This calculator estimates calories burned during sit-ups based on:

1. Body Weight: Enter your current weight. Calories burned are proportional to body weight.
2. Number of Sit-Ups: How many sit-ups you performed.
3. Sit-Up Pace: Select the intensity of your sit-ups. This determines the MET value (Metabolic Equivalent of Task) and estimated duration.
   • Slow/Light: ~15 sit-ups/min (MET: 2.8)
   • Moderate: ~25 sit-ups/min (MET: 3.8)
   • Vigorous: ~40 sit-ups/min (MET: 8.0)

Formula: Calories/Min = (MET * Body Weight in kg * 3.5) / 200. Total duration is estimated from number of sit-ups and pace.

Tips for Accuracy:

• Be honest about your pace.
• Ensure proper sit-up form for effectiveness and safety.

Disclaimer: This is an estimate. Actual calories burned can vary based on individual metabolism, form, and other factors. Consult a fitness professional for personalized advice.
