What is Physical Activity?
Physical activity is any movement produced by your muscles that uses energy. From everyday movement like walking, taking the stairs, and doing chores, up to structured exercise like weightlifting, running, or riding a bicycle. Theia captures this in a few ways:
Steps measure your overall daily movement
Active minutes measure time spent at higher effort - the movement that raises your heart rate and breathing
Activities are the individual exercise sessions you or your device log
Together these show both how much you move through the day and how much focused activity you get.
Why Activity Matters
It's easy to think of exercise mainly in terms of fitness or weight, but movement is one of the most powerful levers for metabolic health specifically. Here's how it connects to the same systems tracked elsewhere in Theia:
Insulin Sensitivity & Glucose Uptake: Skeletal muscle is the body's largest site of glucose disposal. When muscles contract during activity, they draw glucose out of the bloodstream through a pathway (GLUT4) that works independently of insulin.
Post-Meal Glucose Control: Activity in the window after eating blunts the glucose spike that follows a meal. Research on short post-meal walks shows meaningfully smaller glucose ruses compared with staying seated - a small habit with a potentially large metabolic effect.
Long-term Metabolic Protection: Regular activity improves the body's insulin response over time, supporting healthy glucose regulation and lowering the risk of progressing toward diabetes or type 2 diabetes.
Energy, Mood & Sleep: Activity supports stable energy, mental wellbeing, and sleep quality - which in turn feeds back into metabolic health.
What Do the Research and Guidelines Say?
It helps to know where common activity targets come from, and where they don't.
The 150-minute recommendation. The most widely used activity target for adults comes from the World Health Organization: adults should aim for at least 150 minutes of moderate to vigorous intensity activity per week. Think of brisk walking, cycling, or anything that gets you moving a little out of breath. This is the figure that Theia represents in your Activity view as the 150 Min Recommended mark, and it works out to a very manageable rhythm: roughly 30 minutes on most days of the week.
A few things make this target more approachable than it first sounds:
Any activity is better than none. The steepest health gains come from simply moving more when you're starting from little.
All activity counts. It doesn't need to come in long, unbroken sessions. Shorter bursts throughout the day add up toward the same total.
More can add benefits. 150 minutes is the floor, but certainly not the ceiling. For most people, additional activity continues to show benefits.
At Theia, your goals are personal. These guidelines are general population reference points, not personalize prescriptions. The right step and activity target depends on your health, history, and goals. Instead, patients and providers set targets together, and Theia tracks consistency against them.

How Theia Shows Your Activity
Within your Activity view:
Avg / Day is your typical steps or active minutes over the selected period
30+min Days counts how many days reached at least 30 minutes of activity. This can be used to measure consistency, alongside the step goal consistency bar.
The weekly activity bar compares your week of activity against the general 150-minute reference and caps at 100%.
Use the 7D / 14D / 30D selectors or the calendar to change time window. Manage to check your data source and last sync, and Goals to set targets.
