Training
Principles and methods for building strength and muscle.
Progressive Overload
Gradually increasing training demands to keep making gains.
Hypertrophy
The growth of muscle size through training and nutrition.
Strength
The maximum force a muscle or group can produce.
One-Rep Max (1RM)
The heaviest weight you can lift for a single repetition.
RPE (Rate of Perceived Exertion)
A 1–10 scale for how hard a set felt, used to gauge intensity.
RIR (Reps in Reserve)
How many reps you could still do at the end of a set.
Training Volume
The total work done, usually sets × reps × weight.
Training Frequency
How often you train a muscle or movement per week.
Periodization
Structuring training into phases to peak and avoid plateaus.
Deload
A planned reduction in training to recover and supercompensate.
Compound Exercise
A movement that works multiple joints and muscle groups.
Isolation Exercise
A movement that targets a single muscle around one joint.
Range of Motion
How far a joint moves through an exercise, from full to partial.
Time Under Tension
How long a muscle is loaded during a set, driven by tempo.
Eccentric Training
Emphasizing the lowering phase of a lift to drive growth.
Muscle Failure
The point where you can't complete another rep with good form.
Mind-Muscle Connection
Consciously focusing on the target muscle during a lift.
Supersets
Performing two exercises back-to-back with no rest between.
Drop Sets
Extending a set by reducing weight and continuing to failure.
Warm-Up
Preparing the body for training to improve performance and reduce injury.
Repetition (Rep)
One complete cycle of an exercise, from start to finish.
Set
A group of consecutive repetitions performed without rest.
Rest Interval
The recovery time taken between sets.
Concentric Contraction
The lifting phase of a rep, where the muscle shortens.
Push/Pull/Legs Split
A popular routine dividing training into pushing, pulling, and leg days.
Upper/Lower Split
A routine alternating upper-body and lower-body training days.
Full-Body Workout
Training all major muscle groups in a single session.
Training Split
How you divide muscle groups across your training week.
Rest-Pause Training
Extending a set with brief pauses to squeeze out extra reps.
Isometric Exercise
Holding a static position under tension without movement.
Plyometrics
Explosive jump-based training that develops power.
Unilateral Training
Working one limb at a time to fix imbalances and build stability.
Core Stability
The ability of your trunk to resist movement and transfer force.
Grip Strength
Hand and forearm strength that often limits pulling exercises.
Sticking Point
The hardest part of a lift where the bar tends to stall.
Accessory Exercise
Supporting movements that build weak points around the main lifts.
