Your weight can increase after starting strength training because your muscles store more water while recovering from workouts. This is a normal response to exercise and does not necessarily mean you are gaining fat. Give your body time to adapt and monitor your progress over several weeks.
One reason your weight is increasing could be that your muscles are storing more glycogen. Glycogen is the stored form of carbohydrates that your body uses for energy during exercise. Each gram of glycogen is stored with several grams of water which can increase your overall body weight without meaning you have gained fat.
If you have recently started strength training you might notice that your weight increases even when your body looks leaner. This can happen because you are building muscle while losing some body fat. Your weight alone cannot tell you whether your body composition is improving so pay attention to your measurements and how your clothes fit.
If you are lifting heavier weights every week your muscles may gradually become bigger and stronger. Muscle growth can contribute to an increase in body weight even when your fitness is improving. Remember that building muscle usually takes consistent training over time so a sudden increase over a few days is more likely to involve water and other short term changes.
Your weight might increase because you have started eating more carbohydrates to support your workouts. Carbohydrates help replenish muscle glycogen which provides energy for strength training. When glycogen stores increase your body also retains more water so the scale may rise even though this is not the same as gaining body fat.
Another reason for weight gain is eating larger portions after exercising. Many people feel hungrier after strength training and may unintentionally consume more calories than they burn. Try planning your meals ahead of time and include protein fiber rich foods and balanced portions so you can recover without consistently overeating.
If you have started taking creatine your weight may increase because creatine can increase water stored within your muscles. This is a common effect and does not automatically indicate fat gain. Creatine can support strength and training performance but you should understand that the scale may change even when your body fat has not increased.
Your weight can fluctuate because of the amount of food and fluid still present in your digestive system. Eating larger meals or increasing your carbohydrate and fiber intake can temporarily increase the number on the scale. This is normal and does not necessarily reflect a lasting change in your body fat.
If you are a beginner your body may respond strongly to the new demands of strength training. Your muscles need time to adapt to unfamiliar exercises and challenging sessions. Temporary soreness and water retention can affect your weight during the first few weeks so focus on building a consistent routine rather than expecting immediate changes on the scale.

You may be gaining weight because your strength training program is helping you build muscle while your fat loss is progressing more slowly. This is especially possible if you are new to resistance training or returning after a long break. Make sure your workouts are progressive and your nutrition matches your goals before deciding that your routine is not working.
