1. Pull ups, dumbbell lifts, push ups, etc. can all exercise the biceps, but it needs to be combined with one's own situation to prevent sports injuries.
2. The main function of the biceps is to contract the upper arm, so upper arm flexion and extension exercises are the main focus.
3. For friends who lack exercise, you can start with a smaller weight (such as 5 kilograms) and gradually increase the intensity of exercise.
4. Warm up before exercise and perform relaxation exercises after exercise to prevent sports injuries.
