The best places to use a massage gun on your back are the large, fleshy muscle groups on either side of the spine: the trapezius across the upper back and shoulders, the rhomboids between the shoulder blades, and the erector spinae muscles that run parallel to the spine from your mid-back down to your lower back. The key rule is to stay on muscle tissue and never press directly into bone, especially the vertebrae or the bony ridge of the spine itself.
Upper Back and Shoulder Area
The upper back holds some of the most common tension points in the body, and it’s one of the safest regions to target with a massage gun. The trapezius is a broad, diamond-shaped muscle that spans from the base of your skull down to the middle of your back and out to your shoulders. When you feel that familiar tightness between your neck and shoulders, that’s your upper traps. You can glide the massage gun slowly along this muscle, working from the top of the shoulder inward toward the spine (without touching the spine).
Beneath the traps sit the rhomboids, the muscles between your shoulder blades responsible for pulling your shoulders back. These get especially tight if you sit at a desk for long hours. To reach them, work the massage gun in the space between the inner edge of each shoulder blade and the spine. Stimulating these muscles improves circulation and can increase range of motion in both your upper back and neck, since tension here often contributes to neck stiffness.
The levator scapulae, a smaller muscle connecting the top of each shoulder blade to the upper neck, is another safe target. It sits along the side of the neck near the shoulder and is a frequent source of that “crick in the neck” feeling. Keeping the massage gun on the muscular part near the top of the shoulder blade, rather than moving up onto the neck itself, is the safest approach.
Mid-Back and Along the Spine
The erector spinae are a group of long muscles that run like two columns on either side of your spine from your pelvis up to the base of your skull. In the mid-back, these muscles are thick enough to absorb percussive therapy well. Move the massage gun slowly up and down each column, staying about an inch or more away from the bony bumps of the spine (the spinous processes you can feel if you run your finger down the center of your back).
If you find a spot that feels particularly tender or knotted, you can pause on it briefly. Physical therapists recommend keeping the massage gun on any single spot for no more than 20 seconds before moving on. Lingering too long in one area can irritate the tissue rather than relax it. A slow gliding motion, spending 1 to 2 minutes per muscle group, is more effective than hammering one knot repeatedly.
Lower Back: Proceed With Caution
The lower back is trickier. The muscles here (the lower portion of the erector spinae and the deeper multifidus muscles) are thinner, and they sit closer to the spine, kidneys, and other sensitive structures. You can use a massage gun on the lower back, but keep the pressure light, use a lower speed setting, and stay on the muscular tissue flanking the spine rather than pressing into the center.
If you have a known herniated or bulging disc, be especially careful. Improper technique or excessive pressure in the lumbar area can increase pain or aggravate the condition. For anyone with an active disc injury, sciatica, or spinal stenosis, it’s worth getting clearance from a provider before using percussive therapy on the lower back.
Where to Avoid
Three areas on or near the back are off-limits:
- The spine itself. Never run the massage gun directly over the vertebrae. The bony prominences have minimal soft tissue covering them, and percussive force on bone can cause bruising or irritation.
- The front and sides of the neck. Major blood vessels, including the vertebral and carotid arteries, run through these areas. A published case report in Clinical Practice and Cases in Emergency Medicine described a 27-year-old woman who developed a vertebral artery dissection (a tear in the artery wall that can lead to stroke) after repetitive use of a massage gun on the neck region. The anatomy here makes it vulnerable even to moderate percussive force.
- Directly on the shoulder blade bone. The flat surface of the scapula has very little muscle covering it. Work around the edges of the shoulder blade, not on top of it.
Which Attachment Head to Use
Most massage guns come with several heads, and three are particularly useful for back work:
- Flat head. The best all-around choice for the back. Its wide surface covers more territory with each pass, making it ideal for the broad muscles of the upper back and the area around the shoulder blades where tension spreads across wide zones.
- Fork head. Designed specifically for working along the spine. The two prongs straddle the vertebrae so you can treat the paraspinal muscles on both sides simultaneously without any force hitting the spine itself. If you’re going to use a massage gun on the erector spinae, this is the safest attachment.
- Ball head. Good for larger muscle groups like the glutes and lower traps. It distributes force more evenly than a pointed tip, which makes it comfortable on areas with moderate muscle mass.
Technique Tips for the Back
Reaching your own back with a massage gun can be awkward. For the upper traps and shoulders, you can hold the gun in one hand and reach across to the opposite side. For mid-back areas between the shoulder blades, angling the gun over your shoulder or reaching behind works for some people, but having someone else do it is more effective and lets you relax the muscles fully. Some massage guns come with extended handles for this reason.
Start on the lowest speed setting, especially if you’re new to percussive therapy. Let the weight of the gun do most of the work rather than pressing it hard into the muscle. Pushing too aggressively doesn’t make it more effective. It just increases the chance of bruising or soreness afterward. A light, steady pressure with slow sweeping motions across each muscle group for about 60 to 90 seconds per area is a solid starting point.
Pair massage gun use with regular movement. Tension in the upper back and shoulders often comes from weakness as much as tightness. Strengthening your back, arms, and shoulders through regular exercise helps the muscles better support your neck and spine, reducing the tension that sends you reaching for the massage gun in the first place.
