Hello, doctor.
My body type is slender, with a BMI of only 17.84, but I would like to increase my strength.
I am considering doing some weight training, such as lifting dumbbells or doing push-ups.
Can someone with a slender physique engage in these types of training? Thank you.

Dear Kai-Kai,
Hello, your BMI is only 17.84, which is below the normal range of 18, indicating that it is on the low side.
I recommend that you eat a bit more to gain about 2 kilograms.
If you want to increase your strength, you can engage in activities you enjoy, such as playing sports, swimming, or cycling.
The most important thing is to maintain a consistent exercise routine.
As for weight training, there is no rush; it is best to start once your BMI is above 22.
Thank you.
Wishing you safety and health.
Sincerely,
Dr.

More Info


Building muscle with a BMI of 17.84 is certainly possible, but it requires a careful and balanced approach. A BMI of 17.84 indicates that you are classified as underweight, which means your body may not have enough energy reserves to support intense training or muscle growth. However, with the right strategies, you can safely engage in strength training and work towards increasing your muscle mass.


Understanding Your Body
Before diving into a workout regimen, it’s essential to understand that muscle building requires not only resistance training but also adequate nutrition. Your body needs sufficient calories and nutrients to repair and grow muscle tissue after workouts. Since your BMI is low, it’s crucial to focus on gaining weight in a healthy manner before heavily engaging in weight training.


Nutrition is Key
1. Caloric Surplus: To gain weight, you need to consume more calories than you burn. This means incorporating calorie-dense foods into your diet. Focus on healthy fats (like avocados, nuts, and olive oil), lean proteins (such as chicken, fish, eggs, and legumes), and whole grains (like brown rice, quinoa, and oats).

2. Protein Intake: Protein is vital for muscle repair and growth. Aim for a protein intake of about 1.2 to 2.0 grams of protein per kilogram of body weight. This can come from both animal and plant sources. Foods like chicken, fish, eggs, dairy, beans, and lentils are excellent choices.

3. Frequent Meals: Eating smaller, more frequent meals can help you increase your caloric intake without feeling overly full. Try to include a source of protein in each meal and snack.

4. Hydration: Staying hydrated is important, especially when engaging in physical activity. Water supports overall health and aids in digestion and nutrient absorption.


Strength Training
Once you have established a nutritional foundation, you can begin incorporating strength training into your routine:
1. Start Gradually: Begin with bodyweight exercises like push-ups, squats, and lunges to build a foundation. Once you feel comfortable, you can gradually introduce weights, such as dumbbells or resistance bands.

2. Focus on Compound Movements: Exercises that work multiple muscle groups, such as deadlifts, squats, and bench presses, are effective for building muscle mass. These exercises stimulate more muscle fibers and promote overall strength.

3. Consistency is Crucial: Aim for at least 2-3 strength training sessions per week. Consistency will help you see progress over time.

4. Rest and Recovery: Allow your muscles time to recover. This means incorporating rest days into your routine and ensuring you get enough sleep each night.


Monitor Your Progress
Keep track of your weight and strength gains. If you find that you are not gaining weight or strength after a few weeks, consider consulting a healthcare professional or a registered dietitian. They can provide personalized guidance based on your specific needs.


Conclusion
In summary, while a BMI of 17.84 presents challenges, it does not preclude you from building muscle. Focus on a balanced diet that supports your training, gradually introduce strength exercises, and ensure you are consistent with your efforts. With patience and dedication, you can achieve your goal of increasing strength and muscle mass. Always listen to your body and consult with professionals if you have any concerns about your health or training regimen.
