Variation and transfer in a fitness program; changing exercises and applying gained skills.
Variation in a fitness program on day 3 could involve changing the types of exercises, equipment used, or intensity levels to prevent plateaus and keep the body challenged. For instance, switching from running to cycling or using resistance bands instead of weights.
Transfer in day 3's fitness routine may come into play when skills or endurance gained from previous days' workouts are applied to new exercises. An example would be improving balance from yoga sessions helping with stability during weightlifting.
