To begin with, are you a beginner exerciser or more advanced? Let me say that I personally have not used the Easytone step, but use the regualr Reebok step for many different exercises when teaching my classes (and absolutely love the durability and versatility of it). Both steps may give you a good workout, but here are my concerns with the easy tone step vs. the regular Reebok:
–If you are a beginner on the Easytone and working on core strength, your form may be compromised with the balance aspect. Larger muscle groups may take over the core muscles.
–You may be limited with strength on the Easytone vs. the regular step. The balance challenge may limit the amount of weight you can use if that’s an option for you. (An example would be you using dumbbells for lunges off the step).
— The puncture issue would concern me a bit
–If you will be using the step on a regular basis for a step workout, I would research any effects it may have on your ankles with long term use.
My preference would be for the regular step because it is “tried and true” but there may be others out there who have first-hand knowledge of the Easytone. Those are just my thoughts.
Good luck and enjoy your workouts!
