Fitness goals are important on several counts. They hold us accountable, expand our definition of possible, and encourage us to push through temporary discomfort for longer-lasting change. But figuring out how to set fitness goals you’ll actually want to attain can be part art, part science.

Mark DiSalvo, NYC-based certified strength and conditioning specialist, explains it this way: A good fitness goal can be “your North Star when you have bad days,” he tells SELF. In other words, a goal, if thoughtful and well structured, can give you the extra incentive to keep going when motivation wanes, or when life otherwise gets in the way.

The problem is that during this time of year, it’s easy to get caught up in the rush of New Year’s resolutions and set goals that are too lofty, unsustainable, and otherwise unrealistic. We then fail to achieve them and feel worse about ourselves than before we started. This year, to avoid that detrimental downward spiral altogether, we asked DiSalvo and four other top trainers to share their advice for doing fitness goal setting right. Here, 11 of their tips for enacting real, positive change.

1. Focus on one goal at a time.

When it comes to setting a fitness goal, “one of the biggest mistakes is that people try to do too much at one time,” Kellen Scantlebury, D.P.T., certified strength and conditioning specialist and founder of Fit Club NY, tells SELF. Perhaps you want to hit the gym every day, cut out added sugar, and get at least eight hours of sleep a night. Trying to tackle that much at once is essentially just setting yourself up for failure. With so many things to achieve, “people get anxious, and if they didn’t do one thing, they feel like a failure,” says Scantlebury. This can lead to negative self-talk that lowers your chances of achieving any of the goals.

Instead, pick one thing you want to crush—like, doing a pull-up, or completing your first-ever 5K—and channel your efforts into achieving that before exploring another goal.

2. Make it your own.

It can be easy to scroll through the ‘gram and feel inspired-yet-envious by images of the super fit. Yet basing your own goals off of what you see others achieving is neither productive nor practical.

“When we are bombarded by images of what fitness should look like and how we should do XYZ, it can be hard to identify what’s good for you,” Tony Vidal, NYC-based certified strength and conditioning specialist and master trainer with fitness app POPiN, tells SELF. Certain things that top athletes can do—run a marathon, do 100 push-ups, master the most challenging yoga poses—“may be great for them, but it’s not metric that everyone should be measured by,” says Vidal. In other words, your goal should be your goal—something that you personally are excited about and realistically able to achieve—not someone else’s.

3. Make it measurable, specific, and time-bound.

Having a measurable goal allows your to track your progress, says
