Artist's commentary
Hang in There, Kogasa-san #3816
Anaerobic exercise uses sugar as an energy source, while aerobic excerise uses fat; that's another difference. Ring Fit still builds muscle and ups basal metabolism, though, so it's not like it's a waste of time.
Also, I get to enjoy BL scenes between Ring and Dragaux. :-)
