Move Better, Feel Better: The Evidence-Based Guide to Exercise for Osteoarthritis

on

If you live with osteoarthritis (OA), the idea of exercise might seem counterintuitive. Won't moving a painful joint just make it worse? The clear answer from decades of research is a resounding NO.

In fact, exercise is not just safe; it is overwhelmingly considered the most effective non-drug treatment for reducing pain, improving physical function, and enhancing the overall quality of life for people with hip and knee OA.

Here is an evidence-based breakdown of the best exercises to include in your routine, backed by comprehensive clinical research.   

1. Strengthening Exercises: Building Your Joint's Support System

Weak muscles around an arthritic joint can increase stress on the cartilage. Strengthening exercises build a protective "brace" of muscle around the joint, leading to improved stability and reduced pain.

The Evidence

Multiple randomized controlled trials (RCTs) confirm that strengthening exercises can reduce pain and improve function in patients with knee and hip OA. By increasing muscle strength, particularly in the lower limbs, you can better absorb shock and improve joint stability. 

  • A recent analysis focused on knee OA strengthening suggested that isokinetic exercise (performed with a machine that maintains a constant speed) may be the most effective type for pain, function, and muscle strength, while isometric exercise (holding a contraction without moving the joint) ranked highest for improving quality of life.

Best Strengthening Choices

  • Resistance Training: Use body weight, resistance bands, light free weights, or weight machines.

    • Quad Sets (Isometric): Tightening the thigh muscle (quadriceps) while the leg is straight.

    • Straight Leg Raises: Lifting a straight leg while sitting or lying down.

    • Mini-Squats/Chair Stands: Performing a shallow squat or standing up from a chair to strengthen glutes and quads.

  • Focus Areas: Targeting the muscles that support the affected joint is crucial, such as the quadriceps, hamstrings, and hip abductors/extensors. 


2. The Power of Aerobic Exercise: The Frontline Treatment

Aerobic exercise—often called "cardio"—gets your heart pumping and is consistently ranked by major studies as the most beneficial exercise modality for managing knee OA, and a key component for hip OA.

The Evidence

A comprehensive systematic review and network meta-analysis published in The BMJ found that, among various types of exercise, aerobic exercise showed the highest probability of being the best treatment for improving:  





  • Pain Relief: Significant reduction in short and mid-term pain.

  • Physical Function: Notable improvements across short, mid, and long-term follow-up.

  • Quality of Life: Enhanced well-being.

The review suggests that aerobic exercise should be considered a first-line intervention for knee OA.

Best Low-Impact Aerobic Choices

The goal is to move without excessive impact or jarring the joints.

  • 🚶 Walking: Simple, accessible, and highly researched. Walking is safe, effective, and improves circulation, builds supporting muscle tone, and helps with weight management.

  • 🚲 Cycling: Using a stationary or recumbent bike offers excellent cardiovascular benefits while keeping joint stress low.

  • 🏊 Aquatic Exercise (Water Aerobics/Swimming): The buoyancy of the water relieves the pressure of body weight on affected joints (especially hips and knees) while providing resistance for muscle strengthening. This is an excellent alternative if land-based weight-bearing activities are not well-tolerated.

3. Complementary Exercises: Flexibility, Balance, and Mind-Body

While aerobic and strengthening exercises are paramount, a holistic program should also include movement to maintain joint range of motion and improve balance.

The Evidence

  • Flexibility and Range of Motion: Studies show that gentle stretching and range-of-motion exercises help maintain or improve joint flexibility, which is essential for reducing stiffness.

  • Mind-Body: Moderate-certainty evidence suggests that mind-body exercises, like Tai Chi or Yoga, can lead to a large increase in short-term function and overall quality of life. Tai Chi, in particular, has been shown to reduce pain, improve balance, and enhance aerobic capacity. 



Best Complementary Choices

  • Range-of-Motion Exercises: Gentle, slow movements to move the joint through its full available arc (e.g., knee bends, ankle circles, shoulder rolls).

  • Yoga or Tai Chi: These ancient practices combine slow, mindful movement with balance and deep breathing.

  • Stretching: Focus on tight muscle groups, holding gentle stretches for 30 seconds after muscles are warm.

Start Slow and Listen to Your Body

While exercise is immensely beneficial, a few key guidelines based on clinical advice should always be followed:

  1. Consult Your Healthcare Team: Always discuss your exercise plan with your doctor or physical therapist. They can help design a safe and effective regimen tailored to your specific joint involvement and severity.

  2. Go Low-Impact: Focus on activities that minimize stress on the joints, like those listed above. Avoid high-impact activities like running or jumping unless specifically advised by a professional.

  3. Warm-up and Cool-down: Begin with 5-10 minutes of gentle range-of-motion exercises to warm up the joints, and end with stretches to cool down.

  4. Listen to Pain: A little muscle soreness after exercise is normal, but sharp or increasing joint pain is a signal to stop and rest. Exercise intelligently. 



The Bottom Line

Exercise is not an option it is a mandatory and highly effective part of your osteoarthritis management plan. By prioritizing low-impact aerobic activities, consistently building muscle strength, and maintaining flexibility, you can significantly reduce pain, reclaim mobility, and greatly improve your daily life.
