I bought something called an air climber, which is basically a cheap compact stepping device with resistance bands for the arms. It was great for a simple home workout, but ended up being flimsy and one of the plastic pedals cracked after a couple weeks of use.
I'm hoping to find something similar in HK, but hopefully more sturdy. Something like this machine, seen on Amazon: http://g-ec2.images-amazon.com/image...39._SY400_.jpg
Anyone seen something like this in HK?
