Is punishing players and making them do gassers more for youth football? Do they not waste their time doing that at the higher level?

When I was in hs our coach always made us do gassers and bear crawls. I thought all teams do it but I was surprised how much they don't the higher up you go. I don't know if its more for hs because kids goof off and its more like daycare than actually practicing.

I was so used to doing them that I was surprised when I didn't have to anymore. I think coaches higher up just expect you to perform , be more mature, and if you have an attitude you'll just get kicked off.Just curious.
