Strength Training Terminology: Your Beginner's Glossary

Here are the key terms you need to know to confidently navigate your strength training journey:

Sets
A set is a group of repetitions (reps) performed consecutively in an exercise. For example, doing 3 sets of squats means you will perform a group of squats, rest, repeat again for a total of 3 groups.
Reps (Repetitions)
Reps, short for repetitions, refer to the number of times you perform an exercise in a single set. For instance, if your workout plan says "3 sets of 10 reps of bicep curls," you will perform 10 bicep curls in a row, rest, and repeat this two more times.
RM (Repetition Maximum)
RM stands for Repetition Maximum. It indicates the maximum weight you can lift for a specific number of repetitions with good form.
  • 1RM (One Rep Max): The maximum weight you can lift for only ONE repetition of an exercise. Often used to gauge maximal strength.
  • 10RM (Ten Rep Max): The heaviest weight you can lift while maintaining good form for 10 repetitions. Used to prescribe weight for hypertrophy training.

Understanding your RM helps you choose the appropriate weight for your workouts, ensuring you are challenging yourself effectively.

Intensity
Intensity in strength training refers to the effort level or how challenging a workout is. It's often related to the weight you lift in relation to your 1RM, or your Rate of Perceived Exertion (RPE).
  • High Intensity: Lifting heavier weights, closer to your 1RM, or working at a higher RPE. Typically used for strength training.
  • Moderate Intensity: Lifting moderate weights, around 65-85% of your 1RM, or working at a moderate RPE. Common for hypertrophy training.
  • Low Intensity: Lifting lighter weights, further from your 1RM, or working at a lower RPE. Often used for warm-ups, cool-downs, or active recovery.
Volume
Volume in strength training refers to the total amount of work you perform. It's often calculated as Sets x Reps x Weight. Volume is a key factor in driving muscle hypertrophy. Increasing volume over time is a form of progressive overload.
Tempo
Tempo describes the speed at which you perform each phase of a repetition. It's often expressed with numbers representing the duration in seconds for each phase:
  • Eccentric (Lowering) Phase: The muscle lengthening phase (e.g., lowering the weight during a squat).
  • Isometric (Pause/Hold) Phase: Holding the weight still at a specific point in the movement.
  • Concentric (Lifting) Phase: The muscle shortening phase (e.g., pushing the weight up during a squat).

For example, a tempo of "3-1-1-0" means: 3 seconds lowering, 1 second pause at the bottom, 1 second lifting, and 0 seconds rest at the top before the next rep.

Rest Period
Rest period is the time you take to recover between sets of an exercise. Rest periods vary depending on your training goals:
  • Longer Rest Periods (2-5 minutes): Used for strength training to allow for near-complete recovery and maximal strength output in subsequent sets.
  • Moderate Rest Periods (60-90 seconds): Common for hypertrophy training to balance recovery with maintaining muscle fatigue and metabolic stress.
  • Shorter Rest Periods (30-60 seconds or less): Used for muscular endurance training or circuit training to increase cardiovascular demand and metabolic stress.
Progressive Overload
Progressive overload is the principle of gradually increasing the demands on your body over time to continually stimulate muscle growth and strength gains. This can be achieved by:
  • Increasing Weight: Lifting heavier weights over time.
  • Increasing Reps: Performing more repetitions with the same weight.
  • Increasing Sets: Adding more sets to your workout.
  • Decreasing Rest Periods: Reducing rest time between sets (while maintaining performance).
  • Improving Exercise Technique: Perfecting form to ensure muscles are working optimally.
  • Trying More Challenging Variations: Progressing to harder exercise variations (e.g., from bodyweight squats to squats with dumbbells).

Progressive overload is ESSENTIAL for long-term progress in strength training and muscle hypertrophy.

Compound Exercise
A compound exercise is a multi-joint movement that works multiple muscle groups simultaneously. Examples include:
  • Squats
  • Deadlifts
  • Bench Press
  • Overhead Press
  • Rows

Compound exercises are highly efficient for building overall strength and muscle mass as they engage large muscle groups and allow you to lift heavier weights. They are often prioritized in strength training programs and form the foundation of effective hypertrophy routines.

Isolation Exercise
An isolation exercise is a single-joint movement that targets a specific muscle group. Examples include:
  • Bicep Curls
  • Triceps Extensions
  • Leg Extensions
  • Hamstring Curls
  • Calf Raises
  • Adduction Machine

Isolation exercises are useful for focusing on specific muscle development, addressing muscle imbalances, and "sculpting" individual muscle groups. They are often incorporated into hypertrophy training programs to further stimulate muscle growth after compound exercises.
