Training Suggestions

Before you workout

Prior to starting a training program, get a complete physical exam to make sure your physician
agrees that you are ready. Always warm-up your muscles before a workout. A 5 - 10 minute
cardio warm-up followed by slow stretching (no bouncing) is recommended. Continue with a
lighter set (50% of normal of intended exercises. Proper breathing is very important. Exhale
during muscle exertion, and inhale while returning to the start position. Start your program
conservatively. Choose weights you can easily lift in the first weeks. Always
perform the full range of motion unless you have an injury, then consult a
professional trainer. Your Cybex dealer can help you find one. Know the terms? A “repetition”
(rep) is defined as one complete movement through an exercise, returning to the start position.
A “set” is a continuous series of reps usually between 6 - 15.

During your workout

The number of reps. you perform in a set depends on your goal. To build muscle and strength,
do fewer reps (6 - 8) with heavier weight. To firm your muscles and build endurance, do more
reps. (12 - 15) with lighter weight. Never “cheat” by shortening the range of motion, bouncing
the weight, or shifting your posture. This may allow you to lift more weight, but it is dangerous
and less effective. Catch your breath between sets, then continue. When “circuit training”
move briskly to the next exercise; when doing multiple sets on one exercise, rest 45 - 90
seconds before the next set. Work up to three sets per exercise. When you can perform the
desired reps and sets for any exercise, increase the weight by a half or full plate.

Designing your workout

Circuit training is a good way to start. This involves doing one set per exercise, then moving to
the next exercise, pausing only briefly between them (to keep your heart and breath rate up)
until completing a balanced “circuit” of 8 - 10 exercises for your entire body. Then repeat the
circuit. After several weeks, you can move into multiple sets (3 in a row) per exercise if you
choose. For both of these, exercise the complete body every other day, up to three times a
week Note: A full day’s rest, plus proper nutrition and hydration are required for
optimum muscle-building or toning. Alternatively, work out half your body one day (e.g., the
upper body) and the other half the following day (e.g. the lower body). To reduce muscle
soreness, end each series of sets for a given muscle with a set of increased reps and lighter
weights. At the end of your workout, cool down in a similar way to your warm-up.

Abduction - movement away from the mid-line of the body.

Acceleration - the rate at which an object’s velocity changes with time; that is the change of

velocity divided by the time interval.

Accuracy - freedom from error. Degree of conformity of a measure to a standard or a true
value.

Action Line - the direction of pull created by the fibers or tendons of the muscle at the point of
application.

Active Insufficiency - a two joint muscle loses the ability to cross-bridge (generate force) due
to full shortening over its greatest anatomical length and tension created in an opposing muscle
(antagonist).

Active Range of Motion - the degree of motion that occurs between two adjacent segments
through voluntary contraction of the agonist.

Active Stabilization - provided by an internal force. Static stabilization is provided through an
isometric contraction where dynamic stabilization is a series of motions. Dynamic stabilizers
maintain the relative positions of the segments, preventing undesirable or unnecessary motions
due to external forces as well as artifacts of internal forces. May also refer to the
concentric/eccentric contractions of a muscle acting in a force couple to produce motion while
maintaining a relatively fixed axis of rotation.

Adipose tissue - fat tissue.

Adduction - movement towards the mid-line of the body.

Agonist - (prime mover) the muscle most involved in producing a movement.

Aerobic - utilizing oxygen.

Aerobic Endurance - the ability to persist in physical activities that rely heavily upon oxygen

for energy production.

Anabolic - pertaining to the synthesis of complex substances from simpler substances, especially
to the synthesis of body proteins from amino acids.

Anaerobic - without oxygen.

Anaerobic Endurance - the ability to persist in physical activities of short duration that require

high rates of energy expenditure. These high rates of energy expenditure cannot be met solely
by aerobic metabolism.

Cardiovascular - pertaining to the heart and blood vessels.

Cartilage - there are several types. Hyaline cartilage is a relatively thin covering on the ends of

many bones. It forms a smooth, resilient, low friction surface for the movement of one bone
on another. Wedges of cartilage (fibrocartilage) called menisci, disks and labrums are to
increase stability, provide shock absorption, and to facilitate motion in some joints.

Center of Gravity - the center of a body’s mass. In the human body, it is the point which all
parts are in balance with one another. The COG may be within the body, altered by the position
of the body even to the point of being outside the body (pike position), or altered by the
addiction of load to specific body areas.

Circumduction - a circular movement permitted at ball and socket, condylar and saddle joints.
Consists of flexion, abduction, extension and adduction in sequence.

Circuit Training - a conditioning program consisting of a number of exercises performed at
“stations”. Usually, a given exercise is performed at a station within a specified time; then the
athlete moves to the next station, with its own particular exercise and specified time, then to the
next station, and so on.

Closed Chain Kinetic Exercise - a series of rigid links interconnected by a series of
pincentered joints. These are constructed so that motion at one joint will produce motion at all
the joints in the system. Produces greater mechanical efficiency at the risk of increased joint
loading. Leg press, bench press.

at a joint. There can be more than one prime mover for a particular motion and a specific
muscle can be a prime mover for more than one motion at a joint.

Progressive Resistance - overloading a muscle or muscle group consistently throughout the
duration of a weight-resistance program.

Pronation - a triplanar motion at the subtalar joint consisting of abduction, depression and
eversion, resulting in lowering of the longitudinal arch of the foot. Position of the forearm with
the palm facing down.

Protein - a basic foodstuff containing amino acids.

Proximal - towards the attached end of the limb or origin.

Range of Motion - the amount of motion available to a joint within the anatomical limits of the

joint structure. Can be classified as Passive (movement produced via a force outside the limb),
Active (movement produced by muscles within the limb) or Resisted (movement challenged

under additional load). The amount of resistance will affect the range of motion with direct
proportion.

Reciprocal Inhibition - contraction of agonist causes relaxation of antagonist.

Reliability - the extent to which an experiment, test or measuring procedure yields the same

results on repeated trials. Also known as reproducibility or repeatability.

Repetition Maximum (RM) - the maximum load that a muscle or muscle group can lift in a
given number of repetitions before fatiguing. For example, an eight-RM load is the maximum
load that can be lifted eight times.

Repositioners - muscles that lift the extremity and move it to a new location allowing the
prime movers to again accept load or propel.

Response - a sudden temporary adjustment in physiological function brought on by a single
exposure to exercise, e.g., the rise in heart rate associated with an exercise bout.

Rotary Motion - (radial or angular) the movement of an object around a fixed axis in a curved
path.

S.A.I.D. Principle - Specific Adaptation to Imposed Demand. A muscle will gain strength in
the specific ranges of motion and speeds in which it is trained.

Sagittal Plane - Imaginary line that divides the body, or any of its parts, into right and left
sections.

Scoliosis - a lateral curvature of the vertebral column, usually in the thoracic area.

Secondary Joint - hinge joints that have a singular function (elbow/knee). Muscles are

situated on either side of these joints in virtual, if not real, pairings.

Set - in an interval training program, a group of work and relief intervals. In weight lifting, the
number of repetitions performed consecutively without resting.

Shear - two parallel forces applied in opposite directions that are not in line with each other

constitute a shearing load or stress. The site of muscular attachment is the axis around which
the forces of shear develop. This becomes the “force axis” as opposed to the anatomical axis.

Shunt Muscle - directs the greater part of its contractile force along the bone it is moving
(creating greater force towards compression/stabilization). The brachioradialis is a shunt
during an arm curl.

Skeletal Muscle - muscle controlling skeletal movement that is normally under voluntary
control.

Skewing - the result of a vector shift through a limb or system.

Sliding Filament Theory - a muscle shortens or lengthens because the thick and thin

myofibrils slide past one another without the filaments changing length.

Slow-twitch Fibers - skeletal muscle fibers characterized by relatively slow contraction times
and great capacity for the aerobic production of adenosine triphosphate.

Sprain - the permanent deformation of the structure due to excessive or prolonged
stress/strain.

Spurt Muscle - directs the greater part of its force across the bone it is moving rather than
along it (creating greater effort towards motion). The biceps is a spurt during an arm curl.

Stabilizer - a muscle that steadies or supports a joint in order that another active muscle may
have a firm base upon which to pull.

Static contraction - a muscular contraction that does not involve changes in the angle of the
joint(s) involved.

Steady state - that state of physiological stability wherein the energy demands of the body
can be met relatively easily for a prolonged period of time.

Strain - the deformation of the structure as the result of stress.

Strength - the ability to exert muscular force briefly.

Stress - the force created within a structure when placed under load.

Submaximal exercise - usually exercise at less than maximal intensity, but may also refer to

exercise of less than maximal duration.

Superior - a higher position upon or within the body.

Synergist - occurs during the action of two muscles, both of which have a common joint

action and each of which has a second action that is antagonistic or opposing to the other.
True synergy is simply the stabilization of one muscle to prevent any action in one of the joints
traversed by a multi-joint muscle.

Synovial Fluid - transparent, viscous lubricating fluid found in joint cavities, bursae and tendon
sheaths.

Tendons - cords of dense fibrous tissue that connect muscle to bone.

Tertiary Joint - a complex joint structure (wrist/ankle-subtalor), designed for finely controlled

movements.

Torque - the ability of a force to produce movement around an axis.

Training - a program of exercise designed to improve the skills and increase the energy

capacities of an athlete for a particular event.

Translatory Motion - (linear) the movement of an object in a straight line.

Unilateral - refers to only one side.

Validity - the extent to which a measurement or information is relevant or meaningful;

appropriate to the end in view and supported by objective truth.

Vector - an arrow which represents a force’s point of application, action line or direction
indicating pull or magnitude of force being exerted.

Vector Shift - the alteration of a load as it is transferred between the anchor points through a
segment’s kinematic chain.

Velocity - the rate at which an objects position changes with time; that is the total change in
position divided by the total change in time: V-d/t.

Weight - the weight of an object is the gravitational force exerted on it by the earth. W=mg,
where g = gravitational acceleration.

Work - W = Fd. The amount of work performed is equivalent to the force applied to an object
times the distance the object is moved.

See Chapter 6 for proper installation. Allow the appropriate operating space between
machines. It is the responsibility of the purchaser to determine the appropriate operating
space for customer safety and convenience. Do not crowd the exercise area.

Safety

Use extra caution when assembling and installing equipment, particularly when lifting or
moving heavy objects (such as installing weight stacks) and when using power tools.

Installation

Upon arrival, it is important that you thoroughly inspect all of the equipment for damage.

If you discover damage, point it out to the truck driver and request that the driver make a
record of the damage on the receiving report. Be sure to obtain a copy of the receiving report
for your files.

Apparent Damage - Any damage seen with a visual check must be noted on the freight bill
and signed by the carrier’s agent. Failure to do so will result in the carrier’s refusal to honor
your damage claim. The carrier will provide you with the required forms for filing such claims.

Concealed Damage - Damage not seen with a visual check upon receipt of a shipment but
noticed later must be reported to the carrier as soon as possible. Upon discovery of the dam­age, a written or phone request to the carrier
asking them to perform an inspection of the materials must be made within ten days of the
date of delivery. Keep all shipping containers and packing
materials - they will be needed as part of the inspection process. The carrier will provide you
with an inspection report and the necessary forms for filing a concealed damage claim.
Concealed damage is the carrier’s responsibility.

• Contact Cybex Technical Support if you received damaged equipment and

provide them with the information on the report regarding your damaged
equipment.

• Contact Cybex Inside Sales if you did not receive the appropriate

equipment and provide them with the information regarding your order.

You may call Cybex at 888-462-9239 (888-GO CYBEX) and specify if you are calling for a
