Voodoo Flossing
Compression band wrapping technique for joint mobility, reducing swelling, and restoring range of motion
Bottom Line
Voodoo flossing (tissue flossing, compression band flossing) is a simple technique that can produce immediate improvements in joint range of motion and reduce localized swelling. The mechanism likely involves a combination of fascial shearing, blood flow occlusion/reperfusion, and neurological effects.
A cheap, effective tool for joint mobility and pre-workout prep. Best for ankles, elbows, wrists, and knees. Not a cure-all, but useful addition to a mobility toolkit.
Science
Proposed mechanisms:
- Fascial shearing: Band compression + movement creates shear forces between tissue layers
- Occlusion/reperfusion: Temporary blood flow restriction followed by hyperemia upon release
- Fluid displacement: Mechanical pressure pushes interstitial fluid and reduces edema
- Neurological: Novel sensory input may reduce pain perception and muscle guarding
- Joint capsule mobilization: Compression alters joint mechanics during movement
Key studies:
- Driller & Overmayer (2017): Floss bands improved ankle dorsiflexion ROM immediately
- Angelopoulos et al. (2021): Shoulder ROM improved after flossing in overhead athletes
- Konrad et al. (2021): Comprehensive scoping review of tissue flossing mechanisms
What the evidence shows:
- Acute ROM improvements: Well-supported
- Swelling reduction: Supported (mechanism similar to lymphatic drainage)
- Pain reduction: Some support, likely neurological
- Performance enhancement: Limited evidence
- Long-term changes: Insufficient data
Effect sizes:
- Ankle ROM: 5-10 degree improvement (immediate)
- Effects duration: 15-45 minutes typically
- Cumulative effects with repeated use: Unclear

View all studies & compare research →Practical Protocol
Basic flossing technique:
- Start wrapping 2-3 inches below the target joint
- Wrap with 50-75% band tension (should be tight but tolerable)
- Overlap each wrap by 50%
- Continue 2-3 inches above the joint
- Secure end by tucking under last wrap
- Perform 10-15 reps of joint movement (flexion/extension, circles)
- Remove band after 2 minutes maximum
- Move joint freely immediately after removal
Joint-specific protocols:
| Joint | Wrap Direction | Movements |
|---|---|---|
| Ankle | Start at mid-foot, wrap up to mid-calf | Dorsiflexion, circles, calf raises |
| Knee | Start below knee, wrap up to lower quad | Squats, lunges, flexion/extension |
| Elbow | Start at forearm, wrap up to bicep | Flexion/extension, pronation/supination |
| Wrist | Start at hand, wrap up to forearm | Flexion/extension, circles |
| Shoulder | Wrap around upper arm/delt | Arm circles, overhead reach, rotation |
Timing:
- Pre-workout: 2-3 minutes per joint for mobility prep
- Post-workout: For swelling reduction
- Between sets: For stubborn mobility restrictions
- Recovery days: As part of mobility work
Common mistakes:
- Wrapping too tight (should be uncomfortable, not painful)
- Leaving on too long (>2 minutes risks nerve/vascular issues)
- Not moving while wrapped (movement is essential)
- Wrapping over bony prominences without padding
- Using on acute injuries
Risks & Side Effects
Known risks:
- Nerve compression if too tight or left on too long
- Skin irritation or bruising
- Numbness/tingling (remove immediately if this occurs)
- Potential vascular issues with excessive duration
Contraindications:
- Deep vein thrombosis (DVT) or clotting disorders
- Acute injuries (fractures, severe sprains)
- Open wounds in treatment area
- Peripheral vascular disease
- Diabetes with neuropathy
- Skin conditions in treatment area
Safety rules:
- Never exceed 2 minutes wrapped
- Remove immediately if numbness, tingling, or color change
- Start with lower tension and progress
- Avoid wrapping directly over nerves (back of knee, inner elbow)
- Don't use if you have circulatory issues
Risk level: Low when done properly with time limits. Moderate risk if overused.
Who It's For
Ideal for:
- Athletes with joint mobility restrictions
- CrossFitters, Olympic lifters, gymnasts (overhead/squat mobility)
- Runners with ankle mobility issues
- Anyone with chronic joint stiffness
- Pre-workout mobility prep
- Post-training recovery for swollen joints
Especially helpful for:
- Limited ankle dorsiflexion (squat depth issues)
- Elbow restrictions (front rack position)
- Wrist mobility for front squats, handstands
- Post-sprain residual stiffness (once acute phase resolved)
Should avoid:
- Anyone with contraindications above
- Acute injuries (wait until inflammation subsides)
- Those uncomfortable with compression
- Hypermobile individuals (don't need more ROM)
How to Track Results
What to measure:
- Range of motion before/after (degrees or functional test)
- Perceived stiffness (1-10 scale)
- Functional movement quality (squat depth, overhead reach)
- Duration of effects
Simple tests:
- Ankle: Knee-to-wall test (measure distance)
- Knee: Deep squat depth
- Wrist: Wrist extension against wall
- Shoulder: Overhead reach to wall
Timeline:
- Immediate: ROM improvement (5-10+ degrees typical)
- 15-45 min: Effects duration
- Repeated use: May see cumulative improvements
Signs it's working:
- Immediate improvement in movement quality
- Reduced sensation of stiffness
- Better positions in training
- Less discomfort in end ranges

What voodoo flossing is and why it works for wrist pain
Chris Masterjohn explains the concept of voodoo flossing, crediting Kelly Starrett of MobilityWOD for popularizing it. He describes how wrapping an elastic band around a joint under compression while performing movement creates a synergistic healing effect when blood floods back in upon removal.
"If you know what voodoo flossing is, start doing it for your wrists. If you don't know what voodoo flossing is, listen on and watch the video in the show notes about how to do it for your wrists. But voodoo flossing is an idea that"
The compression and reperfusion mechanism behind voodoo flossing
Masterjohn explains the proposed mechanism of voodoo flossing -- performing movement under band compression partially restricts circulation, and upon removal blood floods into the joint at a greater rate to nourish and heal it.
"apparently there's some kind of synergistic effect between doing the movement under compression and then when you take the band off, getting this massive flow of blood flowing"
Step-by-step wrist voodoo flossing protocol
Masterjohn walks through a detailed wrist flossing protocol adapted from Kinetic Sports Rehab: open/close the hand, forearm rotation, wall extension with lateral movement, and floor reverse push-up position with forward, backward, side-to-side, and circular movements.
"Open and close your wrist back and forth maybe 10 times and then turn your arm clockwise and counterclockwise alternating and make sure you get that rotation all the way into the wrist maybe 10 times. Then you put your hand flat up against the wall and you try to get a 90 degree angle at your wrist."
Only 1-2 minutes per day for dramatic wrist pain relief
Masterjohn emphasizes the exceptional time efficiency of voodoo flossing for wrist pain -- only one to two minutes per day per wrist, with a remarkably high bang-for-buck ratio even for people without overt pain.
"you should try voodoo flossing to see whether it helps because it only takes one to two minutes per day per wrist to try it. And the impact in my experience is so great that there's, you know, few things that you could do for your wrists apart from not typing anymore that would have a"
Coach Boyle rediscovers voodoo flossing for knee pain
Host Anthony Randall introduces the voodoo flossing segment by noting Coach Boyle initially dismissed it but has become a big fan. Randall shares how he first tried it on his knee five or six years ago and found that despite the initial tightness feeling uncomfortable, movement under the wrap followed by removal produced immediate relief.
"Mike, speaking of something you didn't do when you were criticizing and now you're doing, a little bit of a little flossing here. But if you can see, this is ridiculous. I got this about five, six years ago, believe it or not, for my knee. Somebody, my buddy Ernie Lombardi had used it on me and I was like, wow, that feels pretty good. Like at first, because you're wrapping around that joint so tight, you're kind of like, oh, yeah."
Two minutes of knee flossing gives Boyle's wife next-day relief
Randall describes doing a two-minute voodoo flossing session on his wife's knee, and she reported it feeling better the next morning -- a rare endorsement since she typically dismisses his training suggestions. Boyle then shares how his physical therapist Bree Moscow started flossing his deteriorating right knee with the same positive results.
"No, this doesn't feel good. And then you do some exercise, you move around a little bit. And I do it for like two minutes. I did it with B last night. My wife, her knee was bothering her. And she actually was like, my knee feels better this morning. We do that again, which is very rare because everything I do, I'm an idiot. I'm the worst trainer in the world."
Using flossing on elbows and other joints with clients
Boyle describes expanding his use of voodoo flossing from personal knee rehab to client work, including wrapping a client's elbow with bursitis to try to pump fluid out. He notes the practical challenge of wrapping your own elbow compared to the knee, suggesting tape to anchor the band.
"When she wasn't around, I'd think, okay, I'll just wrap this thing up. I'll do a minute of kind of either leg press type action or leg extension type action, whatever it is, just something to get the joint moving and it would feel better."
