  • TEF (Thermic Effect of Food): Grasp the energy spent to break down consumed food.
  • NEAT (Non-Exercise Activity Thermogenesis): Understand energy expenditure in daily non-exercise activities.
  • EAT (Exercise Activity Thermogenesis): Delve into energy burned through formal exercise.
  • TDEE (Total Daily Energy Expenditure): Comprehend the sum of RMR, TEF, NEAT, and EAT.
  • Reverse Diet: Ascend from a cut to maintenance by gradually increasing calorie intake.
  • Body Recomposition: Redefine weight composition with muscle gain and fat loss.
  • Cutting Phase: Strategically lower calories and increase activity to foster fat loss.
  • Bulking Phase: Elevate calories and workout intensity to foster muscle growth.
  • Mini Cut: Accelerate fat loss with a brief calorie reduction.
  • Diet Break: Revert to maintenance calories for a temporary respite from cutting.
  • Refeed Days: Pause calorie cutting for rejuvenation.
  • Fat Oxidation: Witness fat used as energy in the body.
  • Muscle Protein Synthesis: Grasp the process of muscle growth and repair.
  • Muscle Protein Balance: Attain equilibrium between synthesis and breakdown.
  • Macro: Embrace essential nutrients—fat, protein, carbohydrates—that fuel survival.
  • Glycogen: Uncover the storage form of carbohydrates in your body.
  • Amino Acid: Discover the building blocks of protein.
  • Net Carbs: Grasp carbohydrate content by subtracting fiber from total carbs.


Embark on your exercise journey armed with the language of movement:

  • Anaerobic: Engage in oxygen-independent glucose breakdown.
  • Aerobic: Embrace oxygen-supported glucose or fatty acid breakdown.
  • Lactate Threshold: Identify the point where lactate accumulates faster than it’s cleared.
  • VO2 Max: Push your oxygen utilization capacity to the limit.
  • Hypertrophy: Foster muscle growth.
  • Strength: Harness force-producing capabilities.
  • Reps: Execute one complete movement cycle.
  • Sets: Group repetitions before resting.
  • RPE (Rate of Perceived Exertion): Gauge personal intensity.
  • RIR (Reps in Reserve): Measure remaining reps before muscle failure.
  • Failure: Reach the point of inability to complete another repetition.
  • 1 RM (1 Repetition Max): Achieve maximum effort for one rep.
  • PB or PR (Personal Best/Record): Celebrate your best achievement.
  • Microcycle: Traverse one week of training.
  • Mesocycle: Experience 4-12 weeks of training before adjusting microcycles.
  • Macrocycle: Embrace an annual season of training, combining all mesocycles.
  • Deload: Indulge in a rest period with reduced intensity or volume.
  • Volume: Multiply reps, sets, and weights to uncover total work.
  • ROM (Range of Motion): Embrace the extent of movement.
  • TUT (Time Under Tension): Grasp the duration muscles are under load.
  • Tempo: Acknowledge movement speed during exercise.
  • Super Sets: Seamlessly transition between two movements.
  • AMRAP (As Many Reps/Rounds as Possible): Discover your potential within a time frame.
  • Progressive Overload: Gradually amplify training volume.
  • Eccentric: Experience muscle lengthening under tension.
  • Concentric: Feel muscle shortening under tension.
  • Isometric: Encounter muscles under constant tension.
  • Negatives: Strengthen the eccentric phase to enhance muscle and strength.
  • Isolation: Target single muscles via single-joint exercises.
  • Compound: Engage multiple muscles and joints in a movement.
  • Unilateral: Focus on one side at a time.
  • Bilateral: Activate both sides simultaneously.
  • Isolateral: Employ both sides independently, each with its own resistance.
  • Supinated: Orient palms upward.
  • Pronated: Position palms downward.
  • Neutral: Adopt a thumbs-up grip.
