"With Oxygen" or cardiovascular exercise (cardio) that elevates heart rate in order to provide oxygen to the body as the source of energy for the activity.

The primary muscle used during a lift. It is contracted during the positive part of the movement, and it is elongated during the negative part of the movement.

"Without Oxygen" or exercise performed in short, highly intense bouts that do not require extra oxygen to the body. This system uses stored glucose in the muscles for energy.

The opposite muscle of the primary mover. It experiences a stretch during the positive part of the movement and is contracted during the negative part of the movement.

The rate at which an individual body uses energy (burns calories) at total rest. Represented as a full rested day of burned calories.

The lifting portion of any repetition in which the targeted muscle is being contracted/shortened by the movement.

A Series of sets in which the weight is decreased between each set. The weight should drop approximately 5-15% of the original weight for at least 10 sets. Between each set, only 5-20 seconds should taken as a rest. Ideally, each set will consist of 4-8 reps; if 10+ reps are easily completed, either the drop set is complete, but more likely too much rest time was taken and/or too much weight was removed. The goal of a drop set is to perform many sets near and at the point of failure. This will help achieve both maximal strength as well as strength endurance.

The lowering portion of any repetition in which the targeted muscle is being stretched/elongated by the movement.

The point in a rep where concentric movement is physically impossible and isometric holding is temporary.

The highest beats per minute (BPM) that is safe to push a heart rate to. Found by subtracting ones age from 220.

The increase and growth of muscle cells. Hypertrophy refers to an increase in muscular size achieved through exercise.

Any type of muscular stimulation in which the muscle is neither being lifted, nor lower. The muscle is neither being contacted nor stretched, but rather flexed in a fixed position usually bearing weight.

A style of weight lifting in which the rep is only worked at half the range, specifically the half that stretches the muscle the most.

The maximum amount of weight that can be lifted with proper form exactly one time.

The potential limit to which a joint or joints can bend to perform any given exercise. Full ROM = the largest possible path to move the weight.

The self reported feeling of effort given on any exercise. Expressed as a percent of maximum effort.

Complete movement of weight consisting of an eccentric phase, isometric point, and a concentric phase.

A consecutive series of repetitions.

Usually a group of two sets of different workouts done consecutively in which the second exercise targets different, and often antagonistic muscle/muscle groups

A muscle used to support and aid in the movement of a lift, but not the primary muscle responsible for the movement.

The idea BPM of an individual to efficiently maximize calories burned. Found by multiplying HRM with 85% or 0.85x(-220-age)
