It is also common for athletes to adjust their weight in preparation for a match.

This allows competition to be held between athletes of similar weight, so we can expect a fair and balanced match.

Training and meal plans for boxing weight control

Boxing requires effective training and a proper diet plan in order to meet the weight limits within your division.

Weight management must be strategic, and it is important to maintain a weight and physical condition that allows for optimal performance without compromising health.

Below you will find a basic training and meal plan for weight control in boxing.


training plan

  1. Cardio training : Cardio training such as running, cycling, and skipping rope are effective ways to increase your endurance and burn fat efficiently. It is recommended that you do at least 30 minutes of moderate-to-high-intensity cardio training several times a week.

  2. Interval training : High-intensity interval training (HIIT) is highly effective for burning fat and improving endurance. Alternate short periods of high-intensity exercise and low-intensity exercise.

  3. Strength training : To improve overall strength and maintain muscle mass, strength training two to three times a week is effective. These include bodyweight exercises, free weights, and machine-based training.

  4. Boxing-specific training : Boxing-specific technical training such as punching bags, mitt hitting, and sparring is also important. These trainings contribute not only to weight management, but also to improving fighting techniques.


meal plan

  1. Balanced diet : Eat a balanced diet consisting of protein, complex carbohydrates, and healthy fats. Include plenty of vegetables, fruits, whole grains, and quality proteins (such as chicken, fish, and legumes).

  2. Hydration : Proper hydration is essential for weight management and improved performance. Drink enough water not only during exercise but also in daily life.

  3. Eat smaller meals : Keep your metabolism active by eating five to six small meals a day instead of three large ones.

  4. Limit your intake of processed foods and sugar : Limit your intake of processed and high-sugar foods to avoid unnecessary fat storage.


Weight adjustment should not be done forcefully in a short period of time, but should be done systematically in preparation for the match.

By combining proper training and nutrition, it is possible to control and lose weight without harming your health.
