For better or worses, trainings is (are?), coming into more freakuent use.
I, well Google, found:
"Trainings & Conferences, California Advocates for Nursing Home Reform
"Advanced Trainings World-Wide
Offering a variety of bodywork trainings
"Laban's addiction specific chemical dependency home study trainings
"Meditative Trainings
"Mindfulness Trainings..."
I wouldn't use the word,
or the word "bodywork" for that matter.
