That's something that's best to ask a doctor. It depends on the individual - there is no one recommendation everybody shoulddo.
Exercising to much
At least 20 minutes a day.
3 litres a day! or more if you are exercising.
After exercising and throughout exercising you should mainly drink water so your body doesn't get dehydrated.
of course, your supposed to drink water while your exercising
Of course. Yes!!
When you are exercising and after stretching
If you are overweight, or not strong, or do not have much energy, or you are in poor health, exercising can be annoying and uncomfortable.
Persons with breathing problems who want to start exercising should choose a low-intensity program.
Both pretty much go hand in hand. If your exercising why would you come home and eat junk food? If your dieting and not exercising you get no where.... to see results you should do both in a health way.
omg yes
You should drink water during and after exercising. It is easy to become dehydrated during exercise, fluids help to prevent dehydration.
