Workouts and Learning English

You can also say "Working out" here.

The following sentences are written without a dictionary so that you might find it difficult to read.

"So that" = I am doing it this way for this specific purpose. Here, this would mean that you are intentionally writing without a dictionary to make it difficult to read, which isn't what you mean :)
"So" can mean the same as above but can also just mean, "with the result that" (not necessarily intentional).

Some examples:
I am writing you a note so that you remember to buy the eggs.
I lost my passport so I missed my flight (I unintentionally missed my flight because I lost my passport).
I lost my passport so that I missed my flight (I deliberately lost my passport because I wanted to miss my flight).

I was away frommissed English tpraining these daysctice recently because I am curious about the Japanese stock market.

It sounds more natural to say English practice here. Training usually refers to practice for a physical activity or training for work.

Missed also sounds better than "was away from" because the latter generally means you were away from a physical place (e.g I was away from school) rather than an activity.

Shared is okay, but discussed would sound better.
