The new Gen5 Pro does keep a bit of the heft, but feels lighter in the hand when compared to the Gen4. Mechanical stimulation of a muscle [with a device like the Theragun] causes increased blood flow and the release of histamines to the stimulated area. For one, the new OLED screen at the top of the handle provides a more detailed overview of settings and routines.

The Relax is larger, with two additional attachments and a wider range of intensity levels, but I prefer that the Move is so compact. Both featuring the triangle ergonomic handle and an adjustable arm, you can hardly tell the two models apart. Previously, you needed the app for guidance on which handle part to hold and which parts of the body you’re supposed to use the Theragun Pro on during a routine. Both attachments were great at their specific fields, with the fork easily targeting the spinal area, while the wedge made any lower body aches fade away routinely. The triangle-shaped silhouette of the Theragun Pro, however, did make it easier to hit far-off knots like at the back of the hamstring.

While I won't say it's non-existent — you still hear a slight purr of the motor during use — the decibels have dropped significantly, especially when compared to the previous generation.

The QX150 Professional motor inside the fourth generation Theragun PRO and the EQ150 Professional motor inside the fifth generation Theragun PRO both only reach their limits at 60 lbs of resistance.Thankfully, though, the brand's updates to the all-new EQ-150 motor have definitely quieted each recovery session. Due to the lack of a handy carrying case, though, we think this is a great option for at-home use, whereas the Theragun is a little more travel ready. While the carrying case does pack nicely in a gym bag due to its more compressible corners, there was a heightened sense of durability with the older hard case. With all this testing, however, I did begin to harken back to the older Gen4 model; it's still a damn fine device in its own right.
