Quarantine Activity Calculator

This calculator relies on two primary scientific metrics: the Basal Metabolic Rate (BMR) adjusted via an activity factor, and the Metabolic Equivalent of Task (MET) formula for specific movements. BMR is computed using the Mifflin-St Jeor equation, factoring in your weight, height, age, and sex. This baseline is then multiplied by your lifestyle activity factor derived from work, household chores, and structured exercise. For individual tasks, the calories burned are determined using the standard exercise equation: Calories = (Time in minutes * MET value * 3.5 * Weight in kg) / (200 * 60). This accurately isolates how much energy specific indoor routines consume.

Imagine a 35-year-old male weighing 75 kg, standing 175 cm tall, with a moderate home activity routine. His BMR is calculated, and with an activity factor of 1.375 based on his household work and light exercise, his baseline daily maintenance is roughly 2,150 calories. Suppose he spends 45 minutes doing indoor bodyweight exercises (MET value of 5.0). Using the activity formula, his calorie burn for that specific session is (45 * 5.0 * 3.5 * 75) / 12,000, which equals approximately 328 calories. By comparing this total against alternative routines, users can accurately track their daily energy balance.

To get the most accurate results from your quarantine activity tracking, always update your body weight and height measurements accurately. When selecting MET values for household chores or extra activities, be honest about your exertion level rather than overestimating intensity. Finally, use the comparison features to experiment with different daily schedules, helping you find an optimal balance of movement even when confined indoors.
