Outdoor Fitness Brisbane: Exercise Cuts Anxiety 50%

A 45-minute jog along the Kangaroo Point cliffs or a sweaty session in New Farm Park’s bootcamp zone might be as effective as a low-dose antidepressant for mild to moderate anxiety, according to a meta-analysis published this month in the British Journal of Sports Medicine. The review, which pooled data from 35 randomised controlled trials involving 3,082 participants, found that exercise programs lasting at least 12 weeks produced a clinically significant reduction in anxiety symptoms-comparable to the effect sizes seen with first-line medications like SSRIs.

The timing of these findings is no small thing in Brisbane. The city's notoriously humid summer peak has pushed more residents indoors, and the mental health helpline 1300 MH CALL reports a 14 per cent spike in anxiety-related calls during January and February compared to the same months in 2025. Lifeline Queensland confirmed to The Daily Brisbane that its 13 11 14 line experienced its highest-ever call volumes in March this year, with many callers citing ongoing cost-of-living pressures. The intersection of financial stress and rising temperatures creates a perfect storm for heightened anxiety, researchers say.

Where Brisbane Is Feeling the Burn

South Bank’s exercise precinct, with its free outdoor gym equipment, Saturday morning yoga sessions on the River Quay Green, and the 870-metre Arbour Walk that doubles as a jogging track, saw a 22 per cent increase in user traffic in the first six months of 2026 compared to the same period last year, per Brisbane City Council sensor data. The council spent $4.7 million in the 2025-26 budget to upgrade the parklands’ exercise nodes, adding eight new resistance stations and resurfacing the running circuit along the riverbank.

At New Farm Park, the Saturday 7 a.m. bootcamp run by The Body Project, a local fitness studio operating since 2019, now caps attendance at 40 after numbers swelled past 60 in May. Owner Simone Tran told members in a group email last month that the waitlist had hit 60 names. On weekday afternoons, the park’s open-air calisthenics area-complete with pull-up bars, parallel bars, and a dedicated stretching platform-is often fully booked from 4 p.m. to 7 p.m., according to council booking records obtained by The Daily Brisbane.

The Gears That Make It Work

The physiological mechanism is gaining mainstream attention. When you elevate your heart rate to 70-85 per cent of its maximum-a zone easily reached on the steep climb from the city botanic gardens up to the Goodwill Bridge approach-the body releases endorphins and reduces levels of the stress hormone cortisol. A separate study published in Frontiers in Psychiatry in March 2026 found that participants who performed three 50-minute moderate-to-vigorous sessions per week for eight weeks had 31 per cent lower resting heart rates and reported 38 per cent fewer symptoms on the Generalized Anxiety Disorder 7-item scale, compared to a control group that maintained standard daily activity.

That matters here: Brisbane has the highest proportion of outdoor gym users among Australian capital cities, with 58 per cent of adults reporting they exercised in a public park or riverwalk at least once a week, according to the Queensland Household Survey 2025 (the most recent data available). The same survey found that 43 per cent of respondents said they exercised outdoors specifically to improve their mood, not just to maintain physical fitness.

For those looking to start, fitness physiologist Dr. Emma Langton (Griffith University’s School of Health Sciences and Social Work, not available for interview) has publicly recommended the “20-10-10” rule: 20 minutes at a conversational pace, 10 minutes at a “huff-and-puff” pace, and 10 minutes of stretching or slow walking. Griffith University runs a free community exercise program called Move for Mind at the Nathan campus every Tuesday and Thursday at 6 a.m., enrolling participants for eight-week blocks. The program’s website lists the next intake opening on 1 August 2026.

The research is clear: exercise won't replace therapy or medication for everyone. But for many Brisbane residents, the free, accessible prescription is just a short walk or bus ride away. The hardest part might be lacing up your sneakers and stepping onto the river path.
