Bulk or cut decision-making

Motivation. In fitness and bodybuilding, deciding whether to bulk (gain muscle) or cut (lose fat) is crucial. This decision is based on several factors, including body fat (BF) percentage, muscle mass (MM), and fitness goals. There are many strategies to help individuals make this decision.

For example, according to “Should You Bulk or Cut?”, the decision-making process involves the following rules:

  1. For Men:
    • Cut if body fat percentage is above 20%.
    • Bulk if body fat percentage is below 15%.
    • If body fat percentage is between 15% and 20%:
      • Bulk if muscle mass is low.
      • Cut if muscle mass is high.
      • Maintain if muscle mass is moderate.
  2. For Women:
    • Cut if body fat percentage is above 30%.
    • Bulk if body fat percentage is below 25%.
    • If body fat percentage is between 25% and 30%:
      • Bulk if muscle mass is low.
      • Cut if muscle mass is high.
      • Maintain if muscle mass is moderate.

Problem. Write an algorithm that uses these guidelines to determine whether an individual should bulk or cut. The algorithm takes a person’s gender, body fat percentage, and muscle mass level (low, high, and moderate) as input and determines whether they should bulk, cut, or maintain.

Example Scenarios:

  1. Input: Male, 22% body fat, moderate muscle mass Output: Cut Explanation: For men, body fat above 20% suggests cutting.

  2. Input: Female, 28% body fat, low muscle mass Output: Bulk Explanation: For women with body fat between 25% and 30%, and low muscle mass, bulking is recommended.

  3. Input: Male, 14% body fat, high muscle mass Output: Bulk Explanation: For men, body fat below 15% suggests bulking.

  4. Input: Female, 32% body fat, high muscle mass Output: Cut Explanation: For women, body fat above 30% suggests cutting.

  5. Input: Male, 16% body fat, moderate muscle mass Output: Maintain Explanation: For men, body fat between 15% and 20% and moderate muscle mass suggest maintaining.

  6. Input: Female, 26% body fat, moderate muscle mass Output: Maintain Explanation: For women, body fat between 25% and 30% and moderate muscle mass suggest maintaining.
