If you want to practice your chest muscles, just lie flat with two dumbbells and lift them horizontally. If you are practicing biceps, stand with two dumbbells and lift your back without moving. This effectively helps to train your back and chest muscles. When you can lift it easily for 20 times, you will gain 65,438+00 pounds. You should practice your biceps and chest muscles every day until you feel unbearable, so that your muscles can become big and powerful.
