Hi Sheena
Could you tell us what are goals? What types of exercise do you enjoy? what level you are at?
This way we can be of more help.
Personally I started with the Cross Train Xpress Series I was an experienced stepper intermediate to advanced and found the step work challenging.
I would recommend a barbell, dumbells and a step to start with depending on the exercise space available check the specs for both The Step and Reebok step there is a link to Walmart here which sell most of the equipment used in the new series. Check on Behind scenes of the new series on the homepage.
