There's a specific kind of hesitation people feel the first time they try to build a workout from scratch instead of following someone else's — a blank exercise list is intimidating in a way that following a video isn't. The good news is that building a solid custom workout follows a repeatable process that removes most of the guesswork.
Step 1: Decide the Day's Focus
Before picking a single exercise, decide what this specific session is targeting — push, pull, legs, full body, or a specific goal like conditioning. Every following decision becomes easier once this is fixed.
Step 2: Pick Your Primary Compound Movement
Start with the exercise that best represents the day's focus and delivers the most overall training stimulus — a squat variation for legs, a bench or overhead press for push, a row or pull-up variation for pull. This exercise typically gets the most sets and the freshest effort in the session.
Step 3: Add 2-3 Secondary Movements
Choose exercises that support the same muscle groups from a different angle or emphasis — an incline press to complement a flat bench, a Romanian deadlift to complement a squat. These add volume and address areas the primary lift doesn't fully cover.
Step 4: Finish With 1-2 Isolation Movements
Target any specific muscle that needs extra direct attention — triceps, biceps, calves, rear delts — with straightforward isolation work at the end of the session, when compound-lift fatigue matters less.
Step 5: Assign Sets, Reps, and Rest
Match these to your actual goal (see our guide on hypertrophy vs strength vs endurance training) — moderate reps and rest for general hypertrophy work is a reasonable default if you're unsure.

How SetForge Supports This Process Step by Step
SetForge's manual workout builder is backed by a 500+ exercise library filterable by muscle group, which makes each step above genuinely fast — instead of trying to recall exercise names from memory, you can browse specifically within the muscle group you're targeting at each step of the process. Once built, the workout is saved to your history and ready to log real numbers against the next time you run it, and it fits directly into a larger structured program using SetForge's Program Builder if you want to repeat and progress it on a schedule.
A Complete Example: Building a Push Day From Scratch
- Focus: Push (chest, shoulders, triceps)
- Primary: Barbell or dumbbell bench press — 4 sets of 6-8 reps
- Secondary: Overhead press (3x8-10), incline dumbbell press (3x10-12)
- Isolation: Lateral raises (3x12-15), triceps pushdown (3x12-15)
- Rest: 90 seconds for secondary/isolation, 2 minutes for the primary lift
Common First-Time Mistakes
- Too many exercises — 8-10+ exercises in one session usually means quality drops on the movements that matter most
- Skipping the primary compound movement in favor of only isolation work
- No plan for progression — building the workout without deciding how you'll increase difficulty over time
Frequently Asked Questions
How many exercises should my first custom workout include?
5-6 total is a reasonable starting point — one primary compound movement, 2-3 secondary movements, and 1-2 isolation exercises.
What if I don't know which exercises count as "secondary" for a given day?
Filter SetForge's exercise library by the same muscle group as your primary movement, and choose a variation that hits it from a slightly different angle.
Should I copy someone else's custom workout instead of building my own?
It's fine as a starting reference, but adjusting it to your own equipment, experience level, and goals is what actually makes it "yours" and appropriately challenging.
How do I know if my first custom workout was well-designed?
Log your actual performance and revisit it in a few weeks — if you're able to progressively add weight or reps over time without excessive soreness or fatigue, it's working.
Can I turn a single custom workout into a full weekly program?
Yes — once you've built individual day templates (push, pull, legs, etc.), SetForge's Program Builder can structure them into a repeating multi-week program.
The Bottom Line
Building your first custom workout is far less intimidating once broken into steps: decide the focus, pick a primary compound lift, add supporting movements, finish with isolation work, and assign sets/reps matched to your goal. A filterable exercise library removes the hardest part — remembering appropriate exercise names — leaving you to focus on structure and progression.
