EXERCISE 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 23 kg (50 lb.) and performing the exercise 10 times in 3 minutes. When this becomes too easy, you may decide to move up to lifting 27 kg (60 lb.) 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, to keep in mind that muscle soreness that lasts for a long period is 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 is 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 itself. Continuously working your muscles will result in over- training, which will not benefit you in the long run. 

WARNING LABEL PLACEMENT
