When a novice chooses equipment in the gym, he can start with a treadmill and a mountaineering machine without the guidance of others. If you want to gain muscle, you can choose fixed equipment, dumbbells and barbells. For newcomers to learn fitness, it is best to start training with dumbbells, and then contact barbells and fixed equipment. Dumbbells have the lowest weight and are more convenient for you to learn movements. Unlike barbells, the empty bar is 20KG, which is very unfriendly to newcomers.
