1. MUSCULAR STRENGTH AND ENDURANCE
If it weren't for the fact that the TV set and the refrigerator are so far apart, some of us wouldn't get any exercise at all.  ~Joey Adams

2. DEFINITIONS
Muscular Strength: The amount of force that a muscle can produce in one single contraction. (Heavy weight and few reps)
Muscular Endurance: The amount of force that a muscle can produce over an extended period of time. (Light weight and many reps)

3. BENEFITS OF MUSCULAR TRAINING
Reduce lower back problems
Look better
Increased performance
Reduced bone and muscle loss
Helps with weight control

4. WORKOUT DIFFERENCES
STRENGTH = Heavy weight (>80% 1RM) and few reps (3-5)
ENDURANCE = Moderate weight (30-50% 1RM) and many reps (12-20)
1 Repetition Max: The highest amount of weight that a person can lift for 1 repetition (1 Rep = Failure)
10 Repetition Max: The highest amount of weight that a person can lift for 10 repetitions (10 Reps = Failure)

5. TYPES OF CONTRACTIONS
Concentric: (Shortening)- One end is stationary while other end pulls bone
Eccentric: (Lengthening)- Controlled release of concentric contraction
Isometric: (Fixed)- Pushing against a fixed object

6. Each person is born with a percentage of each type of muscle.
TYPES OF MUSCLE FIBER
Fast-twitch (Type I): Used for muscle strength type of activities
Slow-twitch (Type II): Used for muscle strength endurance type of activities
Intermediate (Type Ia): Mix between types I & II
Each person is born with a percentage of each type of muscle.

7. WOMEN AND STRENGTH TRAINING
Women have same kind of muscles
Women have 1/3 less muscle fibers
Women do not produce as much testosterone
