That’s what I get for more training

I'm not sure exactly what you want to express here - we say "that's what someone gets for X" when we want to express that a bad thing happening to the person was deserved. Someone crashes his car, you say "well, that's what he gets for driving like a lunatic".

So, I started this daily physical training like 2 months ago.

At the time all II was thinking I willould become a god with a perfect body shape.

You'd use "will" if you were directly quoting your thoughts or speech. I thought "I will become a god". Otherwise, the tense changes. I'm not sure what "all" is meant to mean here.

I didwas able to losse a few pounds but I still look (really) fat.

And my body didoesn’t look attractive at all.

During my training time I always findsee more thean one person who is older than me.

We might say "I can always find more than one person", but probably not just "find" here. Difficult to explain why. Alternatives to "more than one person": "at least one person", "multiple people".

Older means a head full of white hairs, shorter than me…

Sounds a bit odd to just say full of white hairs without specifying a part. As if they're stuffed with hair, like a toy animal.

But way much stronger than me in everything!

Or "much stronger", but not "way much stronger".
