Theragun Prime Plus Review: 16mm Amplitude and Heat at a Rational Price

Design & Build Quality

The Prime Plus uses the same triangular ergonomic frame as the Pro Plus, which means three grip positions and practical self-treatment of the upper back without assistance. At 1.96 lbs it is slightly lighter than the Pro Plus and more comfortable for extended sessions. Four attachments (Dampener, Standard Ball, Thumb, Supersoft Ball) cover the essentials, though serious athletes may miss the Wedge and Cone included with the Pro Plus.

The integrated heat plate is the physical differentiator versus the standard Theragun Prime — it is a ceramic flat attachment that warms to three temperature settings and reaches treatment temperature in under 60 seconds. The build quality is the same premium Therabody standard: no flex under load, positive attachment engagement, textured grip.

Power & Performance

16mm amplitude at 40 lbs stall force. The amplitude matches the Pro Plus exactly — the same percussive depth into the muscle on each stroke. The stall force reduction (40 vs 60 lbs) means the motor begins to slow at higher applied body weight. For most personal recovery — applying the gun manually with hand pressure — 40 lbs is more than sufficient. For practitioners or athletes who brace the device against a table or floor and apply full bodyweight, the Pro Plus or Hypervolt 3 Pro’s higher stall force is the more appropriate choice.

Five speeds from 1,750 to 2,400 PPM. The heat plate operates independently of percussion speed.

Speed & Customisation

Five speeds, four attachments including the heated plate, and full Therabody app access. The heat attachment operates at three temperature settings (adjustable in the app) and can be combined with any percussion speed. The result is a genuine multi-therapy tool: heat first to increase local circulation, then percussion to address muscle tension.

App-guided routines are the same library as the Pro Plus — 150+ programmes across sports, conditions, and time of day. SmartScan body mapping works on the Prime Plus identically to the Pro Plus.

Noise Level

Comparable to the Pro Plus — approximately 55–60 dB at mid-to-high speeds. The triangular frame and QuietForce motor technology make it quieter than older-generation Theraguns. In practice: usable in a shared room at low speeds, audible across the room at maximum. Not suitable for use during a call or with sleeping partners nearby at full speed.

Battery Life

150-minute battery life at mixed speeds — identical to the Pro Plus. USB-C charging takes approximately 90 minutes. Internal battery, not removable. For daily 15-minute sessions, this covers 8–10 days between charges without daily topping up.

App & Software

Full Therabody app access — the same 150+ guided routines, SmartScan body mapping, and workout platform integrations as the Pro Plus. This is a meaningful advantage over the Theragun Prime, which has more limited app functionality. For users who engage with guided routines, the difference is substantive.

Data Privacy

Same as Theragun Pro Plus: US-based company, GDPR-compliant for European users, no data sales to third parties, data deletion available via account settings, fitness integration shares summary data only.

Value for Money

At $429, the Prime Plus sits between the Theragun Prime ($199) and the Pro Plus ($649). The heat therapy and app ecosystem are the two features that justify the price over the standard Prime. Against the Hypervolt 3 Pro at $349 — which provides higher stall force, a quieter motor, and six speeds — the Prime Plus’s $80 premium is justified only if 16mm amplitude or heat therapy are specifically required.

Final Verdict

The Theragun Prime Plus is the correct Therabody recommendation for most users who have decided they want Therabody’s 16mm amplitude. The $220 saving over the Pro Plus buys most of the same capability — with the exception of 20 lbs less stall force and two fewer attachments. For daily personal recovery, those are acceptable trade-offs.

Who Should Buy?

Buy the Theragun Prime Plus if:

• You want 16mm Therabody amplitude and heat therapy at a price below the Pro Plus
• You engage with app-guided routines and SmartScan body mapping

Buy the Theragun Pro Plus instead if:

• You need maximum stall force (60 lbs) and the full six-attachment set for professional or athletic use

Buy the Hypervolt 3 Pro instead if:

• Higher stall force (70 lbs) and quieter operation (51 dB) matter more than 16mm amplitude
