Building abs and sculpting muscles
starts long before you ever hit the gym. Muscle growth requires a formula based
on drinking plenty of fluids and eating the right energy-rich foods along with
lifting weights. The right formula will fuel workouts, repair muscle tissue,
and help you sculpt your physique.
Nutrition
Game Plan
1. Fruit and vegetables are the
foundation of all healthy diets, providing fiber, vitamins, minerals, and
fluids. Vegetables contain small amounts of protein.
2. Low-fat dairy provides high-quality protein,
carbs, and essential vitamins such as vitamin D, potassium, and calcium. Sports
nutritionists Christine Rosenbloom, PhD, RD, and Nancy Clark, RD, recommend
chocolate milk as a good workout recovery beverage. If you are lactose
intolerant, you can try yogurt with active cultures.
3. Lean meat is a great source of protein, iron
for oxygen transport to muscles, and amino acids including leucine, which,
Rosenbloom says, is thought to be a trigger for muscle growth.
4. Dark-meat chicken, compared to
white meat, provides 25% more iron and three times the zinc for a healthy
immune system.
5. Eggs "contain all of the essential
amino acids," Rosenbloom says. One a day is fine according to the 2010
Dietary Guidelines, but don’t throw out the yolk. According to Rosenbloom,
"Half the protein is in the yolk along with other import nutrients like
lutein for eye health.”
6. Nuts -- unsalted and either raw or roasted
-- are a good source of protein. They also contain vitamins, antioxidants,
fiber, and healthy fats.
7. Beans and whole grains are quality
carbs that contain small amounts of protein for energy and muscle repair along
with fiber, vitamins, and antioxidants.
Timing
Is Everything
Timing is critical in muscle
development because you need carbs and protein to perform strength training and
protein and carbs for muscle recovery. The best plan is to eat a diet
containing both nutrients and small amounts of healthy fats throughout the day.
“Consuming a protein beverage like
chocolate milk within an hour after exercise will give muscle the building
blocks it needs when it is most receptive for repair” says Rosenbloom.
If you will be eating a meal within
1-2 hours after a strenuous workout, Rosenbloom says you don’t need a snack and
can wait for the meal to provide the recovery nutrition.
How
Much?
More than half your calories should
come from healthy carbs, Clark says. “Carbs supply fuel for energy and prevent
protein from being broken down and used as an energy source. So always fuel up
before working out.”
But be careful: It is a delicate
balance of eating enough calories to build muscle but not too many calories, which
can lead to gaining body fat.
Protein builds and repairs muscle
tissue in addition to performing other functions, like producing hormones and
immunity factors. The ADA suggests male endurance athletes get 1.2 grams of
protein per kilogram of body weight, whereas male body builders may need 1.6 to
1.7 grams of protein per kilogram of body weight.
“Two cups of milk contain about 20
grams of protein, which is the amount recommended to stimulate muscle protein
synthesis," Rosenbloom says.
But most people don’t eat by the
numbers. Clark advises her athletes to divide their food into four equally
sized meals and choose three out of these four options: fruit or vegetable,
grains, healthy fats, and calcium-rich or lean protein at each meal.
“The foundation of each meal is based
on healthy carbs, with additional protein like oatmeal with nuts and yogurt,
turkey and cheese sandwich with veggies, or spaghetti with meat sauce and a
salad. These are all great for body building,” says Clark, author of Nancy
Clark’s Sports Nutrition Guidebook.

Muscle-Building Results by Fatiguing Muscles
The only way to build bigger, more
defined muscles is with progressive resistance training -- gradually increasing
weights and endurance. Use a weight heavy enough to cause muscle fatigue after
9-12 repetitions. If you can easily do 13 repetitions with good form, you need
to increase the weight.
“It is the act of pushing the muscles
past the comfort zone that promotes muscle growth and more definition,"
Clark says.
Strength training results show up
quicker than aerobic exercise. “It’s encouraging to start seeing enhanced
definition fairly soon after working out at least twice a week for 30-45
minutes," Rosenbloom says.
The exact length of time it takes to
start seeing enhanced definition of your muscles also depends on your
percentage of body fat. An extra fat layer around your muscles will not let the
newly toned muscle show through without weight loss. Clark says gaining 2
pounds of muscle per month is a reasonable expectation.
Strength training is vital to building
muscles, but it is also an important part of any fitness program and should be
done 2 to 3 times per week for 20 to 30 minutes each time. “It is a great
investment in your future well-being because you need to use your muscles or
you will lose them," Clark says.
As we age, strength training helps
maintain muscle strength, prevent osteoporosis, and decrease muscle and joint
injuries.
Rosenbloom recommends going to a gym
where you can work with a trainer to understand how to properly perform muscle
building exercises to challenge but not injure your muscles.
