The Science Behind Habit Formation in Fitness: How to Build Long-Term Exercise Routines

When it comes to exercise, consistency is key to earning its long-term benefits. A mountain of research shows that regular exercise is linked to physical and mental health benefits — from better heart health and lower risk of eight common cancer types, to lower likelihood of mental illness and better quality of life. Yet less than a third of adults participate in enough strength and aerobic training to meet public health guidelines.

Barriers to exercise — perceived lack of time, lack of social support, and lack of access to safe places to move — tend to hold people back from both starting and sticking with a routine. Making fitness an ingrained part of your life may feel daunting, but understanding the science of habit formation can make the process smoother and more sustainable.

What's a habit, anyway?

By definition, a habit is a routine behavior that requires minimal thought once established. Habit formation is built on the habit loop model, which has three essential components: cue, routine, and reward. The cue triggers the behavior, the routine is the behavior itself, and the reward reinforces the loop, making the habit stick.

Here's a simple example with exercise:

• Cue: You see your sneakers and workout clothes sitting next to your keys — set out the night before to remove barriers to making your morning E20 session.
• Routine: When you see your cue, you get dressed, grab your water bottle, and head to the studio.
• Reward: Your completed workout is a reward, building intrinsic motivation and a sense of accomplishment — plus your trainer provides encouragement.

Three science-backed strategies for making exercise a habit

1. Start slow and low, building gradually

Many adults start a fitness routine with big outcome goals in mind. While we love that enthusiasm, research suggests that setting process goals — specific, measurable steps — may be a better approach. Small successes build confidence and create positive associations with exercise. Over time, these small actions can be gradually increased into a consistent routine.

2. Try habit stacking

Adding your new habit to something you already do helps anchor it into your routine and makes it feel less disruptive. For example, book your E20 sessions for each Tuesday and Friday evening so you stop by on your way home from in-office days.

3. Build accountability

Accountability increases your chances of sticking with it: work with a coach or trainer; schedule your workouts in advance (each Sunday, block time to be an exerciser); and track your progress with a tracker, journal, or conversations with a coach to reinforce your behaviors and spot micro wins.

Adopt a flexible, not rigid, approach

Developing a long-term exercise habit is about finding a rhythm that fits your life. Studies indicate that a flexible approach — where you look at your routine over a month rather than stressing about daily perfection — reduces the likelihood of quitting after a missed workout. If you miss a day, double up another day that week or simply pick up where you left off. In contrast, a rigid "all or nothing" mentality makes it easier to skip workouts instead of problem-solving.
