How Many?

How many weight training exercises per muscle group should you perform? 

Well, it depends on your goals and fitness level.  If your experience with
weight training is less than 6 weeks or if your fitness goals include
general conditioning, then performing one exercise per bodypart is
sufficient.  However, if your goals include increased muscle mass, sports
training, or strength conditioning you may want to perform 2 to 4
exercises per muscle group.

Keep in mind that if you perform the same exercises day in and day out
your body will figure out what's going on and adapt to your routine.  This
means no progress for you.  Keep the body guessing by switching exercises
on a regular basis regardless if you are doing 1 or 4 exercises per muscle
group.

Hypothermia

Although spring time approaches, there is still enough winter left to be
aware of hypothermia.  Hypothermia refers to a lowering of core body
temperature, usually as a result of exposure.  Actually, many cases of
hypothermia occur at relatively mild temperatures.  The risk of
hypothermia increases with exposure to wind or moisture, which tend to
negate the insulating properties of clothing.

The early stages of hypothermia may simply resemble an extreme feeling of
cold.  As the body's temperature continues to drop, the shivering
mechanism may cease--a bad sign.  Further drops in temperature lead to
mental changes, and some victims exhibit the puzzling behavior of
paradoxically removing clothing.  Left untreated, hypothermia can lead to
fatal heart rhythm abnormalities.

In terms of treatment, it is critical to get the victim into dry, warm
clothes.  This, however, assumes he or she can still generate body heat,
which may not be possible in advanced hypothermia.  In this case, central
body warming needs to be accomplished by trained medical personnel.

The best defense against hypothermia is prevention.  Be sure to keep warm
and dry.  Carry extra layers of clothing.  Avoid cotton, as it loses its
insulating properties when wet.  Synthetic fibers such as fleece or
polypropylene, or natural fibers such as wool, can maintain warmth, even
when wet.  REMEMBER:  You can survive weeks without food, days without
water, but only a few hours with hypothermia.
