1. Do nothing and everything at the same time

2. Probably make myself look more like escanor and luther strode

3. Become a tank by making damage heal me and damage the attacker

What would I do? Well, that's simple. I would work out later and get the results now. I'll also use powers I don't have and skills I don't have to do things I can't. ¯\_(ツ)_/¯

And yes, I would enhance my appearance since there isn't a reason not to.

Yeah, I think I'll stick with knocking people down.

Instant effects for proficiency, like some skill gaining exp

Probably some other random stuff

Not sure why would I want to change or enhance my appearance, though would be funni

P i n g p o n g or wack a mole, increase knockback by maybe 20 folds

Of course change my appearance and work out for 1 minute and get absolute condition cause why not? The other stuff are like the others^^^^

Smoke to gain better lungs, be lazy to strengthen my body, drink alcohol and hit myself in the head to enhance my mind, go swim in lava to cool off, swim in toxic waste to cure cancer(I don't have cancer), dunk myself in acid to make my atoms stronger,

Those are some great responses!

Well, Suddenly I will be able to recall everything I've ever learned and experienced with clear accuracy. Now this is where it gets very tricky I don't have superpowers but for some reason, I'm able to use powers, abilities, and skills I've never had proficiently.
