Lumphini Park

Evening aerobics in Lumphini Park, Bangkok, September 30, 2026 A big crowd steps and stretches across a wide paved road inside the park after dark, the towers of central Bangkok lit up behind them. This session was led by trainers from the Jetts gym chain, but the park's regular aerobics cost nothing: classes start around 6 p.m., with Bangkok Metropolitan Administration instructors leading one spot and volunteers taking a later 7 p.m. session. Bangkok's heat explains the timing, and the crowd explains the appeal: in a group this size, nobody is watching your footwork.
