A health club
(also known as a
fitness club,
fitness center,
and commonly
referred to as a
gym) is a place
which includes
exercise equipment
for the purpose of
physical exercise.
Most newer health
clubs offer group
exercise classes
that are conducted
by qualified fitness
instructors. Many
types of group
exercise classes
exist, but generally
these include
classes based on
aerobics, cycling
(spin cycle),
boxing, martial
arts, high intensity
training, yoga,
pilates and muscle
training. Health
clubs with swimming
pools often offer
aqua aerobics
classes.
