Never miss a date with the treadmill, but not seeing results on the scale? These mistakes on the machine may be what's hindering your weight loss. Not pushing yourself: If your treadmill routine always involves catching up on the latest tabloid magazine or talking to your workout buddy, then it's time to stop being distracted and focus on your workout instead. While a slow, steady-state cardio always should have a place in your routine, if you want to see results, you'll need to start increasing your speed. The upside? You'll spend less time at the gym and burn more calories in the process.
