I heard that it was an exercise anime. I also heard that it had fan service, cliche moe girls, and hardly any storyline. I watched every episode of this expecting something more. But at the same time... what was I expecting.
The story was simple. A bunch of girls want to be idols so they exercise and talk about how they feel as though they're fat. The smaller ones want bigger boobs and the bigger ones want smaller thighs/hips. They teach you how to exercise.
The art was very cute. Very bright. Lots of fan service but not to an ecchi level.
They focused around one song about smiles and exercise and what not. Also very cute and bright
Characters were incredibly cliche focusing around you- the harem king/queen who is exercising with them.
It was a decent anime. I didn't exercise at all while watching it though, I finished it cause it was short and I was curious to see who the next episode's character would be (I never saw the first season. Whoops.)
