When I inquired as to what they were doing, they replied very matter-of-fact,"Getting muscles"
The reason behind this impromptu workout session was that I have been delegating the kids to take out the trash - Jake the actual bag of trash and Jadyn the bottles and cans that need to be placed in the recyclable bin. Well apparently the bag of trash that day was sort of heavy and so Jake decided that they better start bulking up to better prepare them for their chores.
Me? I just smiled and let them continue their workout. After taking a picture of course.
