It is completely possible to practice chest muscles for two months, but the best way to practice chest muscles is to do barbells in groups, and each group does 13 exercises for more than three groups every day, and each group has a rest for one minute. It will be more difficult to practice abdominal muscles, but as long as it is as effective as persistence, abdominal muscles can practice sit-ups, do them in groups, and use abdominal wheels. Eat more foods containing protein and creatine, so the effect will be good.
I wish you an ideal figure as soon as possible.
