With bad knees, avoid high-impact activities (running, jumping), sports with pivoting (basketball, tennis), deep squats/lunges, and activities that jar the joint or involve rapid twisting, while also being cautious with heavy lifting, stairs, and poor footwear, and always listen to your body for pain signals to prevent further damage.
The #1 mistake making bad knees worse is excessive rest and a sedentary lifestyle, leading to weaker supporting muscles, stiffness, and a vicious cycle of more pain; instead, gentle, consistent movement (like walking, swimming) is crucial to strengthen the joint and improve function, though it must be balanced with avoiding activities that cause sharp pain. Other major errors include ignoring pain signals, carrying excess weight, wearing unsupportive shoes, and poor movement patterns, says Parkside Sports Physiotherapy and Coastal Empire Orthopedics.
High-impact exercises can further injure painful knees. Avoid jarring exercises such as running, jumping, and kickboxing. Also avoid doing exercises such as lunges and deep squats that put a lot of stress on your knees. These can worsen pain and, if not done correctly, cause injury.
Here are seven simple ways to keep your joints lubricated as you get older.
Exercises for the knees
Heel Slide
This move takes you through the repetitive motion of bending and straightening your knee. “This helps lubricate the knee joint, so you can better move it through its range of motion,” says Dr. Stewart.
Climbing stairs involves bending and straightening your knees, which can help to improve your joint flexibility. The repetitive motion of stair climbing can contribute to an increased range of motion in the knees for many people, reducing the risk of stiffness or discomfort.
Foods to Avoid
Targeted joint formulas if appropriate.
Consider a reputable product combining glucosamine, chondroitin, MSM, hyaluronic acid, and vitamin C, especially if you have mild osteoarthritis or persistent stiffness.
Oranges are an obvious choice in terms of getting vitamin C to promote the building of collagen as well as to promote cellular healing, which by extension is helpful in cartilage regeneration and protection. Vitamin C is also found in abundant quantities in other foods like kiwis, red peppers, kale, and strawberries.
Here's what some small studies found:
The most common causes of knee pain are related to aging, injury or repeated stress on the knee. Common knee problems include sprained or strained ligaments, cartilage tears, tendonitis and arthritis.
In the person-based analysis, we found that vitamin K deficiency was associated with higher risk of having incident knee osteoarthritis in one or both knees compared with no osteoarthritis developing in either knee, respectively (Table 2).
You should worry about knee pain and see a doctor if you have severe pain after an injury, can't bear weight or move your knee, experience significant swelling/redness/warmth, feel instability (it "gives out"), have a fever, or can't fully bend/straighten it, as these suggest a serious injury like a ligament tear or infection needing prompt care; otherwise, if pain is mild and improves with rest, self-care might suffice, but consult a professional for persistent pain or disrupted daily life.
This makes it easier for oxygen and nutrients to reach your painful joints. Heat helps loosen tight muscles and joints and relieves pain and muscle spasms. If you have swelling, it's best to use ice for 24 hours, then switch to heat. If swelling isn't a problem, it's fine to use heat when you first notice knee pain.
Repetitive use
Like overuse, repetitive use can damage knee cartilage or cause it to wear down more rapidly. Repetitive bending, lifting, squatting, or kneeling can also increase joint inflammation, another factor leading to cartilage damage and wear.
While there's no single "strongest," Omega-3 fatty acids (from fatty fish) and curcumin (from turmeric) are consistently cited as highly potent natural anti-inflammatories, alongside powerful antioxidants from fruits and vegetables like blueberries, plus herbs like ginger and garlic, all working to reduce inflammation pathways. A comprehensive anti-inflammatory diet emphasizes these foods, though Omega-3s and curcumin often stand out for their significant impact.
Animal studies show the injection of magnesium into a knee joint with OA relieves pain and slows down the development of cartilage damage. Research suggests the magnesium promotes the formation of new chondrocytes, which are the specialized cells that produce healthy cartilage.
Vitamin B12 plays a crucial role in maintaining nerve health and reducing inflammation, which makes it beneficial for individuals experiencing joint pain.
Best anti-inflammatory foods for joint pain
While rest is important, if you are living a sedentary lifestyle, meaning you are sitting and resting more than you are being active, you may be seriously affecting the health of your joints and increase your arthritis symptoms.
For severe pain, topical NSAIDs likely won't match the effects of oral meds, but those who have mild to moderate arthritis may find relief. They come in OTC and prescription gels and creams. A Cochrane review found that diclofenac or Voltaren, ibuprofen and ketoprofen gels are the most effective.

As a "low impact" form of exercise, even short bursts of stair climbing can help improve cardiorespiratory fitness and reduce the risk of cardiovascular disease. The improvements in aerobic fitness from climbing stairs at home can even be equivalent to those gained using stair machines at the gym.
