Muscular Strength
Muscular Strength and Endurance
Muscular strength is the capacity of your body’s muscles to generate extreme amounts of force in a
short period of time utilizing anaerobic energy. Anaerobic energy provides short term bursts of energy
and does not require oxygen. Instead anaerobic energy comes from the burning of carbohydrates and
can be sustained for a few minutes, after which a short rest time is needed to replenish the system.
Anaerobic energy is used for everything from weight lifting and sprinting to the low impact sports of
tennis and golf. Anaerobic energy is also used within aerobic-centered workouts when additional spurts
of energy are needed.
Enhanced muscular strength often increases muscle and connective tissue size and density by enlarging
cells or building muscles. Apart from their aesthetic value, larger muscles and connective tissue are les
prone to injury and aid long term weight control. Because muscle tissue burns more calories than fat,
even while resting, someone with more muscle will use their stored fat energy on a daily basis.
Tips for Building Muscular Strength
Focus on your exercises. Concentrate on activities that work specific muscle groups and use a
program that splits the routine into specific muscles groups each day rather than a full body
workout. Lift weights slowly and focus on using the best technique rather than the most weight.
Your workout needs to be efficient first.
Control lactic acid. Anaerobic activity produces lactic acid build-up in muscle, which can lead to
muscle soreness and cramping. Doing some light cardio post workout and stretching before and
after workouts can help remove the lactic acid.
Gradual Progression is important. It is more important to get the proper technique first than
look to maximize the weight you can lift. Progression of the stress placed on a muscle is
important for continued gains in muscle strength. Averaging 3 sets of 6 – 8 repetitions is an
excellent way to gain muscle strength, just be sure to increase your weight when you can
perform more than 8 repetitions easily.
Warm-up. A warm-up set or light cardio activity can help prepare the body and mind for a more
intense workout without injury.
Rest. With more intense workouts, and more damage to the muscles as a result, one or two
days of recovery time is necessary. Allowing the muscle to recover fully will also help prevent
overtraining injuries.

Muscular Endurance
Muscle endurance is the measure of how well muscles can repeatedly generate force, and the amount
of time they can maintain activity. Muscular endurance is necessary for everyday activities, which
typically involve low impact movements. It is crucial for every fitness activity, from the mostly anaerobic
weight lifting repetitions to the intense aerobic activities like jogging. Muscular endurance combines
both aerobic and anaerobic energy and training for endurance not only involves repeatedly generating
force, but the speed of recovery in a muscle.
Tips for Building Muscular Endurance
Gradual Progression. Like muscular strength, muscle endurance is increased through overload.
Overworking the muscle with a lighter weight but more repetitions is the best way to train for
muscular endurance. Averaging 3 sets of 10 to 15 repetitions is an excellent way to build
endurance. Keep in mind that a spotter should still be necessary for the final 1 or 2 repetitions
to get the most benefit.
Recovery Time. Rest and recovery is necessary for your muscle, but decreasing the time
between sets is a way to force the muscle to have faster recovery rate. If more than 12
repetitions are being performed, less than a minute between sets is recommended.
