Game Overview

Mobile Trainer (Japan) is one of those weird little Game Boy Color games that makes you go, "Wait, this actually exists?" It's basically a pocket-sized workout coach from 1999—way before fitness games were cool. You’ll be punching the air to hit targets, doing silly little stretches, and trying to keep up with the chiptune bleeps telling you when to move.

It’s not exactly a gym replacement (your arms might get tired, though), but there’s something oddly charming about how seriously it takes its pixelated aerobics. The whole thing feels like someone took a Jane Fonda VHS and ran it through an 8-bit filter. If you’ve ever wanted to sweat while staring at a tiny green screen, this is your chance.

Good luck finding a copy, though—it’s one of those Japan-only oddities that pops up occasionally and makes collectors raise an eyebrow. Worth it just to say you’ve played a Game Boy game that makes you stand up.
