Some schools in Canada use exercise bikes to help kids focus on lessons, though there's little research on this https://www.theglobeandmail.com/opinion/stationary-bikes-in-...

My own anecdote is it seems to work, 20-30mins of high intensity bike riding followed by a shower and somehow I can sit and do 2-3 hours worth of focused work on a math text without my mind jumping around distracted in random thoughts or becoming bored.
