Metabolism – The sum of all physiological processes in which matter is produced, maintained, and destroyed. The ability to burn and utilize energy (calories) is a factor of metabolism.
Calorie Deficit – The difference between the amount of calories you take in and the amount of calories you burn. If you create a daily deficit of 500 calories, you are on track to lose one pound of body fat per week.
Body Mass Index – A comparison of weight to height used to estimate body fatness. It does not, however, distinguish between fat and fat free mass (muscle). Thus, someone with lots of muscle may be falsely represented as ‘overweight’ or ‘obese’.
Basal or Resting Metabolic Rate – The amount of energy you expend just functioning from day-to-day. This number does not reflect any type of physical activity whatsoever. It is generally represented in calories.
Strength Training – Using an external load while isolating different areas of the body, to evoke a muscle response and adaptation over time.
Interval Training – Strength and conditioning using intervals of time rather than a set number of repetitions. A great way to mix in cardio with your strength training!
Repetitions – A rep is a single isolated movement from start to finish. Generally, any given number of repetitions forms a set.
Compound Set – Performing two exercises within the same muscle group with little or no rest in between.
Superset – Performing two exercises of opposing muscle groups with little or no rest in between.
