How to Build a Workout Routine From Scratch

A good workout routine has six parts: frequency, exercise selection, volume, intensity, progression, and recovery. Get those right and the routine works. Skip any of them and it does not.

Most beginners try to build their first routine by copying an influencer or stacking favorite exercises. The result is random work that produces random results. This guide walks through the six decisions that go into a productive routine in the order you should make them.


Step 1: Pick a Training Frequency

Frequency is the first decision because every other decision flows from it. Pick the number of sessions per week you can realistically complete every week, not the number you wish you could.

Default frequencies that work:

  • 3 days/week: full-body sessions. Best for beginners, busy schedules, and anyone testing whether they will stick with it.
  • 4 days/week: upper/lower split. Best for early intermediates who want more volume.
  • 5 to 6 days/week: push/pull/legs or body part split. Best for advanced lifters who have proven their consistency.

Three or four sessions a week is the sweet spot for the vast majority of lifters. See training frequency.


Step 2: Choose Your Lifts

Every routine should be built around 5 to 7 main compound lifts, with isolation work added on top.

The core compound lifts:

  • Squat (quads, glutes, core)
  • Deadlift (back, hamstrings, glutes, grip)
  • Bench press (chest, front delts, triceps)
  • Overhead press (shoulders, triceps, upper chest)
  • Pull-up or barbell row (back, biceps)

Beginners do all five every week. Intermediates can rotate variations (front squat for back squat, Romanian deadlift for conventional). See compound vs isolation exercises for why these matter.

Isolation work fills in what compounds miss: direct biceps curls, lateral raises, triceps extensions, leg curls, calf raises. 2 to 4 isolation movements per session is the right dose.


Step 3: Set Your Weekly Volume

For each muscle group, aim for 10 to 20 hard sets per week. Beginners start at the low end (8 to 12), intermediates settle around 14 to 18, advanced lifters can push 18 to 22. See how many sets per muscle per week for the full breakdown.

Spread that volume across at least 2 sessions per muscle per week. Hitting chest with 14 sets in one Monday session is far less productive than 7 sets on Monday and 7 on Thursday.


Step 4: Pick Your Rep Ranges and Intensity

Mix rep ranges within the routine. A balanced setup looks like:

  • Heavy compound (3 to 6 reps): main strength driver, top of the workout
  • Moderate compound or accessory (6 to 12 reps): bulk of the volume, main muscle-building zone
  • Higher rep accessory (12 to 20 reps): pump work, joint-friendly volume

All working sets should be taken to within 1 to 3 reps of failure. Lighter sets that stop far short of failure barely contribute to growth. See rep ranges for muscle growth.


Step 5: Plan the Progression

A routine without progression is a routine that produces no results. Decide upfront how you will add weight or reps over time.

The two most common models:

  • Linear progression: add 2.5 kg to the bar every session on compound lifts. Works for beginners for 6 to 12 weeks. Then it stalls.
  • Double progression: pick a rep range (e.g. 5 to 8). Add a rep at the same weight every session. When you hit the top of the range, add weight and drop back to the bottom. Works for intermediates indefinitely. See double progression.

Pick one model. Track every set. If the bar is going up week over week, the routine is working. If not, adjust volume, recovery, or nutrition before changing the routine.


Step 6: Schedule Recovery

A routine is half rest. Sleep, food, and rest days are not optional. Plan them like you plan training.

  • Rest days: at least 1 to 2 per week with no lifting. Walking, mobility, easy cardio is fine. Heavy lifting is not.
  • Sleep: 7 to 9 hours per night. Not negotiable. See sleep and muscle growth.
  • Nutrition: 1.6 to 2.2 g protein per kg bodyweight per day, calories at maintenance or slight surplus for lean muscle gain. See caloric surplus for muscle gain and the TDEE calculator.
  • Deload every 8 to 12 weeks: a week of reduced volume to flush fatigue. See deload weeks.

A Sample Beginner Routine

3 days per week, full body, A-B-A / B-A-B alternating pattern.

Day A:

ExerciseSetsReps
Squat35
Bench press35
Barbell row35
Plank330 to 45 sec

Day B:

ExerciseSetsReps
Squat35
Overhead press35
Deadlift15
Pull-up or lat pulldown38 to 10

Add 2.5 kg to each lift every session as long as form holds. Stay on this for 12 weeks before changing anything. This routine is enough to drive most of your year-one beginner gains.


Common Routine Design Mistakes

  • Random exercises every session. No way to progress. Pick lifts and stick with them.
  • Skipping legs. Half your muscle mass is below your waist. Always include squats or deadlifts. See the beginner mistake list.
  • Too much volume. 25 sets per muscle per session burns recovery. Start at 8 to 12 sets per muscle per week.
  • No progression model. Lifting "what feels right" is not progression. Pick linear or double progression.
  • No tracking. Without tracking, you cannot know if you are progressing.

Frequently Asked Questions (FAQ)

How do I create my own workout routine?
Pick a frequency you can sustain (3 to 4 days/week for most), build it around 5 compound lifts, target 10 to 20 sets per muscle per week, set a progression model, and plan recovery. Track every session.
What is the best workout routine for beginners?
Three-day full-body routine with squat, bench, deadlift, row, and overhead press. Linear progression of 2.5 kg per session. 12 weeks minimum on the same routine before changing.
How long should a workout last?
45 to 75 minutes for most lifters. Less than 30 minutes is usually too short to drive enough volume. More than 90 minutes is usually low intensity or excessive rest.
How many exercises should I do per workout?
4 to 6 exercises per session. One or two compounds, two or three accessory or assistance lifts, one or two isolation movements. More than 8 means too much volume per session.
Should beginners do full body or split routines?
Full body for the first 6 to 12 months. Splits offer no advantage for beginners and miss the high-frequency stimulus that drives early gains.
How often should I change my workout routine?
Every 8 to 16 weeks, and only if progress has clearly stalled. Most beginners stall not because the routine is wrong but because they need more food, more sleep, or more consistency.
Can I build muscle working out 3 days a week?
Yes. Three full-body sessions a week is enough to drive strong muscle growth for any beginner or intermediate. More frequency only helps when you can recover, eat, and sleep enough to support it.
What is the best split for muscle gain?
For beginners, full body 3 days a week. For intermediates, upper/lower 4 days a week. For advanced lifters, push/pull/legs 5 to 6 days. Pick the highest frequency you can recover from and stay consistent on.
