The stepper is like a little device (that weights quite a lot), made out of what feels like iron. It has 2 platforms for your feet in a rugged well made plastic (but is still soft enough to use barefoot, so you can choose barefoot or with shoes). Attached to these platforms are these 2 air pistons, which provide the resistance (they are not adjustable), and these connect to the base unit. There is also a sort of counter which counts the time, calories burnt, and steps taken (and if i think you can do program exercises, but i never bother). Anyway, the way it works is that you sort of shift your weight from one leg to the other, similar to walking, and this pushes the air pistons down, and that counts as a rep. When the machine is cold, it feels quite stiff and strong, and provides a great workout! But sadly, do too manny, or do them too quickly, and the pistons become very hot! this makes them not as stiff and rigid (i presume because the metal in them expands), and the workout becomes very easy. for this reason this is not the sort of thing you can do every day to get fitter indefinitely. You kinda reach the machines peak (i am not the fittest of people but after about a week of using this, i pretty much max it out). This is really annoying, as say if you spend 30 minutes at full pelt on it, it becomes a pointless exercise until it cools down again... not very impressive reallym especially for something this bulky and expensive! Overall then, this is probably ok if you have really low fitness, and need help with things like walking, or are very unfit (but then i think this has a maximum weight as well???). Otherwise, i would say just go walking outside, or get a treatmill, or a proper crosstraining machine. This just ends up feel a bit gimicky, but the one thing that is very good about it is that its pretty silent, so its good for when watching tv (unlike almost any exercise equipment i know, weights get annoying, treadmills are too noisy, etc etc). Apart from that, not sure i can honestly recommend this
As part of my recent get fit fad that I am going through, I recently decided to purchase this Step Aerobic machine figuring that I could use it while I read my Kindle in my lounge; combining two interests at the same time! It is small, compact but surprisingly heavy and basically requires you to step on and off each pedal, triggering the pistons to pump up and down. A computer display on the unit keeps track of how many steps you have taken, how many calories you have burnt off etc etc... This is a great little device because you can work out without actually thinking about what you are doing and forgetting all about it (almost) while you do something else. My wife has used it watching telly and, like I say, I have used it whilst reading my Kindle for quite long periods of time. Though be warned.....your legs are seriously going to ache if you do this for too long and the experts DO recommend you consult your local Doctor if you are going to start doing A LOT of strenuous exercise! One thing I have noticed is that, after extensive use, the pistons begin to hiss a little. Also the underside of this Stepper does get quite hot so please be careful and allow it to cool down a bit before you attempt moving it into a corner. Despite what I have read on Amazon, I find the computer display to be fairly accurate and have had no problems with it though I do tend to have to take its word for how many steps I have taken, calories burnt as what do I know about such things?!? Personally, I really like this and though at £95 you can get cheaper brands and models, I bought this on a friends recommendation and so far I am very impressed! It fits nicely out of the way in a corner when its not being used, only to get pulled out when I decide I need a work-out. And the fact that I can combine this with my other interests only adds to its attraction! This is definitely a good buy for me!
