A bouncing movement. Movement due to momentum rather than muscular control.
Ballistic stretching involves "throwing" a body part in order to
stretch a joint beyond the range of motion attainable through controlled muscular
contraction such as when "bouncing" at the bottom of toe-touches.
It is an effective technique for causing injury to connective tissue, which
can reduce flexibility rather than enhance it.
A straight or curved bar typically five to seven feet in length designed to
have weights placed on the ends. A standard seven-foot olympic (takes plates
with 2" holes) barbell weighs either 44 pounds (20 kilograms) or 45 pounds,
not including collars.
Basal Metabolic Rate
The rate at which the body burns calories while awake but at rest (usually
measured in calories per day).
A piece of gym equipment with a horizontal or mostly horizontal top surface
designed to be sat upon or lain upon while performing an exercise. Benches
may be flat, inclined (angled so that an exerciser lying on the bench would
have his head higher than his hips), or declined (angled so that an exerciser
lying on the bench would have his head lower than his hips).
A common exercise for the chest and triceps. View
Bent Over Row
An exercise for the back, lats and biceps. View
A beta-agonist or beta adrenoceptor agonist is a drug or chemical that partially
mimics the effects of epinephrine, primarily targeting the beta adrenoceptors
which accelerate heart rate and increase blood pressure (beta-1), dilate bronchial
passages (beta-2), and release fatty acids from fat cells into the blood stream
(all beta receptors). The most commonly encountered beta agonists are asthma
drugs such as ephedrine and albuterol which target the beta-2 receptor.
The familiar "make a muscle" muscle that flexes the elbow joint.
Additionally, the biceps supinates the forearm and helps raise the upper arm
at the shoulder.
The large, two-headed muscle on the back of the thigh. Contracting this muscle
flexes the knee and also extends the hip (only one head of the muscle originates
above the hip joint and contributes to this movement).
Exercises targeting this muscle
BEI. The resistance of a path through the body (typically measured
between the feet and/or hands), most often used to estimate bodyfat percentages
because fat conducts electricity more poorly than muscle.
The actual value of a food upon digestion which can differ greatly then the
value assigned to it outside the body.

Lifting heavy objects that don't need to be moved in an effort to
increase muscle size, definition and symmetry.
Potential energy! Tissue comprised of fat cells that store energy. Body fat
is generally expressed as a percentage of total body weight or total body
Body Mass Index
BMI. Yet another way of approximating body composition for use in
large-scale medical studies and for health reports to refer to in the popular
press. This particular measure is calculated by dividing your mass in kilograms
by the square of your height in meters. While such simplistic measures are
useful for large statistical samples of the general population, their value
is highly limited for individuals, particularly athletes who can be very healthy
and have low bodyfat percentages despite having a higher-than-recommended
a web-based BMI calculator, bodyfat estimator, and other tools may be found

A variation on the squat performed with a bench, box, or other solid object
under the lifter that stops the decent at the bottom. This can cause excessive
compression of the spine and possibly lead to injury.
Hmmm... good question, I'll find out.
Branched Chain Amino
BCAA's. The amino acids L-leucine, L-isoleucine, and L-valine, so
named because of their branched structure. They are a major constituent of
muscle tissue and are preferentially consumed during intense exertion or dieting.
A type of fat cell with a greatly increased density of mitochondria and a
much greater blood supply than ordinary "white" fat. Besides being
able to store fat, brown fat cells can convert calories directly into heat
through a process known as non-shivering thermogenesis. Brown fat is used
by mammals to maintain body temperature and to expend excess calories that
are consumed but not stored as fat.
To gain size and mass, preferably (but not always) mostly or entirely muscle
and other lean tissue.
A weight plate (almost always olympic) with a rubber outer rim to reduce damage
to the floor (and the plate) in case it is dropped. These are most commonly
used in olympic lifting where very heavy weights are lifted overhead.
