Purpose: This study looks at how certain body markers (biomarkers) change in college students after short, moderate exercise. Biomarkers are substances in the body that can show how healthy you are. We compare students who exercise regularly with those who don't, and also look at their mental health.

Study Details: Students will have two groups: active and sedentary (not much exercise). We will measure things like blood sugar and heart rate. Students will exercise on an elliptical machine for 12 minutes. We'll take blood samples and ask about what they ate and how they got to the study. They will also fill out a mental health questionnaire.

• Study is for students aged 18-34 at the investigator's university.
• Participants must be willing to exercise and have blood samples taken.
• Avoid if allergic to nuts or lack transportation to the lab.

Note: Participation means you will need to visit the lab, exercise, and give blood samples. This helps us learn how exercise affects health!
