Why Amplitude and Stall Force Matter When Choosing a Massage Gun

With so many percussion massage guns on the market, it is easy to assume they all do the same thing. However, most cheap options are just vibrating gadgets that buzz on the surface of your skin rather than treating tight muscles. If you want real muscle relief and faster recovery, you need to look at two critical specifications: amplitude and stall force. This is exactly where Theragun sets itself apart from the competition.

​

The Breakdown: Amplitude and Stall Force

​

These two factors determine whether a massage gun can actually break up stubborn knots or if it will just choke when you apply pressure:

• Amplitude (The Depth): Amplitude is how far the massage gun head extends and retracts. Most generic massage guns have a shallow amplitude of 10mm or less, which just vibrates the surface of the skin. Theragun features an industry-leading 16mm amplitude, allowing it to punch 60% deeper into the muscle tissue to target deep soreness and release tight fascia.

• Stall Force (The Power): Stall force is the amount of pressure you can apply to the device before the motor completely stops. Cheap massage guns have very low stall force, meaning the moment you press down into a tight glute, hamstring, or shoulder, the motor dies. Theragun’s high-torque commercial-grade motor is built to handle heavy pressure without stalling, allowing you to get deep into the muscle where you need it most.

​

The Bottom Line

​

A massage gun is only effective if it can reach the muscle and handle the pressure required to release it. While knock-off brands compromise on both depth and power to lower costs, Theragun stands above the competition by delivering true, deep-tissue therapy that won't quit under pressure.
