Movements bad for knees often involve high impact, deep bending, twisting on weight-bearing, or repetitive strain, such as jumping, deep squats, lunges past 90 degrees, quick pivots, and kneeling for long periods, especially with poor form or existing weakness, which can overload cartilage and ligaments, causing wear or injury.
Bending your knees past 90 degrees adds pressure across the cartilage toward the front of your knee as well as your menisci – which can lead to pain or long-term wear. “If you have knee issues, avoid letting your knees go past your toes,” says Dr. Rios. “Stick to shallower squats or reverse lunges for better control.
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.
For pregnancy knee pain, focus on low-impact exercises like swimming, stationary cycling, and prenatal yoga to strengthen supporting muscles without joint stress, plus gentle stretches like leg lifts and torso rotations, always getting doctor approval and avoiding overstretching due to the hormone relaxin. Strengthening quads and hamstrings, using heat/ice, wearing supportive belts, and elevating legs also provide relief, according to hingehealth.
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.
Symptoms
Squatting correctly should not cause knee pain. However, people who squat incorrectly and those with a knee injury or knee condition may experience knee pain when squatting. Many people squat regularly as part of their workout routine or during everyday tasks.
If you're dealing with a fresh knee injury—especially one with knee swelling or sharp pain—it's important to give your knee a break. Rest doesn't mean total inactivity, though. It just means avoiding high-impact movements or weight-bearing exercises for a few days.
To achieve and maintain a reasonable level of fitness aim for one of the following: a session of moderate-intensity exercise on all or most days of the week. at least 150 minutes of exercise over a week. 10,000 steps per day.
Vitamin D deficiency is linked to knee pain. Adequate nutrition is essential for maintaining healthy knees. Knee pain can be managed and prevented through dietary adjustments. Understanding the link between nutrition and knee health is critical.
Adjust your sleeping position
Sometimes knee pain at night has less to do with your knee and more to do with how your body is positioned. “If you sleep on your side, place a pillow between your knees to reduce pressure on your joints,” says Dr. Burns.
The most common cause of knee pain can hit you in your 30s as easily as it can in your 60s and 70s. Osteoarthritis, or “wear-and-tear arthritis,” is the most common cause of knee pain – and the most common form of arthritis.
High-impact sports that require a lot of jumping or other repetitive impacts put a lot of stress and strain on your knee joints, particularly the cartilage that lines your joints. Over time, these activities can lead to painful knee arthritis.
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.
For those dealing with meniscal knee pain, lunges can be a more knee-friendly option compared to deep squats. Lunges involve less knee flexion and provide better control over the range of motion.
Here are seven simple ways to keep your joints lubricated as you get older.

For patients with knee osteoarthritis, aerobic activities such as walking, cycling, or swimming are likely to be the best exercise for improving pain, function, gait performance, and quality of life, finds a study published by The BMJ today.
Deep knee bending with squats can be uncomfortable or painful for people with certain conditions. These conditions include knee osteoarthritis, runner's knee, and meniscus tears.
Here are some key supplements you may want to consider adding to your health regimen to relieve joint pain.
According to Dr. Sushil Kumar, Consultant Orthopedics at Kailash Hospital, Dehradun, “Vitamin D deficiency can lead to weakened bones and joint pain, including in the knees. Identifying and addressing this deficiency can significantly improve symptoms.
Patients with knee osteoarthritis will experience the following symptoms: pain in the knee, freezing or stiffness in the joint, a loud clicking sound coming from the joint, pain when touching a certain area of the knee, or joint deformities, although each patient's combination of symptoms will be unique.
If you suspect you have knee instability after performing these tests, you should follow up with your regenerative medicine physician for further evaluation.
