We understand your concerns
I went through your description. I feel you should have mentioned your age and other physical conditions. If there is no physical problems, then you should not worry.
, as you are aware, is very common. But you feel that you have more of it in intensity. The basic reason for the dizziness
is imbalance. The fluid inside your ear is keeping your balance, and when it is swirled or disturbed, that creates imbalance or dizziness for some seconds and then dies down. There are so many other reasons which may not be worth mentioning here.
trainer is supposed to be trined in these imbalance aspect. He should be able to clear your problem. Or else, if you cannot tolerate, do consult a general physician for further advice.
Hope this answers your query. Available for further clarifications.
