If you thought that Season 1 of Physical: 100 was larger-than-life, Season 2 is going to be an even bigger flex.

That’s right — the Korean reality competition series is back on March 19 and pushing the limits again. In Physical: 100 Season 2 — Underground, the stakes are even higher, the challenges are even harder, and the arena — a massive mine — is even more extensive. But much will still be familiar: Like before, a group of 100 diverse contestants of all ages, gender identities, and fitness backgrounds will compete in various quests to determine who has the “ideal physique.” And as we’ve learned, the answer isn’t as obvious as you’d think.
