Visual demonstration on ‘right forms and positioning’ of workouts (by muscle groups areas). Perhaps a little GIF or a 15 secs video or animated vid of the right form and positioning of workout. This solves problems for a lot of people who just use the equipment in the incorrect forms, that may cause muscle injury etc. A solution where people could search for a particular workout or by muscle group and learn from the little vid how to perform the exercise the right way.
