights later, but bodyweight is often enough.
Muscle soreness is normal, but joint pain signals a problem that needs medical attention.
