Why Gen Z is swapping cardio for strength training

In recent years, there’s been a noticeable shift among younger generations, particularly Gen Z, from traditional cardio exercises like running and cycling to strength training activities such as weightlifting. This change reflects evolving fitness goals that go beyond just weight loss or toning up. Strength training offers numerous benefits including improved muscle mass, enhanced bone density, and overall functional health, which appeal to younger adults increasingly aware of long-term wellness.

Antonia Duffin, a personal trainer and gym owner in Manchester, highlights how her clients’ motivations have diversified. Some seek strength to support life events like pregnancy, while others aim to manage health conditions such as endometriosis through tailored workouts. Hybrid fitness trends like Hyrox, which combine different disciplines and add a social and competitive element, further illustrate how younger gym-goers are moving away from repetitive cardio routines in favor of more varied and engaging strength-focused sessions.

Data from Sport England supports this observation, showing that gym use and strength-related activities have risen slightly among adults aged 16 to 34 between 2016 and 2025. Meanwhile, participation in traditional cardio activities such as running, swimming, and interval training has seen a decline. Experts suggest this may be due in part to the rise of social media influencers promoting strength training and resistance workouts as effective and empowering ways to achieve fitness goals.

Moreover, the switch to strength training does not mean younger adults are less active overall; rather, their exercise routines tend to include more vigorous activity. Studies indicate that while older adults engage more in moderate exercise, younger people tend to undertake higher-intensity workouts, which can improve cardiovascular health, mental well-being, and physical resilience. This trend reflects a broader understanding that combining strength training with aerobic exercise produces comprehensive health benefits, motivating Gen Z to adopt more balanced and sustainable fitness habits
