Did you know your favorite HIIT class owes a lot to 1980s step aerobics? Back then, it was all about high-energy moves on a simple platform, blasting synth tunes, and sweating it out with friends. While HIIT today uses more gear and mixes up the intensity, the group vibes, music, and full-body burn all started with step. Next time you’re crushing intervals, thank those neon leg warmers for the inspo! #HIIT #StepAerobics #FitnessHistory #WorkoutTrends #GroupFitness #Health
