1. What is the Russian Twist?

The Russian Twist is a core exercise that targets the abdominal muscles, obliques, and lower back. It involves rotating your torso from side to side while maintaining a seated position with your legs elevated.

2. How Does the Calculator Work?

The calculator uses the standard calorie expenditure formula:

Where:

• \( MET \) — Metabolic Equivalent of Task (3.5 for moderate Russian Twists)
• \( Weight \) — Your body weight in kilograms
• \( Time \) — Exercise duration in minutes

Explanation: The formula calculates energy expenditure based on exercise intensity (MET), your weight, and duration.

3. Importance of MET Values

Details: MET values represent exercise intensity. Russian Twists typically range from 3.0 (light) to 5.0 (vigorous) METs depending on speed and resistance.

4. Using the Calculator

Tips: Enter your weight in kg, exercise duration in minutes, and select appropriate MET value (default is 3.5 for moderate intensity). All values must be positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: What's the average MET value for Russian Twists?
A: Typically 3.5 for moderate intensity, but can range from 3.0 to 5.0 depending on speed and added weight.

Q2: How accurate is this calculation?
A: It provides a reasonable estimate but individual metabolism and exercise form can affect actual calories burned.

Q3: Should I include warm-up time?
A: Only include the actual time spent performing Russian Twists for accurate results.

Q4: Does adding weight significantly increase calories burned?
A: Yes, using a medicine ball or weight plate increases intensity and thus calorie expenditure.

Q5: How does this compare to other core exercises?
A: Russian Twists burn similar calories to sit-ups but engage more oblique muscles compared to crunches.
