Using a Theragun comes down to a few simple principles: let the device do the work, match your speed and duration to your goal, and avoid bony areas. The technique itself is straightforward once you understand the basics, but small adjustments in how long you hold it on a muscle or which speed you choose can make the difference between an effective session and a wasted one.
The Basic Technique
The most important rule is to avoid pressing the Theragun into your body. Turn it on before placing it against your skin, then let the weight of the device provide the pressure. Pushing harder doesn’t mean deeper relief. It can actually bruise tissue and reduce the device’s effectiveness by restricting the head’s movement.
Start by gliding the device slowly across the muscle belly, the thick, fleshy center of the muscle rather than where it connects to bone or tendon. Move at roughly an inch per second, sweeping back and forth along the length of the muscle fibers. When you find a spot that feels particularly tight or tender, pause there for 15 to 30 seconds before moving on. You’re not trying to “break up” the knot through force. The rapid percussions stimulate blood flow and trigger small involuntary contractions that help the muscle release on its own.
A typical session on any single muscle group lasts between 30 seconds and 2 minutes. You can treat multiple areas in one session, but spending more than a couple of minutes on one spot offers diminishing returns and increases soreness risk.
Choosing the Right Speed for Your Goal
Theragun models operate between roughly 1,750 and 2,400 percussions per minute, and the speed you choose matters more than most people realize. A systematic review in sports physical therapy research found clear differences in outcomes depending on frequency and duration.
For flexibility and range of motion: Use a higher speed (above 40 Hz) for 2 minutes or less per muscle group. Short, intense bursts help loosen tissue without reducing your ability to generate force afterward. This makes it a good option before stretching or mobility work.
For post-workout recovery: Use a lower speed (below 40 Hz) for longer than 2 minutes per muscle group. Slower, sustained percussion reduces muscle stiffness and the soreness that builds in the 24 to 72 hours after hard training.
Before strength or explosive exercise: Be careful with timing. Research shows that using a massage gun within 5 minutes of a strength or power activity can actually harm performance. If you want to use your Theragun before lifting or sprinting, do so at least 5 to 10 minutes beforehand, and keep the session brief.
Which Attachment to Use
Most Theraguns come with several interchangeable heads, each shaped for a different purpose. You don’t need to overthink this, but using the right one makes a noticeable difference in comfort.
- Standard ball: The most versatile option. Works well on large muscle groups like quads, hamstrings, glutes, and upper back.
- Cone (or bullet): A pointed tip designed for trigger points and deep tissue work. Use it on specific knots or along the muscles beside your spine (not on the spine itself).
- Wedge: Shaped like a flat blade, useful for scraping along muscle fibers in areas like the IT band, hip flexors, or shoulder blades.
- Supersoft (dampener): Cushions the percussive force for tender or bony areas near elbows, knees, and joints. It still increases blood flow and oxygen delivery while being gentler on sensitive spots.
- Thumb: Mimics the pressure of a therapist’s thumb for targeted work on the lower back or feet.
If you’re new to percussive therapy or have particularly sore muscles, start with the standard ball or supersoft attachment before graduating to more focused heads.
How It Works in Your Body
When the Theragun strikes your muscle at high speed, it creates shear stress on the tissue that triggers the release of compounds causing blood vessels to dilate. A study on healthy participants found that skin temperature in the treated area rose by nearly 4°C and muscle oxygen levels increased by about 6% after a single session, peaking around five minutes post-treatment. Blood flow spiked immediately and remained elevated.
The rapid vibrations also activate muscle spindles, sensory receptors embedded in the muscle that detect stretch. This triggers tiny involuntary contractions and relaxations that increase the muscle’s demand for oxygen and further boost circulation. The combined effect is more blood flow, more oxygen delivery, and faster clearance of the metabolic byproducts that contribute to soreness and stiffness.
Where to Avoid Using It
Percussive therapy is safe for most people on most muscle groups, but certain areas and conditions call for caution.
Never use a Theragun on:
- Bony prominences: The spine, shin bone, collarbone, and any area where bone sits close to the skin surface. The percussive force can cause bruising or pain against hard tissue.
- The front and sides of the neck: Major blood vessels and nerves run close to the surface here. Stick to the muscles at the back of the neck and upper traps.
- Open wounds, recent surgical sites, or areas of acute inflammation: Increased blood flow to these areas can worsen swelling or delay healing.
People with blood clots or a current deep vein thrombosis should avoid percussive massage entirely, as the force could dislodge a clot. A past history of clots doesn’t necessarily rule it out, but talk to your doctor first. Those with severe osteoporosis should also avoid strong percussive pressure, particularly around the spine, as weakened bones can fracture under repeated force.
A Routine for Common Muscle Groups
Here’s a practical approach you can follow after a workout or at the end of a long day. Use a low to medium speed and spend about 90 seconds on each area.
Quads: Start just above the knee and sweep slowly up toward the hip. Cover the front and outer thigh in long, overlapping passes.
Hamstrings: Sit on a chair or the floor and run the device from just above the back of the knee up to the base of the glute. If you find a tight spot, hover there for 15 to 20 seconds.
Glutes: Work in slow circles across the entire muscle. This is one area where you can comfortably spend closer to 2 minutes, since the tissue is thick.
Upper back and traps: Use the device on the muscles flanking your spine, never on the vertebrae themselves. Sweep from the base of the skull down to the mid-back, then across the top of the shoulders.
Calves: Start at the Achilles tendon and work up to the back of the knee. The cone attachment works well for getting into the deeper calf muscle.
Feet: Use the standard ball or thumb attachment on the arch and heel. Keep the speed low. Even 30 to 60 seconds per foot can relieve tension from standing or running.
Using the Therabody App
If your Theragun model connects to the Therabody app, it’s worth using at least once to calibrate your technique. The app provides real-time feedback on how much force you’re applying and lets you control speed between 1,750 and 2,400 percussions per minute from your phone screen. It also offers guided routines for specific goals, including a six-minute sleep protocol designed to be used in the 30 minutes before bed. Vibration and sustained pressure have a calming effect on the nervous system, and the routine targets areas like the neck, upper back, and feet at low speeds to help shift your body toward a more relaxed state.
The app is designed for one-thumb navigation so you can control it while holding the device with your other hand. It’s not essential for getting results, but the force meter is genuinely useful for training yourself to stop pressing too hard.
