And I’ll work out tooreally hard. And I’ll work out really hard.

I changed the too to something appropriate but I don’t think that the sentence needs an adjective since hard is a very intense word to describe something already.

And I’ll work out tooreally hard. And I’ll work out really hard.

"too ____" means "too much of something", and is a bad thing. For example, "This class is too hard" means "it's very hard for me, and that's not good".

And I’ll work out too/very hard. And I’ll work out too/very hard.

And I’ll work out toovery hard. And I’ll work out very hard.

Andlso I’ll work out too hard. Also I’ll work out too hard.

I nNeed to gGo on a dDiet. I Need to Go on a Diet.

It’s getting hot weathter and hotter these days./The weather’s getting hotter these days. It’s getting hotter and hotter these days./The weather’s getting hotter these days

Both things I wrote down are correct. It just depends on the sentiment you want to express.

It’s getting hot weathter these days. It’s getting hotter these days.

You can say "It's getting hotter these days" or "The weather is getting hotter these days".

It’The weather is getting hot weathter these days. The weather is getting hotter these days.

It’The weather is getting hot weather these days. The weather is getting hot these days.

You can say various things. "It's getting hot these days" would also be fine.

It’The weather is getting hot weather these days. The weather is getting hot these days.

So, I was wearingore a short sleeve and short pants today. So, I wore a short sleeve and shorts today.

Since you’re talking about something that you already did, you’d use the past tense.

So I was wearing a short -sleeved shirt and short pants today. So I was wearing a short-sleeved shirt and short pants today.

So I was wearing a short sleeve shirt and short pants today. So I was wearing a short sleeve shirt and short pants today.

And I felt moreally uncomfortable in athe shorts. I felt really uncomfortable in the shorts.

You can’t begin a sentence with and since it’s a conjunction. You can’t say “a short” because you’ve already introduced them into the text. You’d say “the shorts” because we already know what shorts you’re talking about.

And I felt morevery uncomfortable in a shorts. And I felt very uncomfortable in shorts.

"shorts" is actually plural, even though it's just one piece of clothing!

And I felt more uncomfortable in a short clothes. And I felt more uncomfortable in short clothes.

And I felt more unless comfortable in a shorts. And I felt less comfortable in shorts.

Technically you shouldn't start sentences with "and" but it's ok for casual conversational English.

And I felt more uncomfortable in a short. I felt more uncomfortable in a short.
