Low-impact exercise usually refers to activities with less impact on the body and less difficulty. Here are some common low-impact actions:

1. Walking/jogging: Walking and jogging are simple aerobic exercises with little impact, which can improve heart and lung function and burn calories.

2. Yoga: Most yoga exercises are slow and gentle, which has little effect on the body and can improve flexibility and body control.

3. Swimming: Swimming is also a low-impact whole-body exercise, which is very suitable for people with joint problems or insufficient oxygen intake.

4. Cycling: Cycling has little impact on the body, but it can still reach a fairly high level of heart rate and energy consumption. Low-level movements in fitness, such as push-ups and sit-ups, have far less influence than other high-level movements.

5. Lightweight dumbbell exercise: Using lightweight dumbbells to exercise, such as heel lifting and side lifting, can enhance flexibility and muscle strength, but compared with high-intensity strength training, the impact is relatively low.

Tai Ji Chuan: Tai Ji Chuan is a traditional martial arts sport, with little exercise and slow pace. Although some movements are more complicated, the impact is much smaller than other high-intensity martial arts training.

7. Pilates: Pilates is a low-impact whole-body exercise, which improves the balance of core muscles and body by controlling breathing and muscle contraction.

In short, low-impact exercise is mainly aimed at those who want to reduce joint load and are weak. These exercises can effectively improve physical fitness, reduce the risk of injury and help improve the quality of life.
