1. Have a clear objective
So why did you buy a cross trainer in the first place?
Did you want to lose weight? Did you just want to work out regularly?
Or maybe you play a summer sport and wanted to cross train so you can work on your stamina all year round?
If you have a clear objective like one of these, then it will be easier for you to stay motivated.
If you're trying to lose weight, then you also need to go on a diet to stay on track and keep your motivation levels high.
You'll see the effects more quickly and you'll feel twice as good.
