First, buy a pair of dumbbells. Why not buy barbells and weight-lifting beds? Because it is not necessary for a novice, and you can't push it, you are still a high school student with financial problems! It costs more than 100 yuan to buy a pair of dumbbells. We bought 25KG detachable rubber, and two of them were 100KG. You didn't tell me your height and weight. Try 65,438+00-65,438+05 kg yourself and see if you can lift it. If you can't lift it, try 7KG. You're still developing. Just lie down. Every night, if you have time, take 45 minutes to practice, but your muscles will be very painful. Be patient. If the muscles are sore, they will stop. After a few days of rest, the pain will continue. If it hurts, it means that the place where you practice is fat. You can feel your strength increase. No matter how many days you practice a month, you should supplement100g protein every day! You need to make up for this because you are too thin! When you can practice 25KG dumbbells, you can buy a barbell and bench press. Come to me again if you can! Practice according to the video on the following website! There are other questions you can ask me. By the way, eating more protein-rich food after practice will also help to grow muscles.
