• Actions should be standard: Non-standard movements can easily cause damage to joints and muscles.
• The weight should be appropriate: Overweight dumbbells tend to strain muscles, and dumbbells that are too light cannot achieve the training effect.
• Warm up is essential: Before the start of the exercise, warm up carefully; after the exercise, be sure to do a good job of relaxing activities.
• Exercise in moderation: If you blindly pursue the amount of exercise, excessive exercise will occur, and you should pay attention to adjustment and rest.
• Be in a good mood: A good mood can often get twice the result with half the effort and bring unexpected results.
