The abdominal muscles are usually divided into sections: upper, middle and lower . In fact, all the “cubes” work together. They are divided into departments CONDITIONALLY. When they say “the lower press is working”, this means that it receives the greatest load. But the middle and upper ones are also included in the work.
In fact, it doesn’t matter where exactly you work out, in the gym or at home. Abdominal exercises are performed in the same quantity and using the same technique. Only the training program itself differs, but not the number of approaches or repetitions.
