Lazy 2 year old

Does anyone else have a lazy toddler? My first child was and still is so active and all over the place but my 2 year old is honestly just content to sit on the couch and read his books, watch Blippi, or play quietly on the floor with cars or at his kitchen station. But playtime is always short for him, eventually he goes back to the couch and chills. He likes to color on the iPad (coloring app) and color in coloring books, and just do really laid back activities. He’s not into going outside, he says “it hot mommy” and wants to go inside. People tell me he’s “lazy”… is this a problem? I worry he doesn’t get enough activity but he genuinely just doesn’t want to.

Ps, please don’t come for me about the screen time. Unpopular opinion but if it’s educational content I don’t care about it.
