Step aerobics is a form of group exercise that involves stepping on and off a raised platform, known as a step. This workout combines cardiovascular fitness with strength training, as participants perform various movements, such as lunges and jumps, while using the step. Classes are typically led by an instructor who guides participants through choreographed routines set to music. Step aerobics can be adjusted for different fitness levels by varying the height of the step or the intensity of the movements, making it accessible for beginners and challenging for advanced exercisers.
