The mechanics behind joint protection and compression
Using joint supports isn't about being weak, it's about being smart. In functional fitness, we put our joints through repetitive and heavy loads. The right equipment acts as an extra, external tendon that stabilizes the joint, increases local blood circulation, and lets your nervous system know it's safe to push with maximum force.
Wrist Wraps
When you catch a heavy clean or jerk/snatch, your wrist bends backward under great pressure. Wrist wraps prevent your wrist from reaching extreme positions.
Cotton Swaddle (Fabric) vs. Elastic (Velcro)
Elastic wraps with Velcro: Perfect for max lifts in bench press or deadlifts. You wrap them rock hard for total restriction of movement before the lift, and tighten them immediately afterwards.
Fabric Wraps (Lace-Up): A CF favorite! These wrap once and then tighten or loosen with a simple twist of the fabric. They are flexible and superior in WODs where you quickly go from barbell to gymnastics.
Knee Sleeves
Neoprene knee braces have two main functions: heat and compression. The heat keeps the synovial fluid supple and the muscles elastic, while the compression provides a slight "rebound" at the bottom of a squat and ensures that the kneecap moves in the correct path.
What thickness should you choose?
- 3 mm: Only for light running or extremely light mobility.
- 5mm: The all-round thickness. Perfect for CF and WODs. Provides good support but is flexible enough to run and jump in.
- 7 mm: For the heavy lifters. The first choice of weightlifters and powerlifters for maximum support in heavy bends.
Frequently Asked Questions & Answers
How tight should I wrap my wrist wraps?
For a 1RM lift, they should be tight enough to feel like a solid cast around your wrist – you should barely be able to bend your hand back. For a longer WOD, they should be looser so as not to cut off blood flow and pump out your forearms. That’s why quick-release fabric wraps are so popular in the box.
Can I wear knee pads during the entire workout?
Absolutely. 5mm pads are designed specifically to be comfortable throughout a full workout, from warm-up to cool-down. If you're using 7mm competition pads (especially if you've gone down a size for extra compression), you may need to pull them down to your calves between sets to rest your joint.
Do knee pads help if I have knee pain?
Knee pads warm the joint and provide stability, which often significantly reduces pain from overexertion and training soreness. However, they are not a cure for actual injuries. If you have persistent sharp pain, you should always consult a physiotherapist to correct your technique, but as a preventive measure, pads are unbeatable.
