When you get to the mission "Getting Stronger" in Chapter 3, your character will need to complete six training exercises, or mini-games. You can mess up and get the timing down during this point. Afterwards, you'll participate in an Ironman-esque event where you do all of them together (and it's random) and it speeds up. There will be montages, as reference to the Rocky movies.
In order to obtain this trophy, you can't miss any targets or any penguins or mess up in the mini-games. If you skip a target, like in Slingshot mini-game, that counts as a miss. If you miss something or mess up, restart the checkpoint, which means you'll have to restart the full Ironman event. Must complete the full training montage without any mess ups to get trophy.
Some information and tips:
- It starts out slow with more requirements for each mini-game completion, and as you complete more, the reqs become less but the speed increases, including penguin drop rate during the Homerun mini-game.
- Press back on the left stick at the end of mini-games or during a montage in case the next mini-game is the Slingshot so you can load a penguin faster.
- During Slingshot, when you pull back on left stick, you can move it to sides to aim, as the pteros come from both sides.
- The difficulty for the egg balance mini-game is much more difficult later in the event, if it appears.
