The Effects of Exercise on Our Health
1) As is known to all,exercise does bring a lot
of benefits to our health,2) First,it can greatly
strengthen our hearts,lungs,bones and muscles,
thereby changing our whole health for the
better,3) Besides,it can make our brains better
able to react to what is going on around us,4)
And best of all,it can help us breed optimism
about our tough life.
5) But all the above does not mean that we can
turn a blind eye to the negative effects exercise
brings about,6) If you are normally inactive and
then,contrary to your usual habit,start a
program of undue exercise,as a succession of
scientific studies reveals,there are more chances
that you have yourself injured,7) In addition,
the more exercise those on a fat-reducing diet
take,the more loss of iron they will suffer and
the worse their health will get,8) And
worst of all,continual as well as excessive
exercise can result in sudden death,
9) Therefore,a scientific approach must be
adopted to the problem of exercise,10) On the
one hand,our physical exercise must be based on
both progressiveness and regularity,11) On the
other,we must go in for physical exercise
according to local as well as health conditions of
our own,12) In sum,exercise can do us good or
harm,all depending on how we make use of it.
