Missing Something?

One key factor many exercisers leave out is variety.  For best results,
you must use variety in your workouts to keep your body stimulated.  For
example, people often perform cardio with the same duration, intensity,
and exercise choice on a regular basis when they would be better off
variating their workouts.

Here's what to do:
-  Sometimes perform cardio sessions for 20 minutes "hard" and other times
go for 45 or 60 minutes "medium" intensity.  Don't make the big mistake of
using the same exercise choice every time.  One day you could do cycling,
and another day use the treadmill by walking at a 6 degree incline.

Remember, variety is the spice of life!

Exercise and Pregnancy

There has traditionally been controversy over the issue of exercise during
pregnancy.  Guidelines in the past may have been too strict in regards to
this issue.  Women who exercise regularly before pregnancy may be able to
continue exercising during their pregnancy, although certain restrictions
may be necessary.  Sedentary women who have not exercised before pregnancy
may be able to start lower intensity exercises such as walking, swimming,
low impact aerobics or water aerobics.

In general, exercise in the supine (laying down) position should be
avoided after the first trimester, since this may interfere with cardiac
output in the mother.  This may, in turn, decrease blood flow into the
placenta.

Resistance training may be continued at levels prior to pregnancy, and
non-weight bearing exercises such as swimming and cycling minimize the
risk of injury.
There are certain conditions that may be considered contraindications to
exercise during pregnancy such as:

Pregnancy-induced hypertension.
Preterm rupture of membranes.
Preterm labor.
Incompetent cervix.
Persistent second or third trimester bleeding.
Intrauterine growth retardation.

In conclusion, exercise may be enjoyed during pregnancy, especially in
women who exercise regularly before pregnancy.  In all cases, consultation
with an obstetrician prior to beginning an exercise program is advisable.
