Myth #10 - You need to drink six to eight glasses of water a day.
In February 2004, after reviewing more than 400 studies, the National
Academy of Sciences’ Institute of Medicine concluded that men need
about 15 cups of fluid a day and women about 11. But
that includes fluids from all beverages, including the alcoholic and
caffeinated kinds, and the water in food. The vast
majority of Americans already get that much liquid in their everyday diets.
Water loss increases after exercise, but most people naturally feel thirsty
and drink more fluids without being prompted. However,
people over the age of 65 or children should pay special attention to
their fluid intake, since the sense of thirst isn’t as sharp. Strong
smelling, dark yellow urine indicates that you need to drink more. Finally, while any beverage counts toward your daily intake,
plain tap water does offer several advantages: It’s cheap, thirst quenching, and calorie-free.
Myth #9 - Lifting heavy weights add bulk.
Adults may or may not become “bulky” when lifting heavy weights. Women are told to lift weights with high repetitions to avoid
“bulk”. These both are determined by our genetics, not our
lifting routine. Women are less likely than men to add tremendous bulk when lifting
weights. High levels of testosterone are necessary for muscles to
add large amounts of bulk. The genetics of each individual
determine who can add bulk and who cannot.
This is perhaps the most common myth women fall for and it couldn’t be
farther from the truth. In fact, weight training is often the
easiest and quickest way for women to look leaner, more sculpted and
toned. You’d have to be taking steroids to achieve the bulked-up
look most body builders have, so don’t be afraid of weights. Incorporate strength training twice a week into your exercise program
because it will help protect you from injury, tone your muscles, help
prevent osteoporosis and burn excess body fat, even when you are resting.
Myth #8 - You burn more fat when you exercise at a low intensity for a long amount of time.
The most efficient way to burn fat is to combine intense training
in short spurts with a nutritious diet. For example, 30 minutes of
cycling in intervals, where you continuously vary your speed, intensity
and pace, burns more calories than a slow one-hour walk. And it
keeps burning them when you stop because your metabolism stays elevated
for a few hours after you exercise.
Myth #7 - You can lose weight by dieting.
More than 90% of all people who lose weight by dieting gain it back.
Change your eating habits and choose to eat more fruits and vegetables
and less fat. Dieting is temporary deprivation. Eating
healthy means developing a new mindset. The real trick to losing
weight is a lifelong pattern of moderate exercise, healthy diet, and 7-8
Myth #6 - The best time to exercise is early in the morning.
Not true. There is no one best time to exercise. The best time is
the time that appeals to you and fits into your schedule. Some
folks love to jump-start their day with a morning workout, while others
swear that exercising after the workday is over is a great way to
energize for the evening and eliminate stress.
Myth #5 - Pasta and bread are fattening.
Anything is fattening! Lettuce can be stored as fat! Any food or drink
which contains calories can be stored as body fat if it causes your
blood sugar level to exceed what the body needs at that time. Bread and
pasta area actually great sources of complex carbohydrates! The key is how
much you eat and when you eat it.
Myth #4 - if you stop an exercise program your muscle will turn to fat.
Fat cannot turn into muscle any more than a rock can turn into water.
They are two different components. When you stop working out, you lose
muscle tone and gain fat, but one doesn’t turn into the other.
Myth #3 - You’ll burn more calories jogging a mile than walking a mile.
Caloric expenditure is 62 calories
per 100 pounds body weight per mile traveled (walked or jogged).
For example, if you weigh 150 pounds, you expend 93 calories per
mile walked or jogged (62 x 1.5). Of course, if
you’re jogging, you’ll cover the distance in less time than if
you’re walking. Thus, you’ll burn more calories
in a given period of time if you’re jogging.
#2 - Stretching before exercise boosts performance and prevents injury,
and getting a massage afterward speeds recovery.
large reviews, published in 2004 and 2005, failed to support the notion
that stretching your muscles before exercise prevents injury or
post-exercise muscle soreness. Similarly, at least five clinical trials
now show that getting a massage after exercise doesn’t help restore
muscle strength and does little to soothe aching muscles.
The component that is most often left out of a fitness program is
stretching. If you are like most people, you probably
think that right after you are finished your last set, you should head
for the showers. However, you should really finish
off with some stretching, as it will increase the range of motion in
your muscles and joints, which will thus allow you to perform your
weightlifting exercises over a greater range of motion, as well as
target more muscle fibers throughout the lift.
Finally, when you finish off your workout
with some stretching, you reduce the severity of DOMS (delayed onset
muscle soreness), which you will most likely greatly appreciate the next
Fitness Myth #1 - You can lose fat from a specific part of your body by
doing an exercise for that part of your body. For
example, abdominal crunches will remove fat from your abdominal area.
You can’t spot reduce! You cannot control where fat
is removed from your body. The one thing everyone
wants is a flat stomach. No matter how many sit-ups you do it won’t be
flat if you have a layer of fat covering your muscles. Your time would
be much better spent doing some quality cardio sessions and making sure
you’re eating well, which would help you lose body fat than doing more sit-ups.
Many exercise devices are marketed to spot
reduce or spot tone a specific body part. The idea is
that by using their device you will be able to tone the inner thighs,
for example. This is simply not true. Muscles
utilize blood glucose, cellular energy stores, and blood fat for energy. Fat is not pulled from the area it is stored in to serve as
energy in its own “neighborhood”. Once blood
glucose levels are low, a hormonal reaction is triggered to metabolize
stored fat for conversion to glucose for energy. Fat
deposits are tapped in multiple places around the body, not adjacent to
the body part requiring the need for energy.
A properly structured strength and conditioning program will result in a
leaner body appearance (when combined with proper eating habits.) This is in part due to fat loss and muscle hypertrophy (size
increase). The amount of toning is, unfortunately,
bases on one’s genetic predisposition for muscle growth and fat
storage. We cannot, unfortunately, change how our
body is programmed to add muscle and store fat.
