What it means: "Is your body composition changing? That's what is most important," says Holly Rillinger, a master instructor at Flywheel in NYC. If your clothes aren't fitting better, you might just be spinning your wheels at the gym—and not in the way you want.
How to adjust: Keep track of what you are eating and see if you need to adjust your diet, says Rillinger. If you don't already strength train, add some weights to your routine to build fat-burning muscle. Otherwise, consider working in a high-intensity cardio session to your plan to blast calories—research from Canada found that sprints can help reduce body fat.
