You know how you get set in your ways with the order you do things at the gym? I for one always did my cardio first before weights. My tip today is to switch things up. If you're like me, why not start on the weights first, then move on to cardio? I have switched the two around. By doing this, I feel stronger since my muscles aren't tired out by the cardio first, therefore, I am able to lift more.
Chopping and changing your routine will prevent you from getting stale and bored!
