Coach Abbey @ajoy10 brings the burn — and the reviews prove it. 🔥💿

Legs shakin’. Booty burnin’. Sweat dripping.
Basically, the full Underground lower-body experience in one 5-star review.

Abbey is phenomenal. Per usual.
She knows how to push the room, keep the energy high, and make every rep feel worth it — even when your legs are questioning all of your life choices.

Come catch class with Abbey and feel the burn for yourself. 🖤⚡

🎵 Rolling Stone Rewind: Kurt Cobain + NIRVANA

One album. One swimming baby. One seismic shift in music.

On September 24, 1991, Nirvana released Nevermind—the album that took the band from the Seattle scene to worldwide fame and helped send alternative rock and grunge crashing into the mainstream.

“Smells Like Teen Spirit” became an anthem, but Nevermind also gave us “Come as You Are,” “Lithium,” and “In Bloom.”

Fun fact: Nevermind eventually knocked Michael Jackson’s Dangerous out of the No. 1 spot on the Billboard 200—a pretty incredible snapshot of just how dramatically popular music was changing in the early ’90s.

Our June 2002 Rolling Stone issue featuring Kurt Cobain takes us right back to an artist and an era that completely changed the sound of a generation.

From underground to everywhere.

Come as you are. The classics never left. 🎸

👉 Swipe to see how many Nirvana albums our team can find hiding on our massive CD wall. 💿

CD Wall Spotlight: Empire Records: The Soundtrack 💿 

“Damn the man. Save the Empire.”

We’re taking this CD Wall Spotlight straight back to 1995 and one of the most beloved cult movies of the decade: Empire Records.

A movie about a bunch of young record-store employees obviously needed a killer soundtrack — and this one delivered. Gin Blossoms, The Cranberries, Edwyn Collins, Toad the Wet Sprocket, Better Than Ezra and more turned this soundtrack into a perfect little time capsule of ’90s alternative music. 

And this time, finding the CD wasn’t the only assignment. 😂

Coach Abbey @ajoy10 took a minute to give us her best Gina, recreating Renée Zellweger’s pose from the soundtrack cover. Swipe through to see how she did. 👀

Bonus fun fact: Renée actually contributed vocals to the movie version of “Sugarhigh.” 

Thirty-one years later, we’re still wishing Empire Records were a real place we could hang out.

Damn the man. Save the music. 🎶

🎸 ROLLING STONE REWIND 🎸

Loud guitars. Big hair. Even bigger attitude. This week we’re throwing it back to Guns N’ Roses. 🌹

On September 17, 1991, Guns N’ Roses released Use Your Illusion I and Use Your Illusion II on the same day — two massive albums that defined an era.

Between the two records we got “Don’t Cry,” “You Could Be Mine,” “Civil War,” and the epic “November Rain.” 🤘

⭐ Fun fact: The albums debuted at No. 1 and No. 2 on the Billboard 200 — with Use Your Illusion II landing at No. 1 and Use Your Illusion I at No. 2. Not a bad week for GNR. 

Our Rolling Stone issue featuring Guns N’ Roses takes us right back to this iconic era — a band that wasn’t just making music, they were a full-on cultural phenomenon.

And apparently, we have a LOT of GNR hiding around The Underground. From the Appetite for Destruction poster on our ride room door to the CDs lining our walls, the nostalgia is everywhere.

👉 Swipe to see our coaches and crew finding all the GNR nostalgia around the studio — and catching up on the latest headlines from 1991 while they’re at it. 😂

Appetite for nostalgia. Always.

Want to see this iconic Rolling Stone issue in person? Next time you’re in the studio, stop by our Rolling Stone wall and check it out.
