without context, "exercise" should be accepted in addition to training.
You need to make sure that both "the" and "a" are accepted when the preposition is ב or ל. Either that or you need to make sure the hover translation specifies which one you are looking for (that's what I thought you were doing).
The difference is in the audio: "le-mis'ada" vs "la-mis'ada".
Same with the ב. Bamisada vs. Bemisada
I listened for it and it sounded like la to me.
Workout should also be accepted
"After the training let's go to a restaurant" must also be accepted. But it's not, I have reported it.
If you utter a command or suggestion to someone including yourself, it would be בּוֹא נֵלֵךְ let us go.
Ah yes, now you say it, it sounds right -- I hadn't thought of that. Thank you
