These notes combine advice from 17 reviewed passages across 14 workouts.
The body adapts with repeated exposure. People respond differently to the same movements, so the reaction you get is not the same for everyone. Inverted positions can feel confusing at first, but the body becomes familiar with them as practice continues.
A normal person may faint at about 4 G, and a backflip is around that level. A double backflip reaches around 6 to 7 G, which is why most people black out. Twisting gymnastics movements can bring a person close to fainting, which is why very few people reach that level. Astronauts, who endure the highest loads, withstand around 8 to 9 G with special training.
Sudden movements can cause dizziness, and older people who do a movement suddenly experience it. A person unaccustomed to such movements can get dizzy or fall when doing them fast, and people over 40 or 50 who are not used to them can have the same reaction, even to bending down. Feeling the head go and come back after a fast movement is normal.
Turning in place can cause a head-related problem in some people. A full, dense training session can leave the head spinning, and vision blurring during this work is a normal reaction that shows the body is responding.
Repeated spinning practice can cause severe nausea at first. One person reported vomiting for the first six months of spinning practice before the body adapted, and continuous spinning is associated with frequent vomiting during the first three to four months. Spinning sessions that last for hours can lead to vomiting. Once the body gets used to rotation, the nausea no longer occurs.
The body gets used to these forces by doing the movements. Moving between surfaces, such as from the floor to a bar or to sand, can disorient the body until it adapts to the new surface.
Get the body used to these forces with regular practice.
When dizziness appears in handstand, check whether you held your breath.
The mind should be clear when training.
In his own training, the coach feels stronger on days when he trains spinning on his head.
In his own training, doing the movement on sand completely confused his head.
In his own experience, he had nausea for about two weeks while his head was spinning.
Dizziness in turning movements was his biggest problem, and his turning capacity grew from about five repetitions to thirty or forty with repeated practice.
