hi Aleks,
i was doing it as you first described. i created the exercises in the 'add an exercise' area. they were added alright, pictures and all, i downloaded pictures and added my own descriptions. but then when i went to create a workout in the 'create a workout' area, the exercises that were pre-set could be added but my new exercises were visible but couldn't be added. i just tried it again now and it's still a no-go. again, the old exercises (rthat were already on the system) can be added but my new ones that clearly are there as i can see them on the list (pictures and all) cannot even be clicked.
