A little can make a lot. Here too, the way to have beautiful breasts is to exercise for a few minutes every day. It's simple and practical
600g dumbbells
Book
Stand with your feet shoulder-width apart, clench your hands to the sides of your chest, point your feet, and swing your chest back with your elbows while leaning forward. Repeat 20 times.
Cross your hands, hold them parallel to your shoulders, and push them to the left and right 15 times
Bend the elbows of your hands into a round shape at the chest, rise up to the forehead, and return to the original position 15 times
Bend your elbows, fold your hands together, and slowly lift them upward, over your head and without separating your hands, and return to the original position 15 times
Hold the bell in each hand to the left and right, parallel to the shoulder, for 5 seconds, repeat 15 times
Lie flat on the ground, legs straight, hands hold the bell, hands left and right, do not touch the ground, lift up again, 15 times
Sit one third of the way on the bench and hold the book between the palms of your hands, extend your arms straight in front of you, and repeat 15 times
The number of exercises each time need not be too much, but to insist on doing every day, it will be very effective.
