Power through cardio circuits, squats, and step-up routines on a 28-inch aerobic step platform with three height settings at 4, 6, and 8 inches. High-density Pp base resists bending and cracking under repeated high-impact use, while the textured non-slip surface and rubber feet keep you stable and protect floors. Four stackable risers store neatly under the deck for compact organization. Versatile enough for home fitness, rehabilitation exercises, and everyday household step-assist tasks.
