Especially the upper body has changed a lot, because the upper body was very fat when I lost weight before, but I really lost weight after doing dumbbell exercise for two months, especially in my abdomen. And this set of movements also involves a lot of leg movements, so my thigh latitude has also lost a lot.
This exercise lasted almost more than 30 minutes. It's really tiring to say that I'm tired, because I paused for four or five times the first time when I danced Duoyan Zheng's dumb bell exercise, because two portable dumbbells were really difficult to lift, but I got used to it after a long time.
In the first month, I did Duoyan Zheng's dumbbell exercises once a day. Since the second month, I have increased my exercise. I did it again in the morning and again in the evening, and I really lost a lot of weight. Of course, I don't have to do Duoyan Zheng's dumbbell exercises. I can try many other types of dumbbell exercises.
But the choice of dumbbells must be appropriate. I bought two dumbbells of 1.5kg, and I feel a little hard. I suggest novices buy dumbbells of 1kg.
