I bought this step because i needed one in a hurry and it was the cheepest one. Well I should have waited to buy a more expensive one. This one is not big enought for me to workout on comftrable. I cant get my whole foot on the step which is what always needs to happen and it also is not long enough to do some of the moves so i was not able to really push myseld when i needed to for fear of falling off. But at least my daughter can pick up areobics because it is the perfict size for her now only if they would allow 5 years olds in the class to join.
