How much weight should a beginner lift? Numbers by exercise

That's a first guess, and a guess is all anyone can honestly give you without watching you lift. Someone who hauls bags of potting soil every weekend and someone who hasn't carried anything heavier than a laptop in ten years are both beginners, and they won't start in the same place.

So here's the table to get you close, a three-set test that turns the guess into your number, and the fix for the thing that trips almost everyone up a few weeks in: the next dumbbell up is a much bigger jump than it looks. If your number turns out small, that's fine. Nobody's grading it, and it won't stay small for long.

Starting weights by exercise

These are our coaching starting points, not research. Each one is a weight to try, not a weight you ought to be able to lift. Weights are per hand unless it says one dumbbell.

A few things to know about the table:

• The pattern matters more than the exact numbers. Small muscles (shoulders, arms) take the lightest weights. Big ones (legs, back) take about double or more. That's why one pair of dumbbells rarely suits every move.
• Pick your end of the range. Start at the top if you're bigger, or strong from a physical job or a sport. Start at the bottom, or with no weight at all, if you'd rather ease in. That's a sensible choice at any age.
• Both units are the nearest common dumbbell sizes, not exact conversions. One kilo is 2.2 pounds.
• No weights yet? Filled water bottles work for a first try. A 2-litre bottle weighs about 4.4 lb (2 kg).
• Two moves that sound fancier than they are. A goblet squat is a squat holding one dumbbell against your chest, like the photo further down. A Romanian deadlift is bending forward from the hips with a flat back, letting the weights slide down the front of your thighs, then standing up again.

At a gym with a barbell? A standard bar weighs 45 lb (20 kg) before any plates go on. If you're active and new to lifting, the empty bar is a fair first test for squats and bench press. If it's too heavy, that's common: many gyms have a 33 lb (15 kg) bar or lighter fixed barbells, and the dumbbell moves in the table train the same muscles. Deadlifts from the floor need plates on the bar to raise it to the right height, so people usually start those at around 65 lb (30 kg) all in, or learn the movement with dumbbells first.

On a machine? The same test works on a weight stack. Start with the pin near the top, where the plates are lightest, and write down the machine as well as the number, because stacks differ between brands.

One thing before you test. If you have a heart condition, blood pressure that isn't under control, osteoporosis, a recent operation, or a joint that hurts when you put weight through it, ask your doctor or physio which moves and loads suit you first. And if you're starting from scratch later in life, starting to lift at 50 with zero gym background walks through the first month.

Find your number in three sets

Do this the first time you try each exercise. You only need it once per move.

1. Do 5 easy reps with something you know is light

   Body weight, or the bottom of your range. This is a rehearsal. You're learning where your feet go and what the move feels like, not testing anything.

2. Rest a minute, then do 10 reps with your first guess

   Take it from the table. Move at a steady pace, lowering for about two seconds, and keep counting even when it gets boring.

3. Read the set

   Check what you felt and saw against the table in the next section: too light, about right, or too heavy.

4. Adjust once and try again

   Go up or down one weight, rest a couple of minutes, and do another 10.

5. Stop after three sets and write the number down

   Still not sure? Take the lighter of the two. Your next session will tell you more than a fourth test set today.

Why 10? The American College of Sports Medicine suggests beginners use a weight they could lift 8 to 12 times at most,¹ and stopping at 10 with a couple still in you is a slightly gentler version of that. It's also long enough to show you how a weight really behaves. Almost anything feels fine for five reps. It's reps 7 to 10 that tell the truth.

How to read your set

Pain is a different signal from effort. A muscle working hard is fine. A joint that pinches or aches is not, so stop that exercise for the day rather than pushing through. Soreness the next day is a third, separate thing, and a less useful one than most people think (what DOMS does and doesn't mean).

Don't worry if "2 or 3 left" feels like a wild guess. It is, for everyone at first. In one study, 81 adults guessed how many reps they had left in sets of 10. Near the end of a hard set they were within about a rep, but with seven to ten reps still to go they were off by more than two, and experienced lifters guessed no better than newer ones.² That's why the table above leans on things you can see and feel, like reps slowing and form changing, and not just the number.

The guessing gets better with practice. A quick way to train it: now and then, on a safe move like a biceps curl, keep going past 10 until the reps slow right down, and count how many you really had. Rating effort with reps in reserve goes further into this.

Form is harder to judge on yourself, because you can't see your own back. Prop your phone on the floor, side on, and film one set. You'll catch a lot: heels lifting, a back that rounds, a press that drifts forward. Why form breaks under fatigue explains what you're looking at.

Light is fine, as long as it gets hard

Most advice on this question warns you about lifting too heavy. The research points the other way. Left to choose their own weights, people pick about half of the most they could lift once (53% on average across 18 studies), and that barely changed with experience, age or sex.³

That isn't a disaster. The same reviewers thought loads like that, lifted for 5 to 15 reps, are enough to build muscle and strength in beginners. The newest American College of Sports Medicine position stand agrees: muscle grows across a huge range of loads, light to heavy (heavier ones help more with pure strength), and stopping with 2 or 3 reps in reserve is one way to put in enough effort.⁴ There's more on that in how close to failure you need to go.

So the mistake to watch for isn't a light weight. It's a light weight that never gets hard. If your tenth rep feels like your first, the set did less for you than it could have. Start light, then let the test nudge you up until the last few reps ask something of you. If you suspect you've been playing it safe for years, why women over 50 should lift heavier than they think is worth a read, whoever you are.

When the next dumbbell is a big jump

Two weeks in, your 5 lb (2.3 kg) curls feel easy, so you pick up the 8 lb (3.6 kg) pair and get five reps. You didn't get weaker. The new pair is 60% heavier.

The usual guideline is to add 2 to 10% at a time, once you can do a rep or two more than your target.¹ At the light end of a dumbbell rack, the next step is often five times that:

• 5 lb to 8 lb dumbbells: 60%
• 4.4 lb to 6.6 lb (2 to 3 kg) dumbbells: 50%
• 6.6 lb to 8.8 lb (3 to 4 kg) dumbbells: 33%
• 10 lb to 12 lb dumbbells: 20%
• Empty 45 lb (20 kg) bar plus the two smallest plates: 11%
• The step guidelines suggest: 2 to 10%

Our arithmetic. Guideline step from the American College of Sports Medicine, 2009

Kettlebells are steeper still: going from 18 lb (8 kg) to 26 lb (12 kg) is about half as heavy again. On a barbell, the smallest plates (5 lb or 2.5 kg in total) are only 4% once there's 135 lb (60 kg) on it. The jumps shrink as you get stronger. It's the first few weeks where they bite.

The fix is to add reps before you add weight. Coaches call it double progression. Here's what it looks like for shoulder presses with 8 lb (3.6 kg) dumbbells, three sets, twice a week:

Once you can do 12 on every set, move up one weight and drop back to about 8. Then build back up to 12. The same works in kilos: 4 kg for three sets of 12, then 5 kg for about 8 or 9. Slept badly or had a week off? Drop back a weight for a session. That isn't going backwards.

If even that jump is too big, two more tricks:

• Mix your pairs. Do your first set with the heavier pair and the rest with the old one. Next time, two sets heavy. Then all three.
• Make the same weight harder. Lower it over three seconds, pause at the bottom, or add a set. Progressive overload at home without adding weight has a full menu of these.

Write down what you did each session, so you always know what to beat next time (progressive overload without the spreadsheet keeps that simple). Expect the numbers to climb quickly at first, partly because you're getting better at the movement itself (why early strength gains are mostly your nervous system), and then more slowly. Both are normal. If you're kitting out a room at home, the first $300 of a home gym covers which dumbbells are worth buying.

What changes when a coach watches the set

Everything above works on your own and costs nothing but a notebook. It gets hard in three places: you can't see your own back, "2 or 3 left" is a guess for everyone at first, and on a tired evening the person deciding whether to try the heavier pair is the person who'd rather not. One study hints at what an outside eye does. Women who trained with a personal trainer picked heavier weights for a set of 10 than women who trained alone, about 51% of their max against 42%.⁵ It compared two groups, so it can't prove the trainer caused the difference, but it points the same way as the 53% finding above. On your own, the weight tends to stay light.

That's the job Bespoke Fit is built for. Every session is a live 1‑on‑1 video call with your own coach, in our app on iPhone, Android or a browser. Here's the three-set test with a coach on the call. You prop your phone on a shelf, side on, and do five easy goblet squats. Your heels lift on rep three, and your coach says "sit back, weight in your heels" while you're still in the rep, not a day and a half later from a video you sent in. Your 10 with 12 lb (5.5 kg) move cleanly, so they say go up. With 15 lb (7 kg), reps 8 to 10 slow down but still look like rep 1, and they tell you that's your number. You're wearing an Apple Watch or a Bluetooth heart rate strap, so they can see your heart rate live too, and when it's slow to come down between sets, you get a longer rest. One session, and nobody guessed.

The weeks after are where it adds up:

Each coach has 12 members at most, and we hold to that when we assign coaches. It's why your coach remembers your rows went slowly on the left side last week: they wrote that session and watched it. You don't pick from a list. You start with a 30-minute call with a head coach, who matches you to a coach.

It costs $299 a month after 14 days free, and the 14 days start at your first session. That's one flat price for as many sessions as you book, each 45 to 90 minutes, and most people settle at about an hour. At three one-hour sessions a week, that's about $23 a coached hour. An in-person trainer in the US averages $50 to $90 for a single session.⁶ Paying by the session makes every extra workout a decision about money. Here a third or fourth session in a week costs nothing extra, so in the weeks you're learning new lifts, your coach plans what you need.

If you read the test above and thought "I can do that", you probably can. Film a set now and then, keep the log, and you'll do well for free. We're worth it if you'd rather someone else made those calls and you'll train at least twice a week. We're the wrong pick if $299 a month is a stretch, or if you want someone beside you to spot a heavy barbell, which nobody on a video call can do. How a session works walks through the rest, and can a trainer really check your form over video covers what a camera shows and what it misses.

Common questions

What dumbbells should I buy as a beginner? Two pairs beat one. A light pair for arms and shoulders, around 5 to 8 lb (2 to 4 kg), and a heavier pair for legs and back, around 12 to 20 lb (6 to 10 kg), cover most beginner moves. If you'd rather buy once, a pair of adjustable dumbbells covers the whole range and you won't outgrow it in a month.

Will light weights tone me instead of bulking me up? Toning isn't a separate thing that light weights do. The toned look is a bit more muscle with a bit less fat over it, and any weight that makes your last few reps hard builds that muscle. Bulking up by accident isn't a real risk either. Muscle grows slowly, even for people trying hard to add it.

Should I be sore the next day? A little soreness after your first few sessions is normal, especially after a move you've never done. It isn't proof the workout worked, and it fades as your body gets used to training. If you can barely get down the stairs, the weight or the number of sets was too much, so go lighter next time.
