Resistance Training Systems for the NASM CPT: Sets, Supersets, Pyramids, and Circuits

The seven resistance training systems on the NASM blueprint, how each arranges sets and exercises, which goals and clients each suits, and how to weigh machines, body weight, and free weights by risk and reward.

Short answer

The NASM blueprint lists seven resistance training systems: single set, multiple set, superset, pyramid set, circuit training, vertical loading and horizontal loading. Each is a way of arranging sets and exercises. A single set suits beginners with little time, multiple sets suit strength and muscle-growth goals, supersets pair two exercises back to back, pyramids change the load from set to set, circuits move through a series of exercises with little rest, horizontal loading finishes every set of one exercise before the next, and vertical loading cycles through the whole workout one set at a time. The blueprint also asks you to weigh machines, body weight and free weights by risk versus reward.

The seven systems on the NASM blueprint

Knowledge statement K49 in Domain 4, Program Design, lists resistance training systems "such as single set, multiple set, super set, pyramid set, circuit training, vertical loading, horizontal loading." K50 adds modalities, "such as machines, body weight, free weights," and K59 asks you to judge the "risk versus reward of different modalities and exercises." Program Design is 20% of the NASM-CPT exam.

SystemHow it is arrangedUsually fitsWatch for
Single setOne set of each exerciseBeginners, clients short on time, maintenance phasesToo little volume for advanced strength or size goals
Multiple setSeveral sets of each exerciseStrength and muscle-growth goalsSession length and accumulated fatigue
SupersetTwo exercises back to back with little or no rest between themTime efficiency, and specific NASM phase designsForm on the second exercise as fatigue builds
Pyramid setLoad rises as repetitions fall from set to set (ascending), or the reverse (descending)Clients who like structured progression within an exerciseThe heaviest sets need full attention and spotting when appropriate
Circuit trainingA series of exercises done one after another with minimal rest, then repeatedGeneral fitness, time-limited clients, groupsFatigue eroding technique late in the circuit
Horizontal loadingAll sets of one exercise before moving to the nextTraditional strength work with full rest between setsLonger sessions, and the same area worked repeatedly
Vertical loadingOne set of each exercise in order, often alternating body regions, then back to the topKeeping the session moving while each region recoversEquipment availability for several stations

ACSM's 2009 position stand on resistance training supports the volume point in the table: it recommends higher-volume, multiple-set programs for maximizing muscle growth. The horizontal and vertical loading descriptions are Passy's plain-language summary of NASM's terms. Confirm the exact definitions in NASM's textbook.

How supersets work in NASM's OPT model

Supersets are the system the OPT model uses most visibly, and NASM uses them in two different ways.

  • Strength endurance (Phase 2). NASM's public OPT page describes pairing a traditional strength exercise with an exercise of similar movement that demands more stabilization, done back to back. An example in that spirit: a leg press followed by a single-leg step-up to balance.
  • Power (Phase 5). The same page describes pairing a near-maximal lift with a similar movement done as fast and explosively as possible at a light load. An example in that spirit: a squat followed by a squat jump.

Outside NASM's phase designs, a superset can also pair opposing muscle groups, such as a row with a press, which saves time because one group rests while the other works. The common thread is the arrangement: two exercises, back to back, then rest.

Matching a system to a goal

The blueprint lists the systems without tying each one to a goal, so the exam leaves the matching to your judgment. Three questions do most of the work.

  1. How much volume does the goal need? Muscle growth favors multiple sets. A busy beginner who wants general fitness can make real progress with single sets or a circuit.
  2. How much rest does the work need? Near-maximal lifts need full recovery between sets, which horizontal loading allows naturally. Lighter work can tolerate the shorter rest of circuits and vertical loading.
  3. What does the setting allow? A crowded gym can make a six-station circuit impossible at peak hours, and a home client may have one pair of dumbbells.

The OPT model's phases make these choices more specific. The OPT model guide explains what each phase is for, and the acute variables and periodization guide covers sets, repetitions, and rest.

Choosing a system for three fictional clients

The clients below are fictional.

ClientGoal and contextSystem that fitsWhy
Grace, 58New to training, two 30-minute sessions a weekSingle set or a short circuit on machines and body weightLow volume and simple equipment while technique develops
Omar, 26Wants more muscle, trains four days a weekMultiple sets, with supersets of opposing muscles to save timeVolume drives growth, and supersets keep sessions manageable
Bianca, 45Experienced, 40 minutes at lunch, a corner of the gym to herselfVertical loading through a lower-body, upper-body, and core sequenceEach region recovers while the others work, so the session keeps moving

None of these is the only right answer. They are defensible because each choice follows from the client's goal, experience, and time. After you can justify each row in a sentence, put the same goal-first reasoning to work on 20 mixed NASM CPT scenarios.

Pyramid sets and volume load, worked through

A pyramid changes the load from set to set. Here is an ascending pyramid on a goblet squat for a fictional intermediate client, with loads chosen for the example only.

SetLoadRepetitionsVolume load (load × reps)
130 lb12360 lb
235 lb10350 lb
340 lb8320 lb
445 lb6270 lb
Total361,300 lb

A descending pyramid runs the same table from the bottom up: the heaviest set first, while the client is fresh, then lighter sets with more repetitions. Volume load is a quick way to compare two sessions. If next month the same four sets total 1,450 pounds, the client has done more work. Whether that is the right kind of more depends on the goal.

Machines, body weight, and free weights: risk versus reward

ModalityRewardRisk or limit
MachinesA guided path, quick to learn, easy to load in small stepsLess demand on stabilizing muscles, and fixed paths may not fit every body
Body weightAvailable anywhere, easy to scale with leverage and tempoHard to load heavily for strong clients
Free weightsMore stabilization demand and closer carryover to daily and sport movementHigher technique demand, and some lifts need a spotter

The blueprint frames this as risk versus reward, not good versus bad. A free-weight squat offers a lot of reward for a client with clean technique and a lot of risk for one whose knees cave under load. The right modality is the one whose reward the client can collect safely today. Spotting and set-up are covered in the exercise technique and cueing guide.

Horizontal and vertical loading differ in one detail: whether the client finishes every set of an exercise before moving on, or moves on after each set. If you keep confusing the two, redraw each arrangement, then check the loading-pattern item in the free NASM CPT set. Its explanation also separates vertical from horizontal loading.
