Fitness trends for 2025 are shifting towards wellness and sustainability, with less emphasis on aesthetics and more focus on how people feel. Longevity fitness programmes for older adults have emerged as the number one trend, while Pilates continues to grow in popularity, particularly among women, offering a combination of strength and mobility without joint impact. Strength training remains a baseline activity, but the motivation is changing towards future-proofing the body for long-term health rather than appearance.
