How to Read a Workout Program: Sets, Reps, Tempo, RIR

Sets and Reps: The Basic Notation

The most common format is sets x reps. Two main conventions:

• 3 x 5 means 3 sets of 5 reps. Same weight, same reps, all sets. Common in strength programs.
• 5/5/5/3/1 means 5 sets, with the rep targets 5, 5, 5, 3, 1, usually with weight climbing each set. Common in ramping or peak protocols.

When a program says 3 x 8 to 12, the rep target is a range. Aim for 12 reps. If you hit 12 with good form and reps in reserve, increase the weight next session.

RPE and RIR

RPE (Rate of Perceived Exertion) and RIR (Reps in Reserve) tell you how hard each set should be. See RPE and RIR explained for the full scale.

A program that says 4x5 @ RPE 8 means 4 sets of 5 reps, each set ending with 2 reps left in the tank.

Tempo: 4 Numbers, 4 Phases

Tempo notation looks like 3-1-1-0 or 3-0-1. Each digit represents seconds in one phase of the rep.

4 digits: eccentric, bottom pause, concentric, top pause.

• First digit = eccentric (lowering): 3 seconds down
• Second digit = bottom pause: 1 second at the bottom
• Third digit = concentric (lifting): 1 second up
• Fourth digit = top pause: 0 seconds at the top

So a squat with tempo 3-1-1-0 means: 3 seconds descent, 1-second pause at the bottom, 1 second up, no pause at the top.

Some programs use 3 digits and skip the top pause. Some use X to mean "explosive" or "as fast as possible." Tempo 3-0-X-0 means 3 seconds down, no pause, explode up, no pause.

See eccentric training for muscle growth for why slow lowering matters.

Rest Periods

Rest is the time between working sets. Common prescriptions:

• Rest 60 to 90 seconds: isolation or moderate work, builds metabolic stress
• Rest 2 to 3 minutes: standard for compound lifts in hypertrophy ranges
• Rest 3 to 5 minutes: heavy strength work in the 1 to 5 rep range
• Rest 5+ minutes: maxes and singles, full recovery between attempts

Cutting rest short on heavy compounds drops the bar weight on subsequent sets. Going too long on isolation work blurs the session. Programs typically write rest into the notation explicitly.

Putting It Together: A Real Example

Here is a typical line from a hypertrophy program:

Squat: 4 x 6-8 @ RPE 8, tempo 3-0-X-0, rest 2-3 min

Translation:

• 4 working sets
• 6 to 8 reps per set (target the top, work toward 8 before adding weight)
• RPE 8 means stop each set with 2 reps in reserve
• Tempo: 3 seconds down, no pause, explode up, no pause at top
• 2 to 3 minutes rest between sets

If you can execute that without thinking, you can execute almost any program. See build a routine for the broader framework.

Progression Notation

Programs include progression rules, usually in plain English at the top:

• Linear progression: "Add 2.5 kg per session when all sets hit the prescribed reps."
• Double progression: "Stay at the same weight, add 1 rep per session until you hit the top of the range, then add weight and start over." See double progression.
• Percentage-based: "Week 1 at 70 percent of 1RM, week 2 at 75 percent, week 3 at 80 percent, week 4 deload at 60 percent." See wave loading.

Programs that do not specify progression are incomplete. Without progressive overload, no program produces lasting results.

Common Symbols and Abbreviations

If a program uses an abbreviation you do not recognize, look it up before guessing. Programs are precise. Treat them that way.

Reading a Full Program Layout

A typical week looks like this:

DAY 1: UPPER

A1) Bench Press: 4 x 5 @ RPE 8, tempo 2-0-X-0, rest 3 min
A2) Pull-up: 4 x AMRAP, rest 90 sec
B1) Incline DB Press: 3 x 8-12 @ RPE 8, rest 2 min
B2) Barbell Row: 3 x 6-10 @ RPE 8, rest 2 min
C1) Lateral Raise: 4 x 12-15 @ RPE 9, rest 60 sec
C2) Triceps Pushdown: 4 x 10-15 @ RPE 9, rest 60 sec

The letter-number pairing (A1/A2, B1/B2) means those exercises are supersets or done back-to-back. A1 and A2 alternate, then move to B. Most programs use this format to fit more volume into a shorter session.

Common Reading Mistakes

Treating rep ranges as fixed. "8 to 12" means aim for 12. If you only got 8 with full effort, the weight is too heavy.

Ignoring RPE. A "4x5 @ RPE 7" set is light. A "4x5 @ RPE 9" set is brutal. Same set/rep prescription, completely different effort.

Skipping tempo. Tempo prescriptions exist for a reason. Going faster than prescribed turns a hypertrophy set into a strength set and changes the stimulus. See eccentric training for what controlled tempo actually builds.

Cutting rest periods. Running through rest periods on heavy compounds drops the bar. The recommended rest is based on the work-to-recovery ratio. Respect it.
