How do you lvl up Pokemon fast in daycare?

walk out of the daycare take 2 steps down then get on match bike and go left all the way until you stop then go right and keep doing. that. my 30 year old grew 67 levels and all i did was go back and fourth 6 times

I completely do not believe that, but i have not yet tried it. I put my finneon in, saved, then shut of my ds, turned it back on and changed the date to a few days in the future, then restarted my ds, loaded up the game and my finneon's level had gone up. XD woot, but please, do try the first answer!!! It may work!!!!

actually none work but the first won i did it six times and my lvl 50 lugia went up one but its exp was pretty high and im sure it doesnt work cause with that lugia was a lvl 30 um togepis evolvation and the second one i put it in and went 89 YEARS in the future and NOTHING happened then i tried days to see if u kno and NOTHING happened i just do stuff but i beat all the gyms and i fail the Pokemon league because of my weak Pokemon so ill lvl them in daycare too and that's y i found this question

also you can get on your bike outside the day care center and then just keep going up and down through goldenrod, i did that 50 times and my Pokemon has gone up 29 levels already
