I will paste what I answered in a similar thread from !anime@ani.social a little while back that might be of interest to you:
I usually watch an OP once for a show and then skip it each time afterwards. That being said, there are a handful that I remember making the choice to always watch each episode. In no particular order:
- (NSFW) B Chiku Sentai SOX - “SHIMONETA: A Boring World Where the Concept of Dirty Jokes Doesn’t Exist” - I always laughed at the visuals of this more than anything. This show was wild.
- Onegai Muscle - “How Heavy Are The Dumbbells You Lift?”
- Idol - “Oshi no Ko”
- Zeitaku na Saji - “Campfire Cooking in Another World with my Absurd Skill”
- GO!!! - “Naruto”
“How Heavy Are The Dumbbells You Lift?” just jumped up a few places in my watchlist. Looks fun to watch
I wrote a little bit about it a while back when I posted a clip for Thanksgiving. Overall, it is a piece of lighthearted fun that was perfect for watching an episode before bed. It also tried to be educational about how to properly work out, while at the same time using those educational segments as an excuse to include a bit of ecchi.
