Aerobic Step

Weirdly enough I don't actually use these for aerobics - I use them in weightlifting as a platform for doing deficit deadlifts.

They are very durable for aerobic steps - I have deadlifted with 160kg on the bar plus 80kg of bodyweight without any sign of weakness in the structure.

I have also seen them being used for box jumps (with the step against a wall) at Frank Yang (semi-famous YouTuber that has a very impressive 40" plus vertical jump) gym with lots of the pink height adding stacks - so they can definitely withstand large forces.

They are easy to adjust and add or subtract height with the pink stacks.
