If you want to build muscle, it makes sense to give resistance training a clear place in your routine. That does not mean cardio is bad for women, that every run undermines strength or that you must choose one form of exercise for the rest of your life.
The useful question is what you want your training to do and how the different parts fit together. This guide explains the distinction between strength and aerobic activity, explores common all-or-nothing claims and helps you prepare a realistic conversation about your own programme. It offers general education, not a personal prescription.
Strength training and cardio have different jobs
Resistance training challenges your muscles against a load. That load might come from weights, a machine, a resistance band or your body weight. A programme can be organised around building strength, developing muscle or supporting particular physical tasks, with the details adapted to the person.
Aerobic activity, often called cardio, includes activities such as brisk walking, cycling and swimming. The term covers a wide range of experiences. A relaxed social walk, a challenging bike ride and a running event are not interchangeable sessions simply because they involve movement.
It helps to name the actual activity and purpose rather than use broad labels as a judgement. “I enjoy swimming and want to improve my squat” creates a practical planning question. “Cardio or weights?” can hide the information needed to answer it.
What do public health guidelines recommend?
The NHS activity guidelines for adults aged 19 to 64 recommend strengthening activities involving the major muscle groups on at least two days a week, alongside at least 150 minutes of moderate-intensity activity or 75 minutes of vigorous activity weekly, or an equivalent combination. They also advise reducing time spent sitting or lying down and breaking up long periods of inactivity.
These are population guidelines, not a complete individual programme. Your starting point, health, pregnancy status, disability or recovery needs may mean you need tailored advice. If you are unsure what is appropriate, discuss it with a suitable healthcare professional.
The key point is that strengthening and aerobic activity both have a place in the guidance. You do not need to turn one into an enemy to take the other seriously. A plan can reflect a specific priority while still considering the wider picture.
If muscle growth is your priority, make room for the relevant work
A goal needs time and attention. If building muscle or strength matters to you, look at whether the week includes appropriate resistance training and whether you can recover from the work you have planned. A vague intention to lift “when there is time” may keep getting displaced.
Start by making the priority visible in your diary. Then discuss how the other activities fit around it. The answer should account for their duration, demands and importance to you rather than assume that every form of cardio creates the same problem.
You may need to reduce commitments if the whole week is unrealistic. That is a scheduling decision based on the total picture, not proof that a particular activity is harmful. A manageable programme is more useful than a collection of sessions you cannot consistently support.
Cardio is not a single intensity or experience
When someone says they do “too much cardio,” ask what they mean. How often, how long, how demanding and in what circumstances? Are they enjoying it? Are they training for an event? Are they also managing demanding work, limited sleep or other responsibilities?
Those details matter because labels alone cannot explain why a routine is difficult. A plan with several demanding sessions may need a different discussion from one that includes everyday walking and an occasional enjoyable swim.
The NHS walking guide describes brisk walking as a way to be active and notes that a daily ten-minute brisk walk can contribute to weekly activity. Movement does not have to look like a dramatic workout to deserve a place in your life.
Be cautious with claims that cardio is bad for women
A statement about all women should prompt questions. Which women? Which activity? What amount? What outcome? What evidence? Advice that ignores these distinctions may sound decisive while offering very little help with your actual circumstances.
Be particularly cautious when a post diagnoses a hormone problem from your exercise preferences or suggests that buying a product will correct it. Symptoms deserve appropriate assessment. A short video cannot establish the cause of fatigue, changes in weight or difficulties with training.
You can prefer lifting without needing an alarming story about other exercise. You can also enjoy running without having to defend it against every trend. Choose information that explains its limits and helps you make decisions rather than creating fear.
Build a week around your real constraints
Before choosing sessions, list the time you actually have, including travel and preparation. Consider work, caring responsibilities and the activities you already do. A plan that ignores these commitments is unlikely to become easier simply because it looks balanced on paper.
Then identify your main goal and the activities you want to keep for enjoyment. Discuss the demanding parts of the week with a coach so the plan can be organised sensibly. Leave room to adjust rather than filling every available gap automatically.
For example, someone learning to lift might prioritise coached practice and keep an enjoyable walk with a friend. Someone preparing for a cycling event may give cycling a larger share of the schedule while discussing how strength work fits. The same template does not need to serve both people.
Three useful planning conversations
First, consider the beginner who has joined a gym and feels overwhelmed. Her immediate need may be a clear introduction, manageable appointments and help understanding equipment. Adding every class at once may create confusion rather than confidence. A simple starting plan can be reviewed as she learns.
Second, consider the regular runner who wants to become stronger. The conversation should include her running goals, current schedule and experience with resistance training. There is no need to tell her that an activity she enjoys has become pointless because she now has another goal.
Third, consider the returning exerciser whose available time has changed. She may need to rebuild a routine around a different job or family schedule. The useful question is what can work now, not how quickly she can recreate a former week that no longer fits.
Think about recovery across the whole routine
Training sessions do not happen in isolation. A week can feel demanding because of the combined load of exercise and ordinary life. If you are repeatedly struggling to complete the plan, discuss the pattern rather than assuming that more determination will resolve it.
Keep brief notes about sessions and practical obstacles. You might notice that a late class conflicts with bedtime or that a long journey makes an appointment hard to sustain. These details can point to changes that are more useful than debating which exercise category is best.
Persistent fatigue, pain or other concerning symptoms should be discussed with an appropriate professional. Do not use a supplement purchase or a change of training style as a substitute for assessment when something needs attention.
Food is support, not a reward you earn
Avoid framing exercise as payment for eating. A routine should not require you to calculate whether you have earned a meal. If food or exercise feels governed by guilt, fear or a need to compensate, seek qualified support rather than another restrictive set of rules.
Practical planning can still help. Think about whether your schedule allows regular meals and whether you have food available around busy days. If you need individual nutrition advice for health or performance, work with an appropriately qualified professional.

Let enjoyment count in the decision
An activity can be valuable because you like doing it. The social side of a class, the quiet of a walk or the satisfaction of learning a lift may help make a routine meaningful. Those experiences do not need to be reduced to a competition over which burns more calories.
If you dislike an activity, explore alternatives that fit the purpose with suitable guidance. You do not need to copy someone else’s favourite session. Equally, you do not need to abandon something you enjoy because it is unfashionable in a particular online community.
A goal-focused plan and an enjoyable life can support each other. Be clear about the compromises you are willing to make, and review them if the programme begins to crowd out the things that made you want to be active in the first place.
Review the plan using questions you can answer
At an agreed review point, ask whether you attended the planned sessions, understood the work and had enough time to carry it out. Consider what became easier and what repeatedly caused difficulty. These observations give a coach useful information.
Then ask whether the plan still matches your main goal. If the goal has changed, say so. A programme written for an event may no longer fit once the event is over; a routine built around muscle growth may need adjusting when your availability changes.
Avoid judging the entire approach from one unusually good or difficult day. Look for patterns and discuss them. A thoughtful review is more useful than repeatedly replacing the plan whenever a new headline suggests that everything you are doing is wrong.
Frequently asked questions
Is lifting better than cardio for women?
It depends on the outcome you mean. Resistance training has a clear role when strength and muscle are priorities, while aerobic activity serves other fitness goals. Public health guidance includes both. “Better” needs a defined goal and individual context.
Should I stop running if I want to build muscle?
Not automatically. Discuss your running schedule, strength goal, available time and recovery with a qualified coach. The decision should consider the actual work involved rather than assume that all running and all strength programmes are incompatible.
Does walking count as worthwhile movement?
Yes. Walking can be an accessible way to be active, and brisk walking can contribute towards activity recommendations. Its place in your routine can also include enjoyment, transport and time with other people. It does not need to replace every other form of exercise.
What if I only have limited time?
Start with your main goal and a realistic picture of your availability. Ask for a plan that prioritises the most useful work and can be adjusted as circumstances change. A repeatable routine is a better starting point than an ideal schedule you cannot attend.
