Treadmills to deadlifts: Why Gen Z are swapping cardio for strength training

How Social Media Shapes Workout Preferences

Antonia Duffin, 34, began her fitness journey aiming to lose weight and tone up, but her routine evolved into a central part of her daily life. What started as a personal goal transformed into a consistent gym habit, reflecting a broader shift in how younger generations approach exercise. This change is evident in gyms across the country, where traditional cardio machines are seeing less use as strength training gains popularity.

The rise in strength training among Gen Z and younger millennials reflects a deeper understanding of fitness beyond weight loss. Many now prioritize building muscle, improving functional strength, and enhancing long-term health over burning calories on treadmills or ellipticals. Social media has played a role in showcasing the benefits of lifting weights, with influencers and athletes demonstrating routines that focus on compound movements like squats, deadlifts, and bench presses. Gyms have responded by expanding free weight areas and offering more strength-focused classes.

What Are the Long-Term Benefits of This Shift?

Platforms like Instagram and TikTok have normalized strength training, especially for women, by breaking down stereotypes that lifting weights leads to bulkiness. Instead, content highlights improved posture, increased confidence, and better mental health. Antonia noted that seeing others share their progress online helped her stay motivated and feel part of a community. Data from fitness apps shows a 40% increase in strength training logs among users under 30 over the past two years, while steady-state cardio sessions have declined by nearly 25% in the same group.

Experts say the move toward strength training offers lasting advantages, including improved bone density, better metabolic health, and reduced injury risk as people age. Unlike cardio, which primarily benefits cardiovascular endurance, strength training supports joint stability and muscle retention—key factors in maintaining mobility later in life. Antonia said she now feels stronger in everyday tasks, from carrying groceries to playing with her niece, and views fitness as a lifelong investment rather than a short-term fix.

Is strength training only for young people? No, strength training benefits individuals of all ages. Older adults can safely build muscle with proper guidance, improving balance and reducing fall risk.

Frequently Asked Questions

Do I need to lift heavy weights to see results? Not necessarily. Progress comes from consistent effort and gradually increasing resistance, whether through bodyweight exercises, resistance bands, or lighter weights with higher reps.

Can I still do cardio if I focus on strength training? Yes, many people combine both. Short cardio sessions or activities like walking and cycling can complement strength work without interfering with muscle growth.
