When Are we Allowed to Change Tenses and Persons?

Question

For Example

The time that this activity is done for is between 20-60 minutes. Begininners should start at 20 minutes and increase their time by 5 minutes each week until 60 minutes is reached. Experienced people should just start at 60 minutes. It is not that beneficial to go over 60 minutes of contineous jogging because that puts our bodies over too much pressure and don’t have enough time to rebuild and adapt stress. A rare disease called rhabdo is caused if we push ourselves too much over the limit. (Read Article 5 for more detail) Since I have somewhat experience with jogging, I will start at 30 minutes each jogging session and build up my time by 5 minutes each week until I reach 60 minutes.

Answer 1

The time that this activity is done for is between 20-60 minutes.

 

Blech! Too wordy! How about, "This activity takes between 20 and 60 minutes to complete."

Begininners should start at 20 minutes and increase their time by 5 minutes each week until 60 minutes is reached. Experienced people should just start at 60 minutes.

 

The first word is misspelled. 

 

It is not that beneficial to go over 60 minutes of contineous jogging because that puts our bodies over too much pressure and don’t have enough time to rebuild and adapt stress.

"Contineous" is misspelled. Use "under" instead of "over." "Don't have enough time" is not in correct sequence with its subject. That's like saying, "because that don't have enough time." You could say, "under too much pressure. They need more time to rebuild..."

"Adapt stress" means that one is trying to adapt the stress itself. Try "adapt to stress," as the body is trying to adapt itself to stress.

 

A rare disease called rhabdo is caused if we push ourselves too much over the limit.

 

This is passive voice, which writers should generally avoid. Try, "Pushing oneself over the limit causes a rare disease called rhabdomyolysis."

 

(Read Article 5 for more detail) 

 

Missing period.

Since I have somewhat experience with jogging, I will start at 30 minutes each jogging session and build up my time by 5 minutes each week until I reach 60 minutes.

 

"Somewhat" is the wrong word here. You could say either "I have some experience" or "I am somewhat experienced." Most editors suggest avoiding single-digit numerals. Say "five minutes" instead of "5 minutes."

Answer 2

The activity takes about 20-60 minutes to get done.  Beginners should start by doing it for 20 minutes with 5 minutes increments per day for a total of 60 minutes.  The joggers must do this activity for 60 minutes at the advanced level.  It is advisable to follow the 60 minute routine as overdoing it can put irreversible stress and pressure on the skeletal structure and can eventually result in a condition called rhabdomyolysis ( Article 5 ).  Since I am a habitual jogger I will begin by doing the activity for 30 minutes and gradually increase it by 5 minutes till I reach my 60 minutes mark.
