Hello, I am exercising my muscles with dumbbells now. My way now is to practice and take a day off. Practice chest on Monday, biceps brachii on Wednesday, triceps brachii on Friday and leg muscles on Sunday. As for abdominal muscles, because of their toughness, they can be practiced every other day. Only a good rest can help muscle growth. Prepare to do this exercise for a month, and then increase the intensity and rest for two days. In short, remember that no matter how you practice, rest is the most important link, and you can't always underestimate it. I wish you an early success in fitness!
