To think some women could lift heavier in the gym?

I go to a strength training class a few times a week. It’s almost always all women, class size is about 15. I’m not especially strong or experienced at lifting weights but I notice I’m always lifting the heaviest (sometimes by a long way) than every other person there. I’m also working to my maximum capacity for the 8-12 reps we’re doing. I’m huffing and puffing and sweating doing bicep curls with an 8kg dumbbell in each hand and I look over and the woman next to me is lifting a couple of 2kg dumbbells with no visible effort at all. I see this in a lot of the women there. They don’t seem to push themselves to their limit or even that close to it. I’m talking about women a similar age to myself that have been going to the gym for at least as long as me. I get some people may not want to push themselves to their max effort for whatever reason, eg. an injury, but I’m seeing lots of women seemingly not putting in half the amount of effort that they seem capable of and over a long period of time. So this makes me think the reason must be they don’t believe they are capable of lifting heavier, or they don’t want to lift to their max ability for some reason. Why do you think this is? Have you experienced this? Do you not work to max capacity in the gym? If not, why not?

So what results do these women want by lifting a weight that (by the looks of it, obviously I can’t know for sure) doesn’t provide any kind of resistance, so therefore doesn’t work their muscles at all? What result are they looking for by doing that?

I have a personal trainer and his recommendation is variety so some days I do very low weight but high repetitions. Constant high weights can strain muscles without proper training.

Do you have a trainer or someone monitoring you at the gym?

LiviaDrusillaAugusta · 09/05/2026 05:39

Perhaps they think your ‘huffing and puffing’ is a little performative. But what you need to do is to ask these people. It’s the only way you will find out

YANBU OP, but unless posters are into strength training they won’t understand. There is little point in lifting weights if the weight you are lifting isn’t heavy enough! It won’t improve your health or protect your longevity.

Also people don’t realise until they start strength training, that it’s almost impossible to “bulk up” as a female! It’s very, very difficult for women to gain significant amounts of muscle so generally they don’t need to worry about that.

I’ve been strength training for many years and lift heavier than OP and I still think she is BU, and I’d suspect the same applies to many women on this thread. It’s very infantilising to assume that women who don’t lift at the standard OP considers acceptable “won’t understand” when she has no idea why they choose to lift the weights that they do. It’s also none of her business or that of anyone else!

I do agree with what you say about women not ‘bulking up’ easily.

stargirl27 · 09/05/2026 05:25

Yes some *people likely could lift heavier in the gym. But they don’t want to for whatever reason. Not sure why this required a thread. FYI lots of other women/people consider the weights you lift to be very light weights. Everyone is entitled to exercise as they wish and lift the weights they want to.

garlictwist · 09/05/2026 05:18

I started doing heavy weights and I got so muscly I stopped. I did not like the way I looked at all.

amargaritaplease · 09/05/2026 04:49

The OP sounds ghastly, casting their eye around during the class and feeling really smug about how great they are.
what an insufferable person

Mt563 · 09/05/2026 04:43

Some women (plenty in this thread) think if you lift too heavy, you'll suddenly get bulky. Which is really not easy as a woman, especially without careful diet management too and, honestly, without steroids. Once you get the physique you want, adjust to maintain. Or to lose slightly if you want less muscle.

Lifting properly (can't say if these women are or not) is so important for women.

SpidersAreShitheads · 09/05/2026 03:56

Ilostallthepens · 09/05/2026 00:02

No, I’d tell you that you can’t out-exercise a bad diet

Wow, OP.

If anyone was in any doubt whether you’re a judgemental prick or not, you’ve just given them the answer.

It’s not about being competitive. People don’t lift weights to compete with each other (unless you’re in a weight-lifting competition!) It’s about improving your fitness, building strong muscles, toning up etc. You’re not going to get those results if you don’t challenge yourself a bit

Those other people are going to be healthier and less likely to cause long term issues than you. If you want to go to the limit for zero reason, like sport or competition, go for it.

ToWhitToWhoo · 09/05/2026 01:56

Unless you're their instructor/ trainer, why should you care?

LiviaDrusillaAugusta · 09/05/2026 01:41

Are you able to elaborate on how it affects you? Presumably you can still do what you do without them putting in full effort? Just think how much more you will get done if you concentrate on your own performance rather than judging others 😬

Judging others in a gym is you being competitive. Have you ever wondered why the vast bulk of trainers in gyms are on the younger side? Most of the ones 50 plus have injured themselves out of the industry.

DinoDoughnut81 · 09/05/2026 01:26

Super judgy. There's a lot of this going around at the moment in women's fitness, lift heavy or don't bother. Don't run or you'll be skinny fat on and on.
I'm glad I don't go to the gym if I'd have to have other women judging me.I do weights at home, I just came back to exercise after 3 years of illness, 2kg was all I could do for exercises like lateral raises and shoulder presses. More for bicep curls, RDLs etc But I wanted to work very steadily up in weight. I wouldn't like being sneered at for being a weakling.
I used to be a super fit cyclist riding 70 hilly miles easily on a Friday afternoon after work. I never saw a person who was riding slower than me, un lycra-ed up and thought why even bother? Or what's the point in only doing a few miles. I was just happy seeing other people out getting some fresh air in. Especially if it was another woman. There are lots of barriers to women doing sport so it's rubbish to see posts like this.
Ultimately you don't know other people's bodies or motivations. Not every person is going for gains and all movement in my opinion is good movement.

The result of having some time to themselves away from the demands of family. Because “going to the gym” is deemed as a more worthwhile use of time than “sitting in my car for an hour listening to an audiobook and eating chocolate”

TurkishDelight9 · 09/05/2026 00:06

Because most women want tone not bulk!
I don't think 8kg is much for bicep curls btw, i use a lot more. I have a job which requires me to be strong though.

I don't think bulk is that likely from lifting heavy weights? Unless someone is actively trying for that & does other measures.

This class is not for women who’ve just started weight-lifting though. It’s for experienced people who are aiming to increase their personal bests (therefore working up to lifting heavier and heavier). That is why I don’t understand why they are not pushing themselves if they chose to go to a class where the whole point is to push themselves. I don’t get why people are not understanding this and keep comparing it to stuff it is nothing like at all or talking as if I’m evil-eying a poor, anxious first-timer whose finally built up the courage to enter the weights section, only be be side-eyed by me, kissing my ‘bicep’ in the mirror, cos I think I’m the dogs bollocks 🤣. That is not anywhere close to the situation I’ve described. Anyway you ain’t getting it don’t seem. And I’m bored of trying to explain it. I guess this one will remain a mystery..

I only compared it in a different post, which you didn't quote, where I compared to people criticising people in marathons for not running the whole time.

It's people thinking they are the universal example. You're not. Leave them alone.

WrylyAmused · 08/05/2026 22:46

FYI, yes this was commonly repeated, esp in the past, but it's not actually true. Women, with lower testosterone, have to work incredibly hard to build muscle bulk. You can lift to your max/to failure and you won't appreciably bulk up. And definition is a function of body composition, so yes you can get some by lifting, but it's generally more affected by diet than exercise.

Exactly, aside from the weird use of slurs, the info us incorrect. The weightlifter Bev Francis shows how hard women who DO want to bodybuild have to work.

Maybe……maybe they don’t want to look like you?

🤷‍♀️

Which would be...?

StephensLass1977 · 09/05/2026 01:05

"I look over".

Stop looking at people. People like you are why some women feel so uncomfortable at the gym and eventually stop attending. Don't be that person.

Jane379 · 09/05/2026 01:04

EarringsandLipstick · 08/05/2026 22:44

I don’t agree with OP (let everyone make their own decision about how they exercise) but this is completely incorrect.

Toning is building muscle, and progressive overload is how it’s done. Big weights don’t result in ‘bulk’ (OP is only talking about 8kg weights anyway). (I strength train).

This! Aside from the homophobic language, it's unhelpful to talk as if lifting heavy weights will give most women results they don't want. Women shouldn't be put off strengthening.

Bull dyke structure? Are you in the 2000s? Reported.

Anyway, as well as being offensive your comment doesn't make sense. Women can push themselves without getting big muscles. And if they want to - why not?

DressOrSkirt · 09/05/2026 01:00

They are probably happy with how they look and feel and just want to stay like that.
Maybe they like the instructor, or their friends go to this class, or it's a convenient time or location.

46 year old mum, active, fit but I suffered a stroke a year and a half ago. Luckily I recovered. If you met me you’d have no idea of what I went through. I’m active but I don’t use anything over 2kg,

You don’t have a clue what people have been through, keep your judgement to your self.

DrJump · 09/05/2026 00:54

Well my goal this year is to do all the reps in my classes. This means I'm choosing the lower weight/easier option so I can do more. I noticed toward the end of last year I was chosing heavy weights/options but only doing 1 or 2 and resting more. I'm spending this 12 months focusing on more reps. Next year I'll increase.

Ilostallthepens · 08/05/2026 22:51

This makes zero sense. I only speak one language because I have no need or desire to speak another one. However, if I paid a hefty monthly fee to go to a Spanish class but spent half the class with my headphones on listening to music and missing half of what was being taught, wouldn’t you question why I bothered to go to the class at all? That’s a much more accurate analogy for this situation

It wouldn’t be any of my business though. Their money, their choice. Keep your beak out, you nosy trout.
