Как перенести заказ по умолчанию в Django

У меня есть две модели, Exercise и Workout. Когда я добавляю список упражнений в таблицу Workout, они добавляются в алфавитном порядке. Я не хочу этого. Я использую ajax для отправки списка exercise_id в нужном мне порядке, затем в своем views.py я получаю упражнения по id и добавляю их в таблицу workout. Я хочу сохранить порядок добавления упражнений. Как мне это сделать? Ниже приведены фрагменты моего кода.
