Inversion
– Moving sole of foot toward medial plane.
Intensity
- The relative degree of effort that you put into each
set of every exercise in a bodybuilding workout. The
more intensity you place on a working muscle, the more
quickly it will increase in hypertrophy. The most basic
methods of increasing intensity are to use heavier weights
in good form in each exercise, do more reps with a set
weight, or perform a consistent number of sets and reps
with a particular weight in a movement, but progressively
reducing the length of rest intervals between sets.
Isokinetic
Exercise - Isotonic exercise in which there
is ACCOMMODATING RESISTANCE. Also refers to constant
speed. Nautilus and Cybex are two types of isokinetic
machines, where machine varies amount of resistance
being lifted to match force curve developed by the muscle.
Isometric
Exercise - Muscular contraction where muscle
maintains a constant length and joints do not move.
These exercises are usually performed against a wall
or other immovable object.
Isolation
Exercise - In contrast to a basic exercise,
an isolation movement stresses a single muscle group
(or sometimes just part of a single muscle) in relative
isolation from the remainder of the body. Isolation
exercises are good for shaping and defining various
muscle groups. For your thighs, squats would be a typical
basic movement, while leg extensions would be the equivalent
isolation exercise.
Isotonic
Exercise - Muscular action in which there is
a change in length of muscle and weight) keeping tension
constant. Lifting free weights is a classic isotonic
exercise.
