What are some fun ways to incorporate leg exercises into playtime for my baby?

There are various enjoyable leg exercises you may integrate into your baby's playing. Playing "follow the leader" with actions such as marching, dancing, or jumping, playing with a ball and encouraging kicking or rolling it back and forth, setting up an obstacle course with crawling tunnels or stepping stones, and playing "musical statues" where your baby freezes in different leg positions such as standing on one leg are some examples.
