The Gym Gains event gives you rewards for submitting brainrots of different weights to the Planet Freshness gym on Central Island. You need to submit 25 brainrots total to unlock all the rewards. In this guide, I will show you how to complete the Gym Gains event in Plants vs Brainrots.

What is the Gym Gains Event in Plants vs Brainrots?
The Gym Gains event works like a real gym workout. You submit brainrots to the NPC at the Planet Freshness studio, and they bench press each one. Every time you submit a brainrot, the weight requirement goes up, just like adding more weight to your lifts as you get stronger.
You can find the event on Central Island, right behind the Fireworkino. The event replaced the New Year countdown event and will give you steady rewards for each brainrot you submit.
