To safely increase your level of physical activity, begin by setting small, manageable goals to avoid injury and burnout. Gradually increasing intensity, duration, and frequency of exercise allows your body to adapt comfortably. Incorporating a mix of aerobic, strength, and flexibility workouts can enhance overall fitness while preventing monotony. Additionally, listening to your body’s signals for rest is vital. Always consult a healthcare professional before making significant changes to your exercise regimen, especially if you have any pre-existing conditions. Ensuring proper warm-ups and cool-downs reduces the risk of injury.
