But for most native speakers of English, training is an uncountable noun. The Cambridge online dictionary defines it as ‘the process of learning the skills you need to do a particular job or activity’ (my emphasis). This makes it less likely to be used as a plural.
For a countable unit of training, English prefers such compound nouns as training course, training day or training session:
So the phrase a little training, used by a native speaker, would mean ‘some training’ and not ‘a small-scale training course/session’.
Actually, there are quite a lot of instances on the web of trainings used by natives. The majority seem to be from those who offer such ‘trainings’ professionally; a substantial proportion are in the area of ‘new age’ practice/therapy. Among the general population, however, I think it’s fair to say that training is uncountable.
