Bowflex

Bowflex is a minor meme on the SiIvaGunner channel. It is based on the commercials for the Bowflex brand of training machines.

Rips
Rips including the Bowflex meme invoke the "bait-and-switch" joke of SiIvaGunner by starting with the original song and unexpectedly dubbing the music over a Bowflex advertisement.

Later rips of Bowflex (such as "Sahasrara - Shin Megami Tensei: Digital Devil Saga", "Start OF THE END - Yakuza: Dead Souls", and "Life Will Change - Persona 5") would comically dub Bowflex advertisements. "Virtical Point - Yakuza Kiwami" features an actual real-life parody of Bowflex advertisements.

This also might be of how the rips that sound like rock music have the Bowflex meme, seeing how actual Bowflex commercials use rock as background music.
