THE KETTLEBELL WORKS
Choosing the Correct Kettlebell Weight
Beginner to Advanced Weight-Selection Guide
Choosing the correct kettlebell is one of the most important skills in kettlebell training.
The correct weight should be:
Heavy enough to create the required training effect, but light enough to allow every repetition to be performed with control, correct technique and appropriate speed.
There is no single kettlebell weight that is correct for every exercise.
A person who can comfortably swing a 20 kg kettlebell may only be able to press 12 kg overhead correctly.
Similarly, a kettlebell appropriate for a strength session may be far too heavy for a 20-minute conditioning circuit.
The correct kettlebell therefore depends on five main factors:
Your training experience
The exercise being performed
Your training objective
The number of repetitions or working time
Your ability to maintain correct technique
The Kettlebell Works uses these factors together rather than relying solely on predetermined male/female weight recommendations.
1. The Most Important Rule
Technique determines the weight — not ego.
The kettlebell is too heavy if the weight causes:
loss of posture;
excessive spinal movement;
loss of the hip hinge;
shoulder elevation;
wrist collapse;
excessive leaning;
shortened range of movement;
uncontrolled kettlebell movement;
slower and slower ballistic repetitions;
holding your breath unintentionally;
pain;
loss of balance;
compensatory movement.
When any of these occur, reduce the weight.
A technically correct repetition with a lighter kettlebell is considerably more useful than a poorly controlled repetition with a heavier kettlebell.
2. Understand the Two Main Types of Kettlebell Exercise
Kettlebell exercises broadly fall into two categories.
Controlled Tension Movements
These are relatively controlled strength movements.
Examples include:
goblet squat;
front squat;
strict press;
row;
deadlift;
Turkish get-up;
floor press;
split squat;
carries.
These exercises are normally performed slowly enough that muscular strength is the main limiting factor.
Heavier kettlebells can therefore be used when technique is established.
3. Ballistic Exercises
Ballistic exercises use acceleration, momentum and power.
Examples include:
swing;
clean;
snatch;
high pull;
push press;
kettlebell jerk.
These exercises require significantly more technical competence.
For ballistic exercises, maximum weight is less important than maintaining speed, power and control.
4. Beginner Weight Selection
Beginners should generally begin conservatively.
The objective during the first few sessions is not to determine how much weight a person can lift.
The objective is to develop:
movement quality;
grip;
posture;
breathing;
coordination;
confidence;
correct movement patterns.
A practical starting range using The Kettlebell Works equipment is:
Exercise
Deadlift
Goblet squat
Two-handed swing
One-arm row
Strict overhead press
Floor press
Suitcase carry
Farmer carry
Clean
Turkish get-up
Snatch
Typical Beginner Starting Range
8–16 kg
6–12 kg
8–16 kg
6–12 kg
6–10 kg
6–12 kg
8–16 kg
8–20 kg
6–12 kg
6–12 kg
Not normally introduced until swing and clean technique is established
These are starting ranges rather than rules.
Some beginners will require less resistance while strong individuals with previous resistance-training experience may safely start heavier.
Exercise
Deadlift
Goblet squat
Double front squat
Swing
One-arm swing
Row
Strict press
Clean
Clean & press
Snatch
Turkish get-up
Farmer carry
Double clean
Experienced / Advanced Range
20–24 kg or double kettlebells
16–24 kg
2 × 12 to 2 × 24 kg
16–24 kg
12–24 kg
16–24 kg
10–20 kg
12–24 kg
12–20 kg
8–20 kg
12–24 kg
20–24 kg each hand
2 × 12 to 2 × 24 kg
Advanced trainees may eventually require kettlebells heavier than 24 kg for maximal-strength work.
However, the existing Kettlebell Works inventory provides another progression option:
Double-kettlebell training
For example:
2 × 16 kg = 32 kg total
2 × 20 kg = 40 kg total
2 × 24 kg = 48 kg total
Double kettlebells considerably increase the total training load without requiring a single kettlebell heavier than 24 kg.

5. Advanced Weight Selection
An advanced kettlebell user should select weight according to the purpose of the exercise rather than simply choosing the heaviest available bell.
Typical working ranges within The Kettlebell Works 6–24 kg inventory might include:
Experienced / Advanced Range
20–24 kg or double kettlebells
16–24 kg
2 × 12 to 2 × 24 kg
16–24 kg
12–24 kg
16–24 kg
10–20 kg
12–24 kg
12–20 kg
8–20 kg
12–24 kg
20–24 kg each hand
2 × 12 to 2 × 24 kg
6. Select the Weight According to the Session
This is the most important part of kettlebell selection.
Technique / Foundation Sessions
Objective
Learn or improve technique.
Typical repetitions
5–10 repetitions
Effort
Approximately:
RPE 5–6 out of 10
The participant should feel they could perform approximately another:
4–5 technically correct repetitions.
Recommended load
Use a relatively light or moderate kettlebell.
Typical examples:
6–12 kg beginner
8–16 kg experienced
The movement should feel controlled rather than difficult.
Examples
hinge practice;
goblet squat;
clean technique;
press technique;
Turkish get-up practice.
7. Strength Sessions
Objective
Increase maximal or near-maximal strength.
Typical repetitions
3–6 repetitions
Sets
Approximately:
3–6 working sets
Effort
Approximately:
RPE 7–9
Usually stop with approximately:
1–3 repetitions in reserve.
Example
If you can perform:
12 perfect goblet squats with 16 kg
but only:
5–6 perfect repetitions with 20 kg
then 20 kg may be the more appropriate kettlebell for a low-repetition strength session.
Suitable exercises
goblet squat;
double front squat;
strict press;
row;
heavy carries;
deadlift;
floor press.
8. Muscle Building / Hypertrophy Sessions
Objective
Increase muscle size while developing strength.
Typical repetitions
Approximately:
6–12 repetitions
Higher repetitions can also work, but the resistance must remain sufficiently challenging.
Effort
Approximately:
RPE 7–9
Usually finish with:
1–3 good repetitions remaining.
Weight selection
Choose a kettlebell where:
repetitions 1–5 feel controlled;
repetitions 6–9 require noticeable effort;
the final repetitions are challenging;
technique remains correct.
If you can easily complete 15+ repetitions, the kettlebell is probably too light for the intended hypertrophy stimulus.
9. Strength-Endurance Sessions
Objective
Maintain repeated muscular effort over longer periods.
Typical repetition range
10–20 repetitions
or:
30–60 seconds of continuous work.
Effort
Approximately:
RPE 6–8
Typical weight
Lighter than a pure strength session.
Examples might include:
Beginner: 6–12 kg
Intermediate: 8–16 kg
Advanced: 12–20 kg
depending upon the exercise.
10. Cardiovascular Conditioning Sessions
These sessions use kettlebells to challenge both the muscular and cardiovascular systems.
Typical format
For example:
30 seconds work
followed by:
30 seconds recovery
Weight selection
Use a weight that allows:
consistent movement speed;
correct breathing;
correct posture;
technically identical repetitions throughout the interval.
If technique deteriorates dramatically by the end of the interval, reduce the weight.
11. Fat-Loss / Metabolic Conditioning Sessions
Fat-loss training should not automatically mean using the lightest kettlebell and performing huge numbers of repetitions.
The objective should be to preserve strength and muscle while creating a demanding whole-body training session.
Typical training might include:
swings;
goblet squats;
rows;
presses;
carries;
complexes.
Typical repetitions
8–15 per exercise
or:
20–45 seconds’ work
Effort
Approximately:
RPE 7–8
Practical guideline
Select a kettlebell that allows the participant to complete the whole circuit without technique collapsing.
If the programme contains several exercises using one kettlebell, choose the load according to the weakest exercise, usually the overhead press.
12. Power Sessions
Power training requires speed.
More weight does not necessarily produce more power.
Typical repetitions
Approximately:
5–8 explosive repetitions
followed by sufficient recovery.
Stop the set when:
swing height drops;
movement noticeably slows;
hip snap becomes weaker;
posture changes;
grip begins controlling the movement rather than the hips.
Power work should finish before severe fatigue.
13. Kettlebell Endurance Sessions
These sessions emphasise sustained work.
Examples include:
long swing sets;
snatch intervals;
clean-and-press ladders;
timed complexes.
Weight
Generally lighter than strength work.
Typical effort
Approximately:
RPE 6–8
The correct kettlebell allows the participant to maintain:
breathing rhythm;
posture;
grip;
movement efficiency;
technical consistency.
14. Kettlebell Complexes
A kettlebell complex combines several exercises without putting the kettlebell down.
Example:
5 cleans
5 presses
5 squats
5 swings
The correct weight is determined by the hardest movement within the complex.
For most people this will be:
strict press;
overhead movement;
snatch.
Do not select the kettlebell according to the swing simply because the swing allows considerably more weight.
Example
You may comfortably swing:
20 kg
but only correctly press:
12 kg
For a complex containing both exercises, use approximately:
12 kg
not 20 kg.
15. Double-Kettlebell Training
Using two kettlebells dramatically increases the training challenge.
Examples:
double clean;
double front squat;
double press;
double farmer carry.
Do not simply double your normal single-kettlebell weight.
Someone who goblet squats 24 kg should not automatically begin double front squats with:
2 × 24 kg.
A sensible first progression may be:
2 × 8 kg
or:
2 × 12 kg
and progress from there.
Double kettlebells increase:
total load;
trunk demand;
cardiovascular demand;
grip requirement;
technical complexity.
16. A Simple Kettlebell Works Weight Test
For most exercises, members can use the following method.
Step One
Choose the intended repetition range.
For example:
8–10 repetitions.
Step Two
Select a conservative kettlebell.
Step Three
Perform the set using perfect technique.
Step Four
Ask:
Could I comfortably perform more than 5 extra repetitions?
Yes
The kettlebell is probably too light for that training objective.
Could I perform another 2–3 perfect repetitions?
Yes
The weight is probably appropriate.
Could I possibly perform only one more repetition?
This may be suitable for experienced strength/hypertrophy training but is generally too demanding for beginners, technical sessions or long conditioning sessions.
Did technique deteriorate before completing the target?
Yes
The kettlebell is too heavy.
17. The Green-Amber-Red System
The Kettlebell Works can use a simple three-zone system.
GREEN – Correct Weight
posture remains correct;
full range of movement;
controlled breathing;
correct technique;
final repetitions challenging but controlled;
2–3 repetitions probably remain.
Continue using the kettlebell.
AMBER – Borderline
technique beginning to change;
speed dropping;
grip becoming dominant;
range becoming shorter;
significant straining.
Do not increase weight.
Consider reducing weight for subsequent sets.
RED – Too Heavy
technique breaks down;
uncontrolled movement;
loss of balance;
rounded back;
inability to complete prescribed repetitions;
pain;
jerking or uncontrolled overhead movement.
Stop and reduce the weight.
18. When Should You Move Up a Kettlebell?
Progress when you can consistently complete the required:
sets;
repetitions;
range of movement;
tempo;
rest periods;
with technically correct repetitions.
A useful rule is:
Complete all prescribed work successfully for two or three sessions before increasing weight.
For example:
You currently goblet squat:
16 kg
for:
3 × 10
When you can perform all 30 repetitions with consistent technique and still feel approximately two or three repetitions remain at the end of each set, test:
20 kg
with fewer repetitions.
You might initially perform:
3 × 6 at 20 kg
rather than trying to immediately perform:
3 × 10.
19. Progression Does Not Always Mean More Weight
This is particularly important with kettlebells.
You can progress by increasing:
weight;
repetitions;
sets;
time under tension;
training frequency;
movement complexity;
range of movement;
total volume;
work interval;
density.
Or by decreasing:
rest time.
For example, instead of immediately progressing:
16 kg → 20 kg
you could progress from:
3 × 8 with 16 kg
to:
3 × 10
then:
4 × 10
before moving to 20 kg.

23. Testing Kettlebell Strength
For controlled exercises such as:
strict press;
squat;
row;
deadlift;
experienced trainees can use repetition-maximum testing.
For example:
Heavy
A kettlebell you can perform for approximately:
1–3 technically perfect repetitions
Medium-heavy
Approximately:
4–7 repetitions
Moderate
Approximately:
8–11 repetitions
Lighter endurance load
Approximately:
12–15 repetitions
24. Avoid Maximum Testing on Ballistic Exercises
The Kettlebell Works generally does not recommend testing a true one-repetition maximum for:
swings;
cleans;
snatches.
The risk-to-information ratio is poor.
Instead use a:
Technical Rep Maximum
A Technical Rep Maximum is the greatest number of repetitions that can be completed while maintaining predetermined technical standards.
For example:
16 kg swing
The participant may physically be capable of 35 repetitions.
But if technically correct repetitions begin deteriorating at repetition 22:
Technical Rep Maximum = approximately 21 repetitions.
Training should normally remain comfortably below this point.
22. Why Ballistic Exercises Need Different Weight Selection
A useful distinction is the difference between:
Muscular failure
and
Technical failure.
With a slow strength movement, such as a strict press, muscular fatigue is relatively easy to recognise.
With swings, cleans and snatches, the person may technically still be capable of moving the kettlebell even though movement quality has deteriorated.
For ballistic exercises, the set should therefore normally stop at technical failure rather than absolute muscular failure.
Indicators include:
loss of hip power;
increasingly slow repetition speed;
kettlebell moving away from the body;
excessive arm involvement;
grip deterioration;
poor rack position;
excessive impact on the forearm.
25. Beginner Progression Example
A beginner learning the swing might progress:
Stage One
Hip hinge with no kettlebell.
Stage Two
Deadlift:
8–12 kg
Stage Three
Loaded hinge:
12 kg × 12–15 repetitions
Stage Four
Two-handed swing:
8–12 kg
Stage Five
Swing:
12 kg
Stage Six
Swing:
16 kg
26. Advanced Progression Example
An experienced user might progress a squat from:
24 kg goblet squat
to:
2 × 12 kg front squat
then:
2 × 16 kg
then:
2 × 20 kg
then eventually:
2 × 24 kg
This allows The Kettlebell Works existing equipment range to provide:
up to 48 kg of combined kettlebell resistance.
27. Special Considerations
Weight should be reduced where appropriate for:
new exercises;
unfamiliar movement patterns;
return after injury;
return following long training breaks;
significant fatigue;
high-volume sessions;
technical practice;
older adults new to resistance training;
balance limitations;
mobility restrictions.
A previously strong person may still require a light kettlebell when learning a new movement.
Experience with barbells or machines does not automatically equal kettlebell skill.
28. Pain Is Not a Weight-Selection Tool
Training effort and muscular fatigue are expected.
Joint pain, sharp pain or unusual neurological symptoms are not.
Stop an exercise if it causes:
sharp pain;
sudden joint pain;
unexplained numbness;
significant dizziness;
loss of coordination;
unusual chest symptoms.
Weight should never be increased simply to “push through” pain.
29. The Kettlebell Works Quick Selection Rule
Before every exercise ask four questions:
1. What is the objective?
Technique?
Strength?
Muscle?
Power?
Conditioning?
Endurance?
2. What repetition range am I using?
3–6?
6–12?
12–20?
Timed interval?
3. Can I maintain perfect technique?
If not:
reduce the kettlebell.
4. How many technically correct repetitions remain?
More than 5:
Possibly too light.
2–3:
Usually appropriate.
0–1:
Potentially appropriate for advanced strength work, but too heavy for many other sessions.
Technique breaking down:
Too heavy.
30. The Kettlebell Works Principle
The goal is not to lift the heaviest kettlebell in the room.
The goal is to select the kettlebell that produces the correct training stimulus for that particular exercise and session.
A successful kettlebell user learns to use:
lighter bells for technique and endurance
moderate bells for conditioning and hypertrophy
heavier bells for strength
and
appropriate loads for explosive power without sacrificing speed.
The correct kettlebell is therefore not a fixed number.
It is:
The heaviest kettlebell you can use while still satisfying the technical and physiological objective of the session.
That is the basis of safe, effective and progressive kettlebell training at The Kettlebell Works.
