Why You Need Knee Sleeves for CrossFit 

CrossFit workouts can place a lot of stress on your knees due to the volume of high-impact exercises like box jumps, lunges, and burpees. Knee sleeves are essential gear for any serious CrossFit athlete. Here are some of the main benefits of wearing knee sleeves for CrossFit: 

Protect Your Knees from Impact

Impact during high-intensity interval training can lead to pain, swelling, and injury over time. Knee sleeves absorb shock and provide cushioning to protect your knees from the impact of exercises like box jumps, lunges, and double-unders. This allows you to push through tough WODs with confidence, knowing your knees are supported. 

Reduce Knee Pain

Knee sleeves apply compression to provide warmth, improve circulation, and relieve pressure on your joints. This can help reduce pain from chronic knee conditions like arthritis, tendonitis, or inflammation. The snug, insulating fit of knee sleeves helps ease discomfort from old knee injuries. For many CrossFit athletes, knee sleeves make the difference between suffering through a workout in pain or enjoying a workout pain-free. 

Improve Performance 

When your knees feel supported and pain-free, you can focus on performing at your best during each WOD. Studies show that knee sleeves may even provide a slight “spring-like” effect that helps you squat more weight. The compression also helps stimulate your muscles and keeps them warm throughout long, intense workouts. 

Increase Stability

Knee sleeves wrap snugly around your joints to provide stability and help keep everything aligned properly during exercise. This is especially important when performing Olympic lifts like squats, cleans, and snatches with heavy weights.

Knee sleeves reduce wobble and keep your knees tracking properly over your ankles for better form and less risk of injury. For CrossFit athletes, stable knees mean more confidence to push your limits. 

How to Choose the Right Knee Sleeves

With so many knee sleeve options available, it can be difficult to determine which ones are right for CrossFit. Here are some tips for choosing knee sleeves that will provide maximum support and performance for high-intensity workouts: 

Consider the Thickness

Thicker knee sleeves, in the range of 5mm to 7mm, are typically best for CrossFit. The 7mm thickness provides the most robust support for lifting heavy weights and high-impact exercises. However, some people find 5mm or 6mm knee sleeves offer enough support while still maintaining good flexibility. Ultimately, choose a thickness that gives you the confidence to push hard while still feeling comfortable. 

Get the Right Fit

Knee sleeves should fit snugly but still comfortably without cutting off circulation. They should not slide or bunch behind your knees during exercise. Measure around your knee joint to determine your size and consider any swelling that occurs during workouts. 

It is best to choose knee sleeves that provide light to moderate compression. For CrossFit, you want maximum support with a full range of motion, so avoid knee sleeves that are too tight or loose. 

High-Quality, Durable Materials 

Look for knee sleeves made of neoprene, a durable, flexible, and water-resistant material. Neoprene provides insulation, compression, and longevity. Some knee sleeves also incorporate latex or silicone grips and reinforced stitching for added support and to prevent slipping. 

For CrossFit, knee sleeves must be very durable to withstand high-intensity exercise and frequent use. Avoid cheaper sleeves that will wear out quickly. 

Designed for Exercise

Choose knee sleeves intended explicitly for athletic use and high-impact exercise. Knee sleeves for arthritis or injury rehabilitation typically do not provide enough support for CrossFit. 

Look for knee sleeves marketed to weightlifters, powerlifters, and functional fitness athletes. These are designed to handle the demands of strength and endurance training with features like non-slip grips, flexible yet durable materials, and a snug, ergonomic fit. For the best performance, choose knee sleeves purpose-built for exercise. 

When to Wear Your Knee Sleeves 

Knee sleeves are especially useful during high-intensity CrossFit workouts or heavy lifts that place extra stress on your knees. Here are some times when you will want to wear your knee sleeves for CrossFit:

During High-Impact WODs

Anytime your workout includes lots of box jumps, lunges, burpees, or other exercises that pound your knees, knee sleeves are a must. They help absorb shock, provide cushioning, and prevent overuse pain from the impact. Knee sleeves give you the confidence to go all-out during high-intensity intervals without worry. 

When Lifting Heavy 

Knee sleeves are essential for joint support and stability when performing major lifts like squats, deadlifts, cleans, and snatches. They keep your knees warm and compressed while helping ensure proper form and alignment under heavy loads. 

Knee sleeves may even allow you to lift slightly more weight due to the “spring-like” effect and stimulation of your muscles. For any CrossFit workout focusing on maximum lifts, knee sleeves are strongly recommended. 

If You Have Knee Pain

If your knees ache from chronic conditions like arthritis or tendonitis, or from an old injury, knee sleeves can help relieve discomfort during exercise. The compression and warmth of knee sleeves help reduce pain and allow you to complete tough WODs with less suffering. 

Be sure to talk to your doctor about appropriate exercises and modifications based on your condition. Knee sleeves can aid in pain management but should not be used in place of proper rest, recovery, and medical advice. 

For Recovery

In addition to wearing knee sleeves during your workout, you can also use them afterward to speed up recovery. The compression helps reduce swelling in your knees from high-impact exercise. Knee sleeves also provide warmth and support for sore joints after an intense CrossFit session. 

For some people, knee sleeves offer relief from knee pain that sets in a day or two after an especially tough workout. Wearing knee sleeves regularly, both during exercise and recovery, may help prevent delayed onset muscle soreness in your knees.

How to Care for Your Knee Sleeves

To keep your knee sleeves in good condition and provide maximum support for your workouts, proper care and maintenance is essential. Here are some tips for caring for your knee sleeves: 

Hand Wash and Air Dry

Knee sleeves should be hand-washed in cold water using a mild detergent. Gently agitate and rinse them thoroughly to remove all detergent residue. Avoid machine washing knee sleeves, which can cause damage. 

Air-drying knee sleeves away from direct heat is best. Do not machine dry. The air-drying process may cause knee sleeves to stiffen slightly, but they will soften again with use. Air drying helps knee sleeves retain their shape and compression over time. 

Soak to Remove Odors

If your knee sleeves develop stubborn odors from frequent use, soak them in a solution of water and white vinegar before washing as usual. The vinegar helps deodorize the material and kill any bacteria. Be sure to rinse them well after soaking to remove all vinegar before air drying. 

With regular care, knee sleeves can go many months without developing odors. Still, for heavy use, the occasional vinegar soak may be needed. 

Inspect and Replace as Needed 

Check your knee sleeves regularly for signs of wear and tear, like holes, thinning fabric, or damaged seams. Replace knee sleeves at the first sign of damage to ensure maximum support and avoid injury. Generally, high-quality knee sleeves will last 6-12 months with regular use 3-4 times per week. It is best to replace knee sleeves once yearly, even if there are no visible signs of damage, to maintain good support. 

Remove After Exercise

While knee sleeves provide relief from knee pain during activity and recovery, they should not be worn continuously throughout the day and night. Remove your knee sleeves after exercising to avoid discomfort, irritation, or skin problems from extended use. 

Your knees need time without compression each day to maintain healthy circulation. Only wear knee sleeves during exercise, recovery, and any other short periods when you need extra support or pain relief. For chronic knee conditions, you may need to wear knee sleeves for more extended periods, but be sure to consult your doctor for guidance. 

In Conclusion

Knee sleeves provide essential support and protection for CrossFit athletes during high-intensity workouts. They help absorb impact from exercises like box jumps and burpees, reduce pain from chronic knee conditions, and allow you to lift heavier weights with confidence.

Wear your knee sleeves during workouts that place extra stress on your knees, when lifting heavy loads, or if you have knee pain. Remove knee sleeves after exercise, and properly care for them to extend longevity. 

While knee sleeves aid performance and recovery, they should supplement your training rather than become a crutch for your knees. Maintain natural joint mobility and strength by exercising without knee sleeves regularly. Only use knee sleeves when the additional support and protection they provide is genuinely needed for high-intensity intervals or maximum lifts. 

By following these guidelines, knee sleeves can help keep you doing what you love – crushing WODs and pushing your limits – for the long haul. Your knees will thank you!
