Overview

A 16 x 16 inch aerobic step platform with a rubber non-slip top, rated for users up to 300 lbs. Risers let you adjust the height between 4 and 6 inches on the 2-riser version or 4 and 10 inches on the 4-riser version.

Marcy's Circuit Fitness step targets the classic aerobic-step and home-gym-PT use case rather than higher-load platform training. Only the bottom riser layer has a full solid base; the layers above it are open, which one buyer flagged as their only complaint. The compact footprint is built for smaller rooms rather than large studio spaces.

  • 16 x 16 inch platform, 300 lb weight rating
  • Height adjusts 4-6 inches (2 risers) or 4-10 inches (4 risers)
  • Rubber non-slip top surface
  • Non-skid rubber feet for stability

Who it's for

Good for home gym users doing step-up, glute bridge or mountain climber work in a small room, and it also shows up in reviews as a physical therapy tool for knee rehab. Anyone wanting a fully solid platform at every riser height should note the open construction above the base layer.

What buyers say

From Amazon customer reviews.

Buyers repeatedly call it sturdy and stable for step-ups and PT exercises, including knee rehab where the adjustable height helped track progress. The most common complaints are a grip surface that can peel at the corners after weeks of use and the open construction under the upper riser layers.
