DefinitionA short reference note, not a full lesson.
Definition

A hub listing the named methods of arranging sets, loads, and exercises — most arose from the trial-and-error of lifters rather than from controlled research, and each is a different way to vary intensity and volume.

Detail

The source presents a catalog of resistance-training "systems" — structured ways to combine sets, loads, rest, and exercise pairings. It is explicit that most of these systems "did not evolve through scientific evidence determining which systems of training worked best, but through trial and error of weight lifters who saw results." They are best understood as different tools for applying the underlying principles (especially Principle of Progressive Overload and Principle of Variation of Training) by manipulating the acute variables Intensity and Volume.

The systems documented in this domain:

Key facts

  • Most named systems are empirical (lifter trial-and-error), not research-derived.
  • Every system is a way to vary intensity and/or volume to keep driving adaptation.
  • Choice of system should follow the training goal (strength / hypertrophy / power / endurance).

Principle of Progressive Overload
To keep improving, gradually make training harder than your body is used to: more weight, more reps or more sets. You don't need to add weight every week or go to failure. Small, steady increases you can recover from are what work.
Principle of Variation of Training
Varying the stimulus — load, volume, exercise, even contraction type — is the key driver of adaptation; holding variables fixed causes plateaus.
Intensity
The amount of weight (resistance) lifted — also shaped by speed, reps, sets, rest interval, and workout duration.
Volume
How many — not how heavy. Volume is the total amount of exercises, sets, and reps performed, and moves inversely to intensity.
Accommodating Resistance Training (Isokinetic)
Machines that control the speed of contraction so the limb moves at constant velocity and the muscle is loaded maximally through the full range of motion.
Breakdown Training (Multi-Poundage / Drop Sets / Strip Sets)
A trainee performs reps then immediately continues with descending resistances (helped by spotters), repeated over several sets, to build local muscle endurance.
Cheat System
Deliberately breaking strict form to use a heavier load, so the muscle contracts closer to maximal through a greater range of motion.
Circuit Program
A series of exercises performed back-to-back with minimal rest at light loads — very time-efficient and yields small cardiovascular gains.
Dynamic Constant External Resistance (DCER) Training
The accurate term for free-weight and machine training where the external weight stays constant but the muscle force required varies through the movement.
Exhaustion Set System
Taking sets to exhaustion (failure); current evidence finds stopping 1–3 reps short gives about the same muscle growth, and failure adds no strength benefit while adding fatigue.
Forced Repetition System
After a set to exhaustion, training partners assist just enough to force out 3–4 extra reps, forcing the partially fatigued muscle to keep producing force.
Free Weights vs. Resistance Machines
Neither is definitively superior; choice depends on testing specificity, technique requirements, safety, time, and equipment availability.
GNL Rotational System
A rotational scheme — a few muscle groups per workout with long-term planning — to prevent overtraining and allow high-intensity work for each group.
Heavy-to-Light System (Descending)
After a brief warm-up, the heaviest set is done first and resistance is lowered each succeeding set; research favors it over light-to-heavy for strength.
Isometric Training Method
Contracting muscles against a fixed, immovable resistance; 3–10 s high-intensity holds 2–3 times a week build strength, and holds at long muscle lengths transfer across a much wider range than short-length holds.
Isotonic Training Method
Traditional resistance training with dumbbells, barbells, machines, and pulleys — though the effective resistance is not truly constant through the range of motion.
Light-to-Heavy System (Ascending)
Progressing from light to heavy loads set by set, adding weight until only a few repetitions are possible.
Multiple Set System
Performing several sets per exercise — the base from which most other systems are built — adjustable in load, reps, and sets to match any goal.
Periodization (Cycle Training)
Planned variation of training volume and intensity across distinct phases to drive optimal long-term gains in strength and power.
Positions of Flexion System
Training each muscle from three angles/positions — stretch, midrange, and contracted — for efficient multi-angular development.
Pre-Exhaustion System
Pre-exhaustion means tiring a muscle with an isolation exercise, then going straight into a compound exercise for the same muscle (e.g., leg extensions, then squats). It's a valid variation, but trials show no growth advantage over normal order, and it costs you load on the compound lift.
Push-Pull System
Pairing pushing exercises with pulling exercises so agonist and antagonist groups are balanced and stabilizers are not overworked.
Pyramid (Triangle) System
A favorite of power-lifters and bodybuilders combining ascending then descending loading — reps fall as load rises, then reverse.
Single Set System
One of the oldest systems: a single set of each exercise. It still builds strength and is a legitimate time-efficient option, but multiple sets give a modest, consistent edge from early on.
Split Routine System
Different body parts are trained on alternate days so each can be worked thoroughly at high intensity without overtraining.
Super Set System
Two exercises done back to back with little or no rest, either for opposing muscles or for the same muscle. Supersets save time and build strength and muscle about as well as traditional sets.
Variable Resistance Training (Machines, Cams)
Machines using cams, lever arms, or pulleys that change the resistance to match the muscle's strength curve, so it contracts near-maximally throughout the range of motion.
