You are a nervous type and hence good relaxation is a must for you. You can take up yoga or some form of meditation for the same.
Deep breathing exercises are also advised as your weakness lies in the lungs. You quit from exercising if it is not interesting. Hence stick to those ones that are really stimulating for your nerves.
Each one of our body is
different from the other in the sense that
our eating habits, exercising schedules vary. If you are
out there looking for a way to cut some flab then you need
to understand the five element theory as well. If you are a
water sign then your exercises should be built around water,
if an airy sign then you need to face the wind, if a fiery
sign like an Aries then you need to get heated
up and if an earthy sign then you need
to connect to the earth. These are basic techniques
that help you to understand how exercising
shall be more beneficial for you...
