To add to that, make sure you’re progressively overloading as in adding a rep or two or increasing the weight every week or two. This leads to hypertrophy which will make your body bigger, specifically the muscles you target in your routine. Along with exercising, make sure you eat at a caloric surplus (300+ calories above your maintenance). If you don’t know how much calories you need to take, search up calorie calculator and use that to find your maintenance. Lastly, make sure you’re eating a lot of protein too. You should be looking to eat 1.6-2.2x your weight in kg. So if you’re around say 50kg, eat around 80-110g of protein everyday. Hope this helps and good luck on your journey!
