Hailey Bieber is basically the face of Pilates—she’s got the strong core, great posture, toned arms and glutes, and that laser focus. (Makes sense, she runs Rhode.) But back in spring, she admitted she thought it was getting a bit overhyped. “I love Pilates, I really do,” she told TIME. “But I think it’s become a bit of a trend, and it’s really hard to find good teachers who actually care about form.” Even though she’s been focusing more on strength training and trying out weighted vests, she still knows nothing beats that burn you get in a Pilates class.

Yesterday, Hailey and her husband Justin Bieber were spotted leaving Forma Pilates in Los Angeles after a session, each holding an iced coffee. That studio—which is referral-only and has locations on both coasts—has long been a favorite for celebs like the Hadids, Lori Harvey, and Kendall Jenner. Hailey’s been a loyal regular for years, often seen leaving in matching Alo or CSB workout sets. This time, she went with an all-black look: a body-hugging tank, straight-leg yoga pants, and a cream cardigan tied neatly around her waist. Justin matched the vibe in an oversized graphic tee, basketball shorts, and SKYLRK boots. (The Biebers are a perfect example of how activewear is shifting—people are moving away from the uniform look and embracing color and personal style when they work out.)

Whether Justin actually did a 45-minute session on the reformer or just waited for Hailey with their iced drinks, being a “Pilates princess” isn’t limited by gender—anyone can benefit. Basketball players, soccer stars, and Olympic athletes of all genders have made low-impact workouts like Pilates, barre, and yoga key parts of their training. Glen Powell, Harry Styles, David Beckham—they’re all into it. (And it’s not the first time Justin’s been spotted at the studio either.) There was a phase on social media where overly confident gym guys got humbled on the reformer, legs shaking as they tried to do a lunge with tiny 2-pound weights—but we’re way past using Pilates as a joke for men now.

Pilates was originally created by Joseph Pilates, who was a gymnast and boxer. For men specifically, it can be a total game-changer. If you’re only doing strength training or running, you’re missing out on working your deep core muscles—like the diaphragm, obliques, and pelvic floor. After the pandemic, a national Pilates chain reported a 71 percent year-over-year increase in male memberships, according to GQ.

If you commit, you’ll see impressive results pretty fast. As Laura Quinn, head Pilates trainer at Alo Wellness Club in LA, puts it: “The rise and popularity of reformer Pilates has come from people seeing their personal results quickly.”

The workout focuses on core strength, flexibility, and alignment, with an emphasis on core activation: strengthening those muscles improves posture, helps prevent injuries, and gives your whole body a stable foundation. With the spring resistance of the reformer and moves that use your own body weight, your muscles get challenged in controlled, flowing movements. You’ll fix muscle imbalances, improve posture and flexibility, and more. Plus, the reformer lets you target areas you might not think about in a regular strength workout.

Pilates really does it all: it’s low-impact, high-result, and works for beginners and pros alike. Building that mind-muscle connection—no matter your gender or activity—is key to getting more out of your workouts. So take a page from Hailey Bieber and grab your Justin for a reformer session.
