Library with reusable exercise blocks and supersets

As a coach, I want to be able to save combinations of exercises as a reusable block, such as a warm-up, mobility flow, superset, triset, or cool-down. Such a block must be able to be inserted into an existing training schedule, including the sequence, grouping, instructions, and training settings. The client must be able to execute the entire set as a single workout, without having to start multiple separate templates.
