EXECISE GUIDELINES
Building Muscle and Gaining Weight
Unlike aerobic exercise, which emphasizes endurance training, anaerobic exercise focuses on
strength training. A gradual weight gain can occur while building the size and strength of muscles.
While developing muscle mass, your body adapts to the stress placed upon it. You can modify your
diet to include foods such as meat, fish and vegetables. These foods help muscles recover and
replenish important nutrients after a strenuous workout.
Muscle Strength and Endurance
To achieve the greatest benefit from exercise, it is important to develop an exercise program that
allows you to work all of the major muscle groups equally.
To increase muscle strength, follow this principle:
Increasing resistance and maintaining the number of repetitions of an exercise results in increased
muscle strength.
To tone your body, follow this principle: Decreasing resistance plus increasing the number of
repetitions of an exercise results in increased body tone.
Once you feel comfortable with an exercise, you can change the resistance, the number of
repetitions, or the speed at which you do the exercise. It is not necessary to change all three
variables. For example, let’s say that you are training at 50 lbs and performing the exercise 10 times
in 3 minutes. When this becomes too easy, you may decide to move up lifting 60 lbs for the same
number of repetitions in the same amount of time. Lifting more weights fewer times most often
develops muscle strength. To gain both muscle strength and endurance, it is recommended that you
perform each exercise 15 to 20 reps per set.
Training Intensity
How hard you begin to train depends on your overall level of fitness. The soreness you experienced
can be lessened by decreasing the load you place on your muscles and by performing fewer sets. To
avoid injury, you should gradually work into an exercise program and set the load to your individual
fitness level. The load should increase as your fitness level increases.
Muscle soreness is common, especially when you first start exercising. If you are painfully sore for a
long time, it may be time to change your program. Eventually, your muscle system will become
accustomed to the stress and strain placed on it.

Beginning a Strength Building Program
Warming Up
To begin strength training, it is important to stretch and perform light exercise for 5 to 10 minutes.
This helps prepare the body for more strenuous exercise by increasing circulation, raising your body
temperature and developing more oxygen to your muscles.
Workout
For each workout, keep in mind that muscle soreness that lasts for a long period in not desirable and
may mean that injury has occurred.
Cool Down
At the end of each workout, perform slow stretching exercises for 5 to 10 minutes. Ease into each
stretch only going as far as you can. This stage allows your muscles to wind down after training.
To provide a total workout program it is also recommended that 2 to 3 days of aerobic exercise be
performed in addition to the strength training.
Drinking Water
For the body to function properly, it must be properly hydrated. If you are exercising, you should
increase your fluid intake. The reason for this is that the water you take in will leave your system
through the sweating mechanism that cools your body during exercise. The water you lose through
exercise must be replaced so that the muscles can recover properly.
Rest Day
Although you may not feel like doing it, taking a rest day at least once a week is important because it
gives your body a chance to heal it self. Continuously working your muscle will result in over training
which will not benefit you in the long run.
