4 Knee Stretches and 7 Strengthening Exercises to Decrease Pain

If your knees are giving you problems, and you feel like the Tin Man from "The Wizard of Oz" when getting out of bed, rest assure that at least you’re not alone. In fact, nearly 50 million Americans feel the exact same way.

Knees are the most commonly injured joints in the body. Considering that when you simply walk up stairs, the pressure across your knee joints is four times your body weight, it isn't surprising. Simple, everyday wear and tear can end up hurting your mobility.

But it’s not too late. Like a rusty door hinge, with care and maintenance, your knees can be trouble free. Even if you already experience problems, exercising and strengthening the muscles surrounding the knee joints— quadriceps (front of thigh), hamstrings (back of thigh), abductor (outside thigh), and adductor (inside thigh)—will help make your knees stronger and less susceptible to injury. Exercise keeps your joints from stiffening and provides needed support, making movement easier and reducing pain.

Knee Stretches

  1. Chair knee extension: Sitting in a chair, rest your foot on another chair so the knee is slightly raised. Gently push the raised knee toward the floor using only leg muscles. Hold for 5 - 10 seconds and release. Repeat 5 times on each leg.
  2. Heel slide knee extension: Lie on your back, with left knee bent and left foot flat on floor. Slowly slide the left heel away from your body so both legs are parallel. Hold for 5-10 seconds, return to starting position. Repeat 5 times on each leg.
  3. Knee flexion: Sitting in a chair, loop a long towel under your foot (resting on the floor). Gently pull on the towel with both hands to bend the knee, raising your foot 4 - 5 inches off the floor. Hold for 5 - 10 seconds, then release. Repeat 5 times on each leg.
  4. Hamstring stretch: Standing, put one foot in front of you, toes up. With hands on the small of your back (or one hand holding a chair for balance), bend the opposite knee and hip (not your lower back), until you feel the hamstrings stretch. The upper body comes forward at the hip. Hold for 5 -10 seconds, then release. Repeat 5 times on each leg.

Knee Strengthening Exercises

  1. Wall slide: Leaning with your back against a wall, bend your knees 30°, sliding down the wall, then straighten up again. Move slowly and smoothly, using your hands on the wall for balance. Keep feet and legs parallel, and do not allow knees to go out over the toes. Repeat 5 -10 times.
  2. Bent-Leg Raises: Sitting in a chair, straighten one leg in the air (without locking the knee). Hold for about one minute. Bend your knee to lower the leg about halfway to the floor. Hold for 30 seconds. Return to starting position. Work up to 4 reps on each leg.
  3. Straight-Leg Raises: Sitting in a chair, rest your foot on another chair. Lift the foot a few inches off the chair while keeping your leg straight. Hold for 5 -10 seconds. Return to resting position. Repeat 5 -10 times. (Also work on increasing the time, up to 2-3 minutes if possible.)
  4. Abductor Raise: Lie on your side, propped on one elbow. The leg on the floor bent, the other straight. Slowly lift the top leg, hold for 5 -10 seconds, then lower. (Ankle weights will increase the intensity). Do 1-3 sets with 12-15 repetitions each. Remember to rest in between sets.
  5. Hamstring Curl: Stand with the front of your thighs against a surface (a table or wall). Flex one knee up as far as is comfortable. Hold for 5 - 10 seconds, then lower slowly. If possible, do not touch the floor between repetitions. (Ankle weights will increase the intensity.) Do 1-3 sets with 12-15 repetitions each. Remember to rest in between sets.
  6. Step-Ups: Stand in front of a step, like a sturdy bench or stairs, about two feet high (or less if necessary). Step up onto the support, straighten your knees fully (without locking them) and step down. Maintain a steady pace. If you are comfortable with your balance, pump your arms while doing this exercise. Start with 1 minute, slowly building your time. Gets your heart pumping too!
  7. Stationary Bike: Biking is a good way to increase strength and range of motion. Make sure you have the right positioning of the legs. At the bottom of the pedal stroke, the bend in the knee should be 15 degrees. Start with 10 minutes and slowly increase your time.
Depending on your current level of activity and mobility, a good start is three stretching and three strengthening exercises, three to four times a week. Stretching can be (and should be) done everyday to prevent stiffness and achy joints. These stretches can even be done a few times a day, if needed.

Always check with your doctor before beginning an exercise program. These exercises are designed to help, not hurt. If you experience pain at any time during the exercise, stop. Pain is your body’s way of telling you that something is wrong.


If you have increased soreness after doing these exercises, it may help to ice your knee or knees for 10 to 20 minutes. Place a bag of ice (or frozen vegetables) over the joint, with a towel between to protect the skin. Elevate your leg on a chair if ice alone is inadequate.

Remember to include regular cardiovascular (aerobic) exercise as part of a well-rounded routine. Research shows that this type of exercise helps increase pain tolerance.

Thanks for the tips. Actually, I prefer natural therapy to heal injuries instead of taking drugs. Report
Always looking foe new ideas, Thanks! Report
I spent time in physical therapy years ago because of a torn rotator cuff, and while I was there I saw a lot of people recovering from knee injuries. The most common exercise I saw them do was to stand on one foot and throw a ball at something and catch it when it bounced back.

I read an article in Men's Health magazine about how to reduce the likelihood of knee injury by doing what they called the "alphabet exercise," which consisted of standing on one foot while drawing the letters of the alphabet with the other. The author said this strengthened the muscles that stabilize the knee, and that in turn better protects the knee.

In both cases the object of the exercise seems to be to stand on one leg while moving either the other leg or the upper body, so that the muscles of the support leg are constantly having to work to keep the knee stable.

So I came up with my own version, that I add to my martial art exercises. I stand on one leg and do really slow kicks with the other leg (this is a great deal harder than doing fast kicks, but I also do these too). I also stand on one leg and practice hand techniques, usually full speed. I can do these while watching TV, washing dishes, and combined with various other things. Sometimes I use a cane for balance (though that isn't as necessary anymore), but I don't put any more weight than necessary on the cane.

I had serious pain in one knee awhile back, so bad I was walking down stairs one step at a time very slowly (and painfully) and I was using a cane to walk. I thought it must be an injury; ignoring it didn't make it go away so I finally saw an orthopaedic doctor. He took an xray, and said I had serious arthritis in that knee (most likely because of the way I earned a living for 30 years). He recommended physical therapy and an anti-inflammatory drug.

Being the cheapskate that I am (and a do-it-yourselfer)
, I looked into anti-inflammatory foods, and increased my consumption of them instead of taking the drug. And instead of PT I did the knee exercise I described abov... Report
Thank you for the exercise, would like to see some photos. : )
Wonderful exercises, very helpful, thanks. Report
Great tips! Report
13 steps to walk, 2x daily (at least); I have learned walking down them backwards (carefully + hand on rail) helps my lower back and my knees, too. Report
Great article! Report
Great tips Report
Just in time. Very informative. Report
Thanks for the information! Report
Good set Report
Thank you for this article. I have been looking for exercises to help my knee. I have to have one replaced and until I do, I need some exercises that will help stabilize it.
I'll try these. Nothing else has stopped the pain. Report
