The alarm goes off before sunrise. Weigh-in is at seven, your group starts at nine. In the car: a singlet, lifting shoes, a belt, chalk, a cooler of snacks and a bottle of electrolytes for the second you step off the scale. Meet day in Olympic weightlifting is a long day built around a few seconds on the platform: three snatches and three clean and jerks, six attempts in all. Getting those seconds right comes down to three things: making weight safely, timing your warm-ups to a board that keeps changing, and eating and drinking well in between. Here’s how it works at every level, from a first local meet to nationals.

General information, not medical or nutrition advice. If you have a health condition, talk to your doctor or a sports dietitian before changing what you eat or drink.

Weigh-in: when and how

Weightlifting has bodyweight categories, and yours is settled on a scale in a closed room with officials watching. Under IWF rules, which USA Weightlifting events also follow, weigh-in begins two hours before your group starts and lasts one hour. So even if you weigh in at the last minute, you have about an hour before the first snatch; weigh in early and you have up to two. Read your meet’s entry information for the exact schedule, and bring everything you plan to wear in case of an equipment check. From August 1, 2026, the IWF categories for senior and junior lifters are 60, 65, 70, 75, 85, 95, 110 and +110 kg for men and 49, 53, 57, 61, 69, 77, 86 and +86 kg for women.

Making weight safely

Cutting weight is common in weightlifting. In a 2023 study of 39 British weightlifters competing under IWF rules, 85% had deliberately cut weight to compete (94% of the women and 77% of the men), usually by about 3.8% of body mass. The most common methods were restricting fluids, gradual dieting and water loading. Asked how cutting felt, the same lifters most often described irritation, hunger, fatigue, anxiety and low mood. In a study of 11 international weightlifters, losing about 4% in six days by cutting food intake by 40% didn’t hurt lifting performance, but it raised stress, lowered recovery scores and left key vitamins and magnesium short. And in a case study of a national-level lifter, a 6 kg loss before nationals came with a drop in thigh muscle size and a total below her goal; the authors advised against losing more than about 3 kg in the last week.

• Pick a category you already live near. The easiest cut is no cut. Change categories over months with gradual dieting, not days. Our weightlifting nutrition page covers categories and eating enough.
• Know your trend. Weighing yourself at the same time each morning in the weeks before shows where you really are. A home scale is a guide; only the meet scale counts.
• Skip the dangerous shortcuts. Diuretics are on the World Anti-Doping Agency’s prohibited list, and sweating off big amounts of water with saunas or plastic suits carries real risk. The American Academy of Pediatrics warns young athletes in weight-class sports away from unhealthy weight-loss methods. Teens should compete at their natural weight.
• Rehydrate first after the scale. The joint ACSM, Academy of Nutrition and Dietetics and Dietitians of Canada position suggests drinking about 1.25–1.5 liters for every kilogram lost, with sodium helping you hold on to it. The International Society of Sports Nutrition’s 2025 statement for weight-class combat sports puts an oral rehydration drink first after weigh-in, then easy-to-digest carbohydrate. With only one to two hours before lifting, a big cut leaves little time to recover.

How the session runs

After athlete introductions, a 10-minute countdown runs before the first lift. All snatches come first, then the clean and jerks. The lifter asking for the lightest weight goes first, and the bar climbs in 1 kg steps; once a weight is loaded it can’t go back down. When your name is called you have one minute to start the lift, or two minutes if you’re following yourself. Three referees judge each lift, and the “down” signal comes when two of them agree it’s good. A miss on all three attempts in either lift means no total.

Warm-up room timing

The warm-up room is where meets are won or lost. Because the order depends on the weights everyone asks for, it shifts as lifters and coaches change their attempts. The goal is to take your last warm-up a few minutes before your opener, not twenty minutes before and not in a panic. A simple pattern many coaches use:

• Count attempts, not minutes. Each attempt takes roughly a minute or so. Your coach watches the attempt board, counts how many lifts are left before you, and times your warm-up jumps to it. Recount after every change.
• Plan the warm-up ladder in advance, from the empty bar to a last single somewhere near your opener, with bigger jumps early and smaller ones late. Write it down for both lifts.
• Open with a weight you could make on a bad day. The opener’s job is to get you a total. Some coaches now use bar speed in warm-ups to help: a 2026 study of 14 young weightlifters found that peak bar velocity on warm-up snatches at 80–90% could estimate their max within about 3–4 kg, though not reliably for every lifter. Use it as a cross-check, not a verdict.
• Between the snatch and the clean and jerk, there’s usually a break. Stay warm, sit down, keep a jacket on, eat a little, and restart your clean and jerk warm-ups early enough to build up calmly.

Fueling between lifts

The ACSM joint position suggests a carbohydrate-based meal 1–4 hours before competing (about 1–4 g per kg of body weight), going easy on fat and fiber to avoid stomach trouble, and drinking about 5–10 mL of fluid per kg 2–4 hours before. With weigh-in two hours before the session, most weightlifters eat a small, familiar meal right after the scale, then graze on snacks like bananas, rice cakes, bagels, sports drinks and gummies. The National Athletic Trainers’ Association advises drinking to thirst when your sweat rate is unknown and not overdrinking.

Caffeine is one of the few supplements the International Olympic Committee’s 2018 consensus rates as having good evidence for performance. It isn’t for everyone: it can cause jitters, stomach upset and poor sleep, it isn’t recommended for teens, and anyone with a heart condition or who is pregnant should check with a doctor first. Most important of all: try nothing new on meet day. Test your meet-day food and drinks at a heavy training session first.

What to pack

A one-piece, collarless singlet that doesn’t cover the elbows or knees (IWF costume rules), a T-shirt if you wear one underneath, lifting shoes, a belt no wider than 12 cm, knee sleeves if you use them, wrist wraps and tape, chalk, a jacket for between lifts, your attempt plan, ID and membership card, food, and a big water bottle. Many lifters also carry an electrolyte mix like Nuun Sport tablets or Skratch Labs Hydration powder for after weigh-in, a 32 oz Nalgene, and a block of Cannon Sports gym chalk (chalk is allowed under IWF rules). A simple home scale like the RENPHO Elis 1 helps track your weight in the weeks before. More options are in our electrolyte powder guide and smart scale guide.

Electrolyte products: follow the label, and check with your doctor or a dietitian if you have high blood pressure, kidney or heart problems, or follow a low-sodium diet. After the meet, the work shifts to recovery. If anything hurt on the platform, read weightlifting injuries. How to peak for the day is on our training page.

Meet day: FAQs

How long before a weightlifting meet is weigh-in?

Under IWF rules, weigh-in begins two hours before your group starts and lasts one hour, so you have at least an hour between stepping off the scale and your first snatch. Check your meet’s entry information.

How much weight is safe to cut for a weightlifting meet?

There’s no universal safe number. British weightlifters in a 2023 study usually cut about 4% of body mass, and many reported hunger, fatigue and low mood. In a case study, the authors advised against losing more than about 3 kg in the last week. Teens shouldn’t cut weight. Talk to a sports dietitian before any cut.

How long do I have to take my attempt?

One minute from being called, under IWF rules. If you’re following yourself (taking two attempts in a row), you get two minutes.

How do I choose my opening snatch and clean and jerk?

Most coaches pick a weight you could make on a bad day, so you’re sure to post a total. Recent training and warm-up feel guide the choice, and some coaches also check bar speed in warm-ups as a cross-check.

What should I eat between the snatch and the clean and jerk?

Small, familiar, carbohydrate-based snacks that sit well, plus fluids. Many lifters use fruit, rice cakes, sports drinks or gummies. Keep fat and fiber low, and only use foods you’ve tried in training.
