Which controller do you use for Anki? Also, I assume the combo with LISS needs to be done on a treadmill? I heard of somebody who used an audio plugin, but my cards are not so audio-friendly.
I actually do them on an exercise bike at home. For the time being I just use an Xbox controller, which I hold while pedaling. LISS cardio is pretty easy to stay in the groove of, so I don't need to actively hold onto the handles to stabilize myself.
