Summer Athletics

The easiest way to do this is to go to Competition>Free Cup then add "ARCHERY 70m COMPOUND." Then, add the rest of the events to the list (you won't actually have to play them all). Click continue, then you will start with 9 boosts. In Competition mode, it is much easier to control the bow when compared to Single Event mode. I got it on my 3rd try using this method, whereas I tried for over an hour in Single Play and couldn't get the hang of the way the bow would try to move against you. If you happen to mess up, just press Start, then go to Quit and go back to Competition>Free Cup and it will have your settings saved, and you can just press continue right away again. You need to get all bullseyes (10 points each) in all 3 rounds to get the achievement.
