it seems like we're constantly hearing
different fitness advice exercise two to
three times a week for at least 30
minutes a day and don't forget cardio
but don't exercise too much or you'll
get hurt so how much exercise should you
be getting well actually not that much
since the human body is only built to
withstand walking a short distance
before lying or sitting down again in
fact a group of biologists from Stanford
found that walking more than five feet
at a time can cause joint pain fatigue
and even extreme hunger the study
concluded that the maximum effort the
human body can safely endure is reaching
for an item high on a shelf our bodies
simply aren't built to stand up and move
around so maybe those high intensity
spin classes and daily jobs aren't such
a good idea instead of walking up the
stairs every day try taking the elevator
whenever possible make sure to replenish
your body after exercising and next time
you're at the gym change up the routine
a bit and consider lying down on the
treadmill every once in a while you can
even use a fitness tracker to let you
know when you've been exerting too much
energy your body will appreciate it for
the onion
