How should the tier list be updated?

Use checked rankings, explain use cases, and split beginner, rank-push, trading, and update-watch picks when the evidence is still early.

Checked July 14, 2026

Gym Star Simulator Tier List

Compare the safest code reward, trainer watch picks, pet value candidates, and Muscle Factory update items before spending spins, boosts, or trade value. The July 14 pass still did not surface a fresh creator-owned trainer or pet ranking sheet.

Ranking criteria

Rank speed, boost value, trade risk, and update freshness

Compare picks by rank-push value, trainer impact, pet value, unlock cost, source strength, and replacement risk.

Source notes

Confidence labels: official, reported, older, and needs-check

Treat official Roblox text as strongest. The July 14 pass verified the Discord invite and update wording, but no creator-owned trainer or pet ranking sheet surfaced.

Best current picks and watchlist

Use the S and A entries first, then treat Watch entries as update leads until current trainer stats and pet values are confirmed.

The official Roblox page now lists WORLDCUP for enchantment crystals and wheel spins, so it is the safest first action before comparing trainers or pets.

Player note: Use the spins and crystals before a planned rank push so the rewards can affect your next training session.

Use source-backed codes first, then decide whether spins and boosts support a rank push.

Rank pets by trade demand, event freshness, and whether current values are still reliable.
