It sounds like they're talking about pistol whip.

If I can promote one myself, Synth Riders can be a hell of a workout. People like comparing it to beat saber. Unlike beat saber, there's no swords, so there's a lot less wrist movement and a lot more arm/full-body movement. It feels a lot like dancing while you're doing it. I'm no great fan of exercise, but if I'm not careful I can exercise myself deep past exhaustion in this one -- especially on the harder difficulty charts.

And beyond that there's a mode where you punch the notes instead of trying to catch them. I haven't tried it, but that sounds even more demanding.

But aside from anything else, it's just fun! Great option for training cardio, it really works out the arms.
