Intro to kettlebell sport
This page describes kettlebell sport, the organizations that govern it, the lifts and ranking tables those organizations use, and the competition rules and ranking table used by OG Underground.
Section 1
Kettlebell sport is a timed lifting contest. The athlete performs a prescribed lift with one kettlebell or two kettlebells of equal weight for a fixed period, most commonly ten minutes. The object is to complete as many legal repetitions as possible. Each repetition must finish in a correct lockout: the arm or arms straight, the kettlebells stable overhead, the legs and trunk extended, with a brief pause that the judge can see.
The sport is a test of power-endurance, not of a single maximum lift. The load is submaximal. The difficulty is to repeat the same technical pattern under fatigue without losing fixation. Incorrect form is not awarded. A press-out, a short lockout, an extra knee bend, or a kettlebell that is not under control is a no-count.
The classic events are the jerk, the long cycle (clean and jerk), and the snatch. Biathlon combines a jerk set and a snatch set. Competition kettlebells have the same outer dimensions at every weight. Color bands mark the load. OG Underground uses this format for men and women 45 years of age and older.
Section 2
The kettlebell, or girya, appears in a Russian dictionary of 1704 as a cast-iron counterweight used to measure goods. Farmers and soldiers later used the same implements for strength work. The modern sport, girevoy sport, was organized in the Soviet Union in the mid-twentieth century. The first All-Soviet competition of this type was held in 1948. Unified rules, bodyweight classes, and sports classifications followed. The ten-minute time limit and the long cycle as a championship event were established in the 1980s. The first World Championship was held in 1993. Women entered championship competition at the end of that decade.
After 1991 the sport spread beyond Eastern Europe. International bodies published their own rulebooks and ranking tables. The lifts remained the same: jerk, long cycle, and snatch, performed on a platform, with legal repetitions counted by a judge. What changed from one organization to another was the kettlebell weight assigned to each rank, the bodyweight classes, the treatment of veterans, and whether the athlete may set the kettlebell down during the set.
Kettlebell sport is therefore a classified endurance sport with a fixed implement. Rank is earned by completing a required number of legal repetitions, at a required kettlebell weight, inside a required time, under a published ruleset. Those ranks do not automatically transfer from one organization to another.
Section 3
There is no single world governing body. The following organizations are currently active at international or multi-national level. They are listed in alphabetical order. Each publishes its own rules and ranking tables.
OG Underground is not a world federation. Members who want a sanctioned international rank enter that organization’s competition under that organization’s rules.
Section 4
The currently accepted classic lifts are:
Standard competition kettlebells for classic ten-minute events are 8, 12, 16, 20, 24, 28, and 32 kilograms. Traditional professional loads are 32 kg for men and 24 kg for women. Intermediate loads (20 kg and 28 kg) appear in some tables. All competition bells of a given manufacturer share the same outer size. Color coding marks the weight.
A ranking table is a published grid. It states: for this lift, this kettlebell weight, this bodyweight class, and this age group, this many legal repetitions in the time limit equals Rank 3, Rank 2, Rank 1, Candidate Master of Sport (CMS), Master of Sport (MS), or Master of Sport International Class (MSIC). Heavier bells and more repetitions produce a higher rank. The table, not the athlete’s opinion, defines the rank.
Section 5
The rank names are similar. The grids are not. A Rank 1 under one organization is not a Rank 1 under another. The principal differences are as follows.
| Organization | Time | How rank is earned | Age | Bodyweight |
|---|---|---|---|---|
| IKO | 10 minutes (5-minute sprint also used) | Repetitions at a prescribed bell. Professional ranks (CMS, MS, MSIC) at 32 kg men / 24 kg women. Semi-professional and amateur ranks at 24 kg, 16 kg, and 12 kg. Tables built from 2011–2018 competition data. | Open; Legends 50+ and 60+ with lighter bells | Named weight classes |
| IUKL / WKSF / GSU | 10 minutes (WKSF also publishes 12-minute elite coefficients) | Repetitions at a prescribed bell tied to the rank. Men: MSIC and MS at 32 kg; CMS often at 28 kg; Rank 1 at 24 kg; Rank 2 at 20 kg; Rank 3 at 16 kg. Exact cells differ by federation. | Veterans in separate brackets with lighter bells | Weight classes; higher bodyweight requires more repetitions |
| IKSFA | 5 and 10 minutes | Repetitions by category: Health, General Physical Preparation, Sporting Perfection, High Mastery of Sport. MSIC, MS, and CMS only at the heaviest bells. | Masters 40+ / Seniors 55+ | Weight classes |
| IKMF | 10, 30, and 60 minutes | Marathon and Games tables. Top title is Master of Sport World Class (MSWC). Coefficients by kettlebell weight. | Veteran decades V1–V4 | Three broad classes |
IKO is the strictest widely used ten-minute classic standard in this sense: Master of Sport and Master of Sport International Class are available only at professional kettlebells (32 kg men, 24 kg women), and the tables were fitted to recorded international results rather than to round numbers. IKSFA publishes the most complete public numeric grids. IUKL, WKSF, and GSU keep the older Soviet-style pairing of rank with a prescribed bell. IKMF is a separate sport of longer duration.
Example, IKSFA ten-minute long cycle, men, 82 kg class (the published cell nearest 80 kg):
| Kettlebells | Rank 3 | Rank 2 | Rank 1 | CMS | MS | MSIC |
|---|---|---|---|---|---|---|
| 2 × 24 kg | 33 | 45 | 60 | 78 | — | — |
| 2 × 32 kg | — | — | — | 46 | 54 | 71 |
Those figures are IKSFA’s table, not IKO’s. IKO’s published PDF is the document to use if you apply for an IKO sport rank. Ranks do not transfer.
Section 6
World championship classic rules, shared in substance by IKO, IUKL, WKSF, and GSU, are as follows.
Differences that matter in practice:
Classic girevoy sport and set-down-allowed rules must not be mixed on one leaderboard.
Section 7
OG Underground competitions follow classic world-championship rules: ten-minute clock, competition kettlebells of uniform size, visible timer and lockout, one declared weight, chalk only, and the set ends if a kettlebell is placed on the platform. Legal repetitions completed before that moment count. Official lists are separate for men and women. The membership is 45 years of age and older.
Scoring is FairSet. FairSet is one number for one timed set. It is explained on the FairSet page. In brief:
FairSet = repetitions × (bell load)1.50 ÷ (bodyweight in kg)0.88 × age boost (× 1.22 when a gender difference is being scored on one exhibition board)
FairSet is how two athletes of different age, bodyweight, and kettlebell can be compared. Rank is how that score is named. The rank names and the kettlebell gates follow IKO. The number that awards the rank is a FairSet point total calibrated so that the output matches IKO-style professional work: a peak-age athlete of about 80 kg who performs a Candidate Master of Sport long cycle on 2 × 32 kg lands at Candidate; a Master of Sport set on 2 × 32 kg lands at Master; a Master of Sport International Class set on 2 × 32 kg lands at Elite.
Earn the points. Use at least the minimum kettlebell. Both conditions are required.
| OG rank | FairSet points | IKO equivalent | Minimum bells, men | Minimum bells, women |
|---|---|---|---|---|
| Rank 3 | 200 | Sport Rank 3 | 2 × 16 kg | 12 kg |
| Rank 2 | 280 | Sport Rank 2 | 2 × 16 kg | 12 kg |
| Rank 1 | 380 | Sport Rank 1 | 2 × 16 kg | 16 kg |
| CMS | 500 | Candidate Master of Sport | 2 × 24 kg | 16 kg |
| MS | 580 | Master of Sport | 2 × 32 kg | 24 kg |
| MSIC | 750 | Master of Sport International Class | 2 × 32 kg | 24 kg |
Master of Sport and Master of Sport International Class require professional kettlebells, as in IKO. A high FairSet score on a lighter bell does not award those two ranks.
FairSet uses the athlete’s measured bodyweight. The examples below are a translation at a reference bodyweight of 80 kg for men and 65 kg for women, long cycle, ten minutes. If you are this age, use these kettlebells, and complete this many legal repetitions, you have produced the FairSet points for that rank. A lighter athlete needs fewer repetitions. A heavier athlete needs more. The official score is always the FairSet number, not this example grid.
Men, long cycle, 10 minutes, 2 × 24 kg, example at 80 kg bodyweight. CMS is the highest rank available at this bell. MS and MSIC require 2 × 32 kg.
| Age | Rank 3 200 pts | Rank 2 280 pts | Rank 1 380 pts | CMS 500 pts |
|---|---|---|---|---|
| 45 | 27 | 38 | 52 | 68 |
| 50 | 26 | 36 | 48 | 63 |
| 55 | 24 | 33 | 45 | 59 |
| 60 | 22 | 30 | 41 | 54 |
| 65 | 20 | 27 | 37 | 49 |
| 70 | 18 | 25 | 33 | 44 |
Example in plain language. A man, 60 years of age, 80 kg, long cycle with 2 × 24 kg, 54 legal repetitions in ten minutes, has produced 500 FairSet points. That is OG CMS. The same man on 2 × 32 kg needs 35 legal repetitions for the same CMS points, and 40 legal repetitions for Master of Sport. FairSet may place him ahead of a younger heavier athlete on the leaderboard. The named rank still follows the point total and the minimum bell.
These point cuts will be reviewed after the first 50 judged OG sets. They are OG ranks. They are not IKO, IUKL, WKSF, IKSFA, or IKMF ranks.
