Fernanda Silva stands in a converted garage in Complexo da Maré at 5:45 a.m., rolling out yoga mats for the day's first class. The space has no air conditioning. The walls need paint. But on this July morning, twelve people have shown up—construction workers, domestic cleaners, a retired bus driver—each paying 25 reais to spend an hour in poses that their bodies have never tried before.
The timing matters. Across Rio de Janeiro, brutal heat is reshaping how the city's poorest residents think about their bodies. Temperatures have reached 37 degrees Celsius on several days this month. The affluent retreat to climate-controlled gyms in Barra da Tijuca and Ipanema. The rest of Rio adapts, shifts schedules, and increasingly seeks out spaces like Silva's studio where community, not luxury, is the selling point.
The grassroots infrastructure boom
In Santa Teresa, a neighborhood of narrow colonial streets and crumbling mansions, Marcus Oliveira runs Corpo e Mente from a repurposed colonial townhouse on Rua Almirante Alexandrino. The operation is bare-bones: mismatched dumbbells, resistance bands looped over nails, a sound system that cuts out during power dips. But his classes for seniors—thirty-seven people attended last Tuesday—cost 40 reais per session. Most participants are over 60. Many have hypertension or early-stage diabetes. Oliveira, a personal trainer for twenty-two years, gets no government funding. He makes it work through volume and reputation.
The city's municipal health department estimates that roughly 62 percent of Rio residents are overweight or obese, according to 2025 data. But formal gym memberships remain beyond reach for most. A basic annual membership at a major chain runs 800 to 1,200 reais. Silva's informal classes, at 100 reais per month with no contract, serve people for whom that difference is not small.
Down in Botafogo, a different model is emerging. Sabor de Casa, a cooperative that launched two years ago, combines food education with community meals. Fifteen women—all from low-income households—rotate through a commercial kitchen on Rua General Severo, learning to cook nutrient-dense meals from whole ingredients while selling affordable plates to neighborhood residents. A lunch of black beans, grilled chicken, and collard greens costs 18 reais. The program also teaches basic nutrition literacy in Portuguese and covers the rising cost of fresh produce in peripheral neighborhoods.
Why this moment matters
The heat spike has coincided with a broader reckoning about health inequality in Rio. The city's public health system is stretched thin. Preventive care remains a luxury. For decades, wellness was something that happened in air-conditioned private spaces in Zona Sul. Now, as temperatures make that inaccessible and as people's economic situations grow tighter, the definition of wellness has started to shift toward something more practical and communal.
Real numbers back this up. Visits to public health clinics in North Zone neighborhoods like Complexo da Maré jumped 23 percent in June compared to June 2025, according to municipal health office figures released this week. Many visits are heat-related, but staff report increasing numbers of people seeking preventive care—blood pressure checks, diabetes screening, basic fitness guidance—for the first time.
For people starting these grassroots programs, the equation is straightforward. Your body does not wait for government funding or perfect conditions. Silva teaches yoga in that unair-conditioned garage because people in Maré need to move, need community, need affordable options. Oliveira keeps his studio open in Santa Teresa because his students have nowhere else to go. The women at Sabor de Casa cook because their families need food.
If you're looking to join these spaces—and many Cariocas are—start by asking neighbors and local shop owners. Word of mouth remains the primary recruitment tool. Classes fill through Instagram accounts and WhatsApp groups, not slick marketing. That informality is part of what makes these places work. No corporate overhead. No pressure to upsell. Just people trying to stay well in a city that does not always make it easy.
