How to Track Unilateral Exercises

The cleanest way to track unilateral exercises is to log one set for the exercise, use the weight held or moved by one side, and make your reps represent what each side completed. If your left leg and right leg both did 10 reps with 20 kg dumbbells, log it as 20 kg x 10, not 20 kg x 20 or two separate exercises.

Unilateral exercises are movements where one side of the body works at a time: Bulgarian split squats, lunges, single-arm rows, single-arm cable presses, single-leg curls, step-ups, and similar lifts. They are great for building balanced strength, cleaning up side-to-side differences, and adding useful volume without always loading the spine heavily.

They can also make a workout log messy if you do not decide on a simple rule.

The goal is not perfect accounting. The goal is a log you can compare next week.

The simple rule: log per side

For most unilateral exercises, treat one side as the standard unit.

If you did:

• right arm: 24 kg x 10
• left arm: 24 kg x 10

log:

Single-Arm Dumbbell Row
24 kg x 10

That entry means “10 reps per side.” It keeps your history clean and makes progression easy to read. Next time, you know whether you are trying to get 24 kg x 11 per side, 26 kg x 8 per side, or a cleaner 24 kg x 10 per side.

Do not double the reps just because both sides worked. A set of 10 lunges per leg is not the same thing as a bilateral lift for 20 reps. Doubling the number makes your log harder to compare and can make volume look inflated.

What weight should you log?

Log the external load that one side is actually working against, using the same convention every time.

Here are the most common cases:

• One dumbbell or one cable handle: log that weight. A single-arm row with a 30 kg dumbbell is 30 kg.
• Two dumbbells held during a leg exercise: log the weight per hand if that is how you think about the lift, and keep it consistent. Bulgarian split squat with two 20 kg dumbbells becomes 20 kg x reps per side.
• A barbell unilateral exercise: log the full barbell load, because the whole implement is being moved.
• Machine unilateral work: log the stack or machine setting exactly as shown, then keep using the same machine when possible.
• Bodyweight unilateral work: log 0 kg or bodyweight, then track reps, control, range of motion, and added load later.

The exact convention matters less than consistency. If you log split squats as “20 kg” one week and “40 kg total” the next, your history becomes harder to trust.

Pick a load convention before the set starts so next week’s comparison is obvious.

What if one side gets fewer reps?

Use the weaker or lower-performing side as the logged result.

If your right arm rows 10 reps and your left arm rows 8 reps with the same weight, log 8 reps and add a short note if needed:

Single-Arm Dumbbell Row
30 kg x 8
Note: “right side got 10, left side limited”

This is conservative, but it is useful. The set only counts as a true 10-per-side set when both sides complete 10 reps with comparable form.

This matters because unilateral work often exposes asymmetry. If you always log the stronger side, your progress record becomes flattering but less helpful. The weaker side is usually the side that should decide when you increase load.

Should you start with the weaker side?

Usually, yes.

Starting with the weaker side gives you a clean target for the stronger side. If your left leg gets 9 good reps on split squats, do 9 on the right leg too. That keeps the work balanced instead of letting the stronger side accumulate extra volume every session.

There are exceptions. If one side is weaker because of pain, injury, or a recent issue, do not force symmetry through discomfort. Lower the load, shorten the range, change the exercise, or get qualified help if the pain is persistent.

For ordinary strength differences, though, weaker-side-first is the easiest rule.

How to progress unilateral exercises

Progress unilateral exercises the same way you progress most accessory lifts: small improvements, clean reps, and patience.

A simple progression rule works well:

1. Pick a rep range, such as 8 to 12 reps per side.
2. Keep the same load until both sides can hit the top of the range.
3. Increase the load only when the weaker side reaches the target with good form.
4. After increasing load, let reps drop back toward the bottom of the range.

Example:

Bulgarian Split Squat

• Week 1: 18 kg x 8 per side
• Week 2: 18 kg x 9 per side
• Week 3: 18 kg x 10 per side
• Week 4: 18 kg x 11 per side
• Week 5: 18 kg x 12 per side
• Week 6: 20 kg x 8 per side

That is double progression, just applied with a stricter rule: both sides need to earn the increase.

When to log sides separately

Most lifters do not need separate left-side and right-side entries for every unilateral exercise. It adds friction, clutters the workout, and often makes the log harder to scan during training.

Separate entries can make sense when:

• you are rehabbing a specific side
• one side uses a different load
• one side has a pain or mobility limitation
• you are working with a coach or physio who wants exact side-by-side data
• the difference is large enough that one shared entry hides useful information

If the difference is small, keep one exercise entry and use notes. If the difference changes the plan, split it out.

How this fits in Steady

In Steady, keep unilateral exercises simple: create or choose the unilateral movement, log the working sets normally, and treat the reps as reps per side. Each set already captures the core details that matter for progression: weight, reps, completion, warm-up status, and optional effort data.

Use an exercise or session note when side-specific context matters. For example: “left side limited at 8 reps,” “start left side first,” or “right knee felt better with shorter stance.” That keeps your main log readable while preserving the detail that could affect the next workout.

This is exactly where a focused workout tracker helps. You do not need to turn unilateral work into a spreadsheet. You need consistent entries, a clear history, and enough context to make the next decision.

Common mistakes

The biggest mistake is changing your logging rule every few weeks. Per-side one week, total reps the next, total dumbbell load after that - now the trend is hard to read.

Other common mistakes:

• logging the stronger side instead of the weaker side
• increasing weight before both sides have earned it
• treating loose reps on the weaker side as progress
• adding long notes when a short cue would do
• comparing different machines as if the numbers are interchangeable

Unilateral exercises are already harder to standardize than bilateral lifts. Keep the log boring so the training can be useful.

The bottom line

Track unilateral exercises per side. Log the load consistently, use the weaker side as the performance standard, and increase weight only when both sides meet the target with good form.

If one side needs special attention, use a short note. If the sides are truly on different plans, split them into separate entries. Otherwise, keep the log clean and repeatable.

Steady is built for that kind of practical tracking: fast set logging, useful history, and enough context to keep progressing without cluttering the workout.
