It is possible to gain muscle mass without gaining a significant amount of weight of your abdomen, but it may be challenging. Here are a few tips to help:

1. Focus on compound movements. Compound movements, such as squats, deadlifts, bench press, and pull-ups, work multiple muscle groups at once. This will help you build muscle mass in your arms, chest, and back.

2. Eat a high protein diet. Protein is essential for building muscle mass. Aim to consume 0.8-1 gram of protein per day for every kilogram of body weight. Good sources of protein include meat, fish, poultry, eggs, dairy products, and legumes.

3. Eat a calorie surplus. In order to gain weight, you need to consume more calories than you burn. However, you don't want to eat too many calories, or you will gain fat as well as muscle. Aim to eat about 300-500 calories more per day than you burn.

4. Lift weights regularly. In order to build muscle mass, you need to lift weights regularly. Aim to lift weights 3-4 times per week.

5. Be patient. Gaining muscle mass takes time and effort. Don't get discouraged if you don't see results immediately. Just keep following these tips and you will eventually reach your goals.
