RPG metaphor coming….. this exercises are like a boss fight. Where you have been fighting small enemies that appear randomly on the map, easy, give you little XP and you have to wait ages to level up, you’re always stuck in level 15 and the XP gauge is like a serum with honey in it… now a boss battle comes, it’s hard, you need certain level to at least be a match, you will get game over a lot, but it has lots of XP to give if you defeat it and you’ll level up from level 15 to 20 in this match alone. You just have to keep at it and go defeat some small enemies to get some XP if you need to.
