I think Greg needs to start small than go bigger on the excersise .
He shouldn't rush on the process and he should be careful.Take everything slow.
He should work hard but not to the point where he gets hurt again or more.
Remind him to stretch before he does
Excersising.
He should run shorter distances and than later increase the number of miles or laps he is running .
I hope I helped I am not really a athletic person though
Since someone would be performing wind sprint activities, it is guaranteed when performing any activity is to get better overtime so I would say to "work above your target heart rate"
The best answer for this question is option E "Employers should adhere to certain health and safety standards for the wellbeing of employees." Occupational Safety and Health Act (OSHA) is all about safety of a employers workers. OSHA mainly talks about hazards, training before using a machine or tool, make sure there is no safety hazards that can affect the workers health.
Hope this helps!
