Hailey Bieber recently revealed a shift in her fitness priorities, moving away from Pilates toward strength training. In a recent interview, the model stated that Pilates is "a little over," signaling a change in her workout philosophy.

This pivot reflects a broader fitness trend. Many athletes and trainers now emphasize strength training for functional fitness and long-term metabolic health. Building muscle through resistance work offers benefits Pilates alone cannot deliver. Strength training increases bone density, boosts metabolism, and improves functional movement patterns—all critical for aging well.

Bieber's trainer recommends a focused glute-activation routine featuring three core movements. The glutes represent one of the body's largest muscle groups. Strengthening them improves posture, reduces lower back pain, and enhances athletic performance. Unlike Pilates, which emphasizes controlled movements and core stability through body-weight resistance, strength training uses progressive overload to build muscle tissue systematically.

The science supports this approach. Research from the American College of Sports Medicine shows that resistance training twice weekly produces measurable gains in muscle mass and strength. A 2022 study published in the Journal of Applied Physiology found that progressive strength work significantly improved metabolic function in adults of all ages.

That said, Pilates remains valuable for mobility and mind-body connection. The two approaches work best together. Many fitness professionals now recommend combining strength training's muscle-building benefits with Pilates' flexibility and control work.

For those considering a similar shift, start with foundational movements. Squats, deadlifts, and hip thrusts target the glutes effectively. Consistency matters more than intensity. Three sessions weekly, with adequate recovery, produces sustainable results.

Bieber's willingness to reassess her fitness routine reflects maturity in health pursuits. Bodies change. Training needs evolve. What worked at
