Expired Training Simulator Codes

Promo codes in Training Simulator do not last forever. Sun Day Studios rotates Strength and Crystal gifts when like milestones pass, when patches land, or when a gym-themed celebration ends. This page is the archive: strings that community lists once treated as active but that now fail for most accounts. Use it to stop wasting time, to learn the naming patterns, and to recognize fresh codes faster when they appear on the live Codes Hub.

Community trackers checked around 13 November 2026 moved several formerly hot codes into the expired bucket for Training Simulator (place 16572004551, universe 5703870642). Some trackers also cover sibling places—always confirm in-game. If Confirm still grants something on your account, enjoy it, then assume the window is closing.

Why codes expire

Training Simulator codes are marketing fuel, not permanent free income. Typical triggers:

1. Like-counter milestones — names often embed the number (520MUSCLES, 190KTRICEPS, older LIFT340K).
2. Patch days — see Updates and Changelog when the Roblox “Updated” stamp moves (last notable window around 2 April 2026).
3. Event swaps — limited pet-style codes (for example the Lava era) leave when the event UI leaves.
4. Silent rotations — a string stops working overnight with no group shout.

Expired does not mean “try harder.” Spamming Confirm on a dead code will not revive it and can make you miss the new list.

Recently rotated (mid-November 2026)

These were widely listed as active earlier and should now be treated as expired for most players:

Code	Former role	Notes
240KTRICEPS	Strength + Crystals package	Twin-style triceps drop; replaced by newer TRICEPS strings
LIFT340K	Strength + large Crystal payout	Excellent hatch bank while it lasted
FITNESS230	Strength + Crystals	Fitness-line predecessor to FITNESS500
410KTRICEPS	Strength + Crystals	Older triceps milestone

If you still have these saved in a notes app, delete them or move them here mentally so you only paste from the Codes Hub active table.

Older expired examples

Longer-tail community archives also include:

Code	Former reward style
20KTRICEPS	Strength + Crystals
300MUSCLES	Strength + Crystals
FITNESS160	Strength + Crystals
EFITNESS30 / fitness30	Strength + Crystals (case variants taught players to respect casing)
LAVARISE3	Limited pet-style reward (Lava Lord Pet era)

Case variants matter historically: players who typed fitness30 when the live string was EFITNESS30 (or the reverse) thought the code was dead when they only had the casing wrong. Always copy-paste from the wiki tables.

Naming patterns that predict new codes

Sun Day Studios and community like-parties reuse readable gym vocabulary:

• MUSCLES — often tied to like or visit style counters (420MUSCLES, 520MUSCLES, older 300MUSCLES).
• TRICEPS / KTRICEPS — Strength-heavy packages (190KTRICEPS, 510KTRICEPS, expired 240KTRICEPS, 410KTRICEPS).
• FITNESS — usually smaller dual Strength + Crystal grants (FITNESS500, expired FITNESS230, FITNESS160).
• LIFT — Crystal-forward strings while they last (expired LIFT340K).
• Event nouns — pet or map themes (LAVARISE3) that vanish with the event.

When the official place like count jumps or the Changelog notes a celebration, scan announcements for those roots before random Discord pastes.

How to use this archive responsibly

1. Redeem only the active table on Codes.
2. Learn the HUD once via How to Redeem Codes and Controls (Codes button on the right).
3. Keep this expired page as a do-not-paste list and a pattern teacher.
4. After a patch, assume yesterday’s “maybe still works” codes are gone until proven otherwise.
5. Spend successful Strength and Crystal grants on gear and eggs—see Training Gear, Pets, and Egg Hatching—instead of hoarding while waiting for a dead code to revive.

Active list snapshot (for contrast)

As of the November 2026 community check, the live hub highlights:

• 190KTRICEPS — 700 Strength + 300 Crystals
• 420MUSCLES — 500 Strength + 290 Crystals
• 520MUSCLES — 500 Strength + 290 Crystals
• FITNESS500 — 300 Strength + 140 Crystals
• 510KTRICEPS — 700 Strength + 300 Crystals

That set can change the same week you read this. The Codes Hub is always the source of truth for active; this page is the graveyard and the pattern book.

Spending leftovers after a rotation

When a Crystal-heavy code like LIFT340K dies, players often feel “behind.” You are not. Rotate into:

• Manual training on the best unlocked station (How to Train).
• Pet loadout hygiene (Pets Guide).
• Optional supported boosts such as Roblox Premium’s +10% Strength / +10% Speed or the historical Open 3 Eggs gamepass—covered in Premium & Boosts.
• Legitimate progression toward ranks and City World (Ranks, Rebirth & Worlds).

Avoid “private expired code revives” sold in DMs. Those scams steal accounts more often than they grant Strength.

Treat expired codes as history, not homework. Learn the MUSCLES / TRICEPS / FITNESS / LIFT vocabulary, redeem the five (or fewer) strings that still work, and put the Strength and Crystals into pets and stations before the next rotation lands.
