Your name is called, the clock starts, and you have one minute. You chalk up, step onto the platform, set your feet and pull. Two seconds later the bar is overhead, and everybody looks at the same place: the three lights. White, white, red. Good lift. Every weightlifting meet, from a club meet in a CrossFit box to the Olympic Games, runs on the same short list of written rules: how the snatch and the clean & jerk must be done, how much time you get, how the weights go up and what you’re allowed to wear. Here are the weightlifting rules in plain language, plus the unwritten safety rules every weightlifting gym lives by.

Who writes the rules

Olympic weightlifting follows the International Weightlifting Federation’s Technical and Competition Rules and Regulations (TCRR). USA Weightlifting (USAW) uses them for its meets, from local competitions to Nationals, and the Olympic Games follow them too. So the rules you learn at your first local meet are the same ones the Olympians lift under; only the size of the crowd changes. Squatting, benching and deadlifting under a different rulebook? Powerlifting has its own guide: powerlifting rules.

Two lifts, three attempts each

The snatch comes first, then the clean & jerk, both with two hands. Each lifter gets up to three attempts at each lift. The best good snatch plus the best good clean & jerk is the total, and at IWF events medals are given for the snatch, the clean & jerk and the total in each category. Bomb out (miss all three) in either lift and you have no total.

• The snatch: one continuous pull from the platform to straight arms overhead, catching in a squat or split. You finish standing still, arms and legs straight, feet in line, and wait for the “Down” signal.
• The clean: one pull from the platform to the shoulders. The bar can’t rest on the chest partway up (a “double” or “dirty” clean), and your elbows can’t touch your knees or thighs. When you snatch or clean in a squat, you may rock or swing your body to help yourself stand up.
• The jerk: stand still with knees straight, then drive the bar overhead in one motion. Any dip or knee bend that doesn’t finish as a jerk is a no lift. Before the jerk you may adjust the bar to unhook your thumbs, breathe, ease pain or change your grip width.

What makes a no lift

• A press-out: still straightening your arms after you’ve reached the bottom of the squat or split.
• Touching the platform with anything but your feet, or stepping off the platform.
• Pausing in the pull (“pulling from the hang”) or during the arm extension.
• Uneven or incomplete lockout, or not finishing with feet and bar in line.
• Dropping the bar from overhead before the signal, or letting go of it above shoulder height on the way down.
• Any unfinished attempt once the bar passes knee height.
• Not lifting the bar off the platform before your time runs out.

One exception protects lifters with an old injury: if you can’t fully straighten an elbow, you tell the referees and the jury before the competition starts (and may remind them before each lift), and the jury can ask the competition doctor to check it.

The clock and the lifting order

You get one minute from your name being called to lift the bar off the platform. A warning sounds at 30 seconds; that’s also the “final call” for changing your weight. If you follow yourself (two attempts in a row), you get two minutes, with warnings 30 seconds in and 30 seconds before the end. The clock starts when the announcer finishes calling the attempt or when the loaders leave the platform, whichever comes last.

The bar only goes up. The lifter asking for the lightest weight goes first, and once a weight is loaded and the clock has started, it can’t be reduced. When several lifters want the same weight, the IWF calls them in this order:

1. The lightest weight on the bar first.
2. Then the lowest attempt number (a first attempt before a second).
3. Then whoever lifted earlier on their previous attempt.
4. Then the lowest start number.

Weights, attempts and changes

• 1 kg steps. The bar always weighs a multiple of 1 kg. After a good lift it goes up at least 1 kg; after a miss it stays the same unless you ask for more.
• Declare, then change twice. Before each attempt, you or your coach signs your next weight on your athlete’s card at the marshal’s table, and that declaration allows two changes. To go up, change before the final call; to go down, change before your clock starts. If you’re following yourself, declare within the first 30 seconds or you lose your changes and take the automatic 1 kg jump.
• The 20 kg rule. At IWF events, your opening snatch plus opening clean & jerk must be no more than 20 kg below the entry total you registered with, or the jury removes you from the competition. It stops lifters from sandbagging their entry.
• Minimum bar. The lightest weight lifted at IWF events is 26 kg for men (20 kg bar, collars and two 0.5 kg plates) and 21 kg for women (15 kg bar).
• Ties. If two lifters make the same snatch or clean & jerk, the one who made it first ranks higher; for the total, the tie is broken by who made their best clean & jerk first.

Referees, jury and the “Down” signal

Three referees judge every lift with white (good lift) or red (no lift) buttons. As soon as two agree, the lifter hears and sees the “Down” signal and can lower the bar, in front of the body and without letting go above the shoulders. A jury watches from its own table and can reverse a decision by majority. Meets also run a weigh-in that starts two hours before your group lifts and lasts one hour, and once the athletes are introduced, a 10-minute countdown runs to the start of the session.

The platform, bar and plates

Every competition lift happens on a square platform 4 meters on each side and 10 cm high, with a flat, clear meter around it. The men’s bar weighs 20 kg and the women’s 15 kg, each collar weighs 2.5 kg, and the bumper plates are color-coded: red 25 kg, blue 20 kg, yellow 15 kg, green 10 kg and white 5 kg, then change plates of 2.5 (red), 2 (blue), 1.5 (yellow), 1 (green) and 0.5 kg (white). Heaviest plates go on first so the referees can read the bar. Chalk and rosin are set out by the platform, and a stretcher or backboard must be nearby.

Age groups and weight categories

The IWF recognizes Youth (13–17), Junior (15–20) and Senior (15 and up), counted by year of birth, plus Masters (35 and up); USAW also runs U25 and university events, and Youth Nationals with U11 and U13 groups. As of the 2026 season, the IWF categories in force from August 1, 2026 are:

Group	Men (kg)	Women (kg)
Senior and Junior	60, 65, 70, 75, 85, 95, 110, +110	49, 53, 57, 61, 69, 77, 86, +86
Youth	55, 60, 65, 70, 75, 85, 95, +95	45, 49, 53, 57, 61, 69, 77, +77
LA28 Olympics	65, 75, 85, 95, 110, +110	53, 61, 69, 77, 86, +86

What you can wear

• Costume: a one-piece, collarless weightlifting singlet in any color that doesn’t cover the elbows or knees. Underneath you may wear one tight unitard (which may cover elbows and knees), one collarless T-shirt that doesn’t cover the elbows, and tight shorts no longer than the singlet. A T-shirt and shorts can’t replace the singlet.
• Shoes: “sport footwear”. Lifting shoes are the norm, but any athletic shoe is legal.
• Belt: optional, worn outside the singlet, no wider than 12 cm.
• Knee sleeves: one-piece elastic or neoprene, with no buckles, straps, plastic or wire reinforcement.
• Wraps and tape: wrist and hand bandages of any length, never attached to the bar. Tape on the fingers and thumbs (the hook-grip tape most lifters wear) must not stick out past the fingertips, and no bandage or tape is allowed within 5 cm above or below the elbow.
• Chalk: magnesium carbonate is allowed; oil, grease, talc, cream or water on the thighs is not.

The unwritten rules: safety in the weightlifting gym

• Collars on, every set. Plates sliding off one side can tip the bar.
• Drop only bumpers, only on a platform. Missed snatches and jerks get dumped; that’s what rubber bumper plates are for. Keep the area around the platform clear, and never walk behind or in front of someone who’s lifting.
• Learn to miss. A coach should teach you to push a snatch forward or jump out from under it behind you, and to dump a jerk, before the weights get heavy. The Olympic lifts aren’t spotted; the bail is your safety net.
• Squat inside a rack. For heavy front and back squats, set the rack safeties just below your bottom position.
• Stop when it hurts. Sharp pain, numbness or a joint giving way ends the session; see a sports medicine doctor, physical therapist or athletic trainer. More on our weightlifting injuries page.

Gear that’s legal on the platform

Three things most weightlifters bring to a meet. The SBD 5 mm weightlifting knee sleeves (about $115) are made for the Olympic lifts and sold as IWF compliant. The Gymreapers 18-inch wrist wraps (about $20) are 18 by 3 inches with a thumb loop, handy for jerks; IWF rules put no limit on wrap length, as long as nothing is attached to the bar. And a block of Cannon Sports chalk (eight 2 oz blocks, about $18) for your warm-up room. Our gear page covers shoes and belts.

Weightlifting rules questions

How many attempts do you get in a weightlifting meet?

Three in the snatch and three in the clean & jerk. Your best good lift in each adds up to your total. Miss all three in either lift and you don’t get a total.

What is a press-out in weightlifting?

It’s continuing to straighten your arms after you’ve reached the lowest point of the squat or split in the snatch or jerk. The bar should be locked out as you catch it; finishing the lockout by pressing makes it a no lift.

Can you lower the weight after a miss?

No. In weightlifting the bar only goes up during a session. After a miss you can repeat the same weight or ask for more, and you can lower a declared weight only before your clock starts and only if that weight hasn’t come up yet.

How long do you have to make an attempt?

One minute from being called, with a warning at 30 seconds. If you’re taking two attempts in a row, you get two minutes. If the bar hasn’t left the platform when time runs out, it’s a no lift.

Can you tape your thumbs in weightlifting?

Yes. IWF rules allow tape on the fingers and thumbs as long as it doesn’t stick out past the fingertips and isn’t attached to the bar. Tape and wraps aren’t allowed within 5 cm above or below the elbow.
