Dumbbell: I can do all kinds of exercises to exercise muscles in different parts, and chest muscles are the fastest. I am thinner. Each group 12 birds, 3-6 groups at a time (better mental state).
Birds leaning upward: each group 12, 3-6 groups at a time (better mental state). This exercise is the upper part of the pectoral muscle.
Push-ups can also be exercised, and the number can be increased a little. Note: Your arms should be as relaxed as possible and as flush as possible with your shoulders.
abdominal muscle
Personally, I think this is better. It varies from person to person. My belly fat is getting less. I do three groups every day, one group of 20, with an interval of 5 minutes, plus 60- 100 sit-ups. I feel much better. I divided it into three groups, 33 in each group. The last group couldn't do it, and then I did less. The effect is very good. Remember not to eat too much! When you sit up, control your body when you lie down, and then continue. This is better.
