To gain muscle, you should focus on a combination of resistance training and proper nutrition. Here are some tips to help you gain muscle:

Resistance training: Incorporate exercises that target all major muscle groups into your workout routine. This can include exercises such as squats, deadlifts, bench press, and rows. Aim to increase the weight and/or reps over time.

Progressive overload: Continuously challenge your muscles by increasing the weight or resistance over time. This helps to promote muscle growth.

Adequate rest: Allow your muscles time to recover by taking rest days and getting enough sleep.

Proper nutrition: Eating enough protein is essential for muscle growth. Aim to consume 1 gram of protein per pound of body weight. Carbohydrates and healthy fats are also important for energy and overall health.

Consistency: Stay consistent with your exercise routine and nutrition. Gaining muscle takes time and effort, so it's important to stay committed.

Also, Consult with a trainer or nutritionist for personalized guidance and a tailored plan for your body, goals and lifestyle.

It's important to note that you should also check with your doctor before starting any new exercise or nutrition plan, especially if you have any health conditions.
