Glossary

• Lifestyle Activities

  Lifestyle activities or lifestyle exercises pertain to physically active tasks rather than sedentary ones. For instance, choosing the stairs instead of the elevator is a lifestyle activity that will help boost your cardiovascular function and overall health.

• Lean Mass

  This is synonymous with lean body mass, which is your body’s total mass without the fat mass. When computing for one’s lean mass, the muscle mass, organs, and skin are included.

• Lean Bulk

  The goal of lean bulking is to maximise hypertrophy or muscle growth while keeping fat gain to a minimum. To achieve this, an individual typically adds five to 10 percent of his caloric intake to his daily meals and snacks.

• Lean Body Mass

  This refers to your body’s total mass less the fat mass. Your lean body mass includes your muscle mass, body water, bones, skin, and organs. It is also called lean mass.

• LATT

  This acronym stands for “lactic acid threshold training.” The goal of this type of training is to crank out intense reps until you reach your lactic acid or anaerobic threshold.

• Lagging Body Part

  A lagging body part simply means a body part that hasn’t progressed as much as other body parts or muscle groups. For instance, if your calves are underdeveloped, they’re your lagging body parts.

• Lactic Threshold

  Also known as the anaerobic threshold, this is the point where intense exercise results in more lactic acid accumulation than disposal. Lifters typically experience extreme discomfort during a lactic threshold.

• Lactic Acid

  Lactic acid is the byproduct of glycolysis, the production of energy during intense anaerobic or strength training. If you feel an intense burning sensation during your training session, it’s most likely due to a lactic acid buildup.

• Knee-Buckler

  This is an intense and heavy squat which can make your knees buckle. If a person is not used to this compound movement, it can make his knees wobble.

• Killing It

  You’re killing it at the gym when you are conquering your lifts and establishing PRs with reckless abandon; when you’re on a roll and breezing through your exercise program.

• Ketosis

  Ketosis is a state where your body doesn’t have enough carbs to burn for energy. Instead, your body uses fats as a fuel source. When you reach ketosis, you have ample amounts of ketones for energy. In the long run, you’ll also lower your caloric intake and increase fat loss.

• Karvonen Formula

  This is a way of measuring one’s overall fitness level by computing the target heart rate. To do this, you deduct your resting heart rate from your maximum heart rate. You then multiply this by the intensity (in %). Finally, you add this product to the resting heart rate.
