Knees silently carry us through everyday movements — walking, sitting, climbing stairs — yet we often neglect their care until pain sets in. Experts now warn that early attention can make all the difference in keeping knees strong and healthy for a lifetime.
According to a BBC health report, many people begin experiencing knee pain, swelling or stiffness in their 30s, particularly in the mornings or during seasonal changes.
Doctors explain that walking alone puts 1.5 times the body’s weight on the knees, making them one of the most burdened joints. After back pain, knee pain is the second most common musculoskeletal issue worldwide, often reducing mobility and quality of life.
Key muscles that protect knees
Dr. Anikar Chhabra, an orthopedic surgeon at the Mayo Clinic, US, says the knees rely on four major muscle groups:
-
Hamstrings
-
Hip muscles
-
Quadriceps (front thigh muscles)
-
Calf muscles
Strengthening these muscle groups, he adds, is crucial to protect the knees and improve their durability.
Expert-recommended exercises
Doctors suggest simple home workouts that can be done 3–4 times a week:
Step-Ups
Climb onto a low stool or step, one foot at a time, then return. This strengthens the quadriceps.
Squats
Do 15 squats morning and evening to activate thigh and glute muscles, reducing knee pressure.
Leg Raises
Lie flat, lift one leg straight up a few inches, hold, then lower. This builds stability in the knee muscles.
Calf Raises
Stand on your toes, then lower back down. This exercise improves balance and strengthens calves.
Chair Stands
Sit and stand repeatedly without hand support. This strengthens the legs and core.
Why exercise protects joints
Exercise doesn’t just build muscles — it also improves the internal joint system. Doctors note that movement helps produce synovial fluid, which lubricates the knees, reducing swelling and friction.
Dr. Alexis Colvin of Mount Sinai School of Medicine says these exercises also strengthen bones, reduce osteoporosis risk, and improve balance, especially in older adults.
However, she advises beginners to seek initial guidance from a physiotherapist or trainer. Mild soreness is normal, but severe or worsening pain requires medical consultation.
Prevention is better than cure
Health experts agree: the earlier you start, the stronger your knees will remain. Whether young or middle-aged, investing in knee protection today can ensure an active, independent lifestyle tomorrow.
As Australian filmmaker Baz Luhrmann once said in his song:
“Be gentle with your knees, you will miss them when they leave.”
