My boy does that too. Think it's cuz I'm walking around all day and rocking him to sleep. When I lay down and stop moving he wakes up. Lol
Me also my baby girl moves a lot at night but also moves first thing in the morning as well.
That is common. Mostly due to the fact that you are occupied with other things during the day and wouldn't notice all the movements. Some also feel it more when laying down, especially on their back. Some babies are more active when the mother isn't and will instead be rocked to sleep when the mother is active.
