Weight Training for Women: A Beginner's Guide

Why weight training for women is worth it

• It is part of the health guidelines. The NHS advises all adults to do strengthening activities that work all the major muscle groups on at least 2 days a week.
• It helps your bones. The NHS says weight-bearing and resistance exercise "are particularly important for improving bone density and helping to prevent osteoporosis".
• It changes your shape. Cardio burns calories, but lifting builds the glutes, back, shoulders and legs that give you shape as you lose fat.
• It makes daily life easier. Carrying shopping, lifting children and climbing stairs all get easier as you get stronger.

What to train

You do not need dozens of exercises. Cover these movement patterns and you have trained your whole body:

Movement	What it trains	Beginner options
Squat	Thighs, glutes	Goblet squat, leg press
Hinge	Glutes, hamstrings, back	Romanian deadlift with dumbbells, hip thrust
Push	Chest, shoulders, triceps	Dumbbell bench press, push-ups, shoulder press
Pull	Back, biceps	Lat pulldown, seated cable row, dumbbell row
Lunge	Thighs, glutes, balance	Split squat, step-ups, walking lunges

Machines are not cheating. They are easy to learn, safe to push hard and great for beginners. Add one or two smaller exercises each session, such as lateral raises, glute bridges, curls or a plank, for the areas you care most about.

How often, and how many sets and reps

The American College of Sports Medicine's 2009 position stand on resistance training suggests beginners train 2 to 3 days a week, using loads they can lift 8 to 12 times, with multiple sets for muscle growth. A 2016 meta-analysis by Schoenfeld and colleagues in Sports Medicine found that training each muscle twice a week built more muscle than once a week. Full-body sessions two or three times a week do both.

The number of reps is less important than effort. In a 2017 meta-analysis of 21 studies by Schoenfeld and colleagues in the Journal of Strength and Conditioning Research, light and heavy weights built similar amounts of muscle when sets were taken to failure, while heavier weights built more strength. Moderate reps are the practical middle: heavy enough to be efficient, light enough to keep your form safe while you learn.

A simple way to start:

Day	Session
Monday	Full body A: goblet squat, dumbbell bench press, lat pulldown, Romanian deadlift, plank
Wednesday	Full body B: leg press, seated row, shoulder press, hip thrust, split squat
Friday	Full body A again (next week, start with B)

Do 2 to 3 working sets of each exercise, after a lighter warm-up set or two. For how many sets to aim for as you progress, see how many sets per week to build muscle.

How hard? Finish most sets with about 1 to 3 reps left in the tank: the last reps should be slow and difficult, but your form should still be good. If you could have done many more, the weight is too light.

Keep a log. Write down the weight and reps for every set. Next time, try to beat it by one rep or a little weight. That is progressive overload, and it is what turns effort into results.

Your menstrual cycle and training

You may have seen advice to train hard in one phase of your cycle and ease off in another. The evidence does not support strict rules.

• A 2020 meta-analysis by McNulty and colleagues in Sports Medicine reviewed 78 studies. Performance "might be trivially reduced" in the early follicular phase (around your period), but the authors concluded that "general guidelines on exercise performance across the MC cannot be formed" and recommended a personalised approach.
• A 2023 review of the reviews by Colenso-Semple and colleagues in Frontiers in Sports and Active Living concluded it is "premature to conclude" that normal hormone changes across the cycle meaningfully affect strength or muscle gain.

So train consistently and listen to your body. If cramps, fatigue or heavy bleeding make a session hard, lighten it or swap it. Noting your cycle alongside your training log can help you spot your own patterns.

If your periods become irregular or stop while you are training or dieting, speak to your GP. The NHS lists doing too much exercise, sudden weight loss and stress among the common causes, and missed periods are worth checking.

Pregnancy and after birth

The NHS says it is usually fine to keep doing activities you already do during pregnancy, including gym strength training, and recommends 2 sessions of muscle-strengthening exercise each week. It also advises starting any new exercise gently, not lying flat on your back for more than a few minutes in later pregnancy, and avoiding activities with a risk of falling or bumping your tummy.

Every pregnancy is different, so speak to your midwife about what is safe for you, and check with your GP or midwife before returning to training after giving birth.

Nutrition basics

Training builds the muscle. Food supplies the materials.

• Protein. A 2018 meta-analysis of 49 studies by Morton and colleagues in the British Journal of Sports Medicine found the benefit of protein for muscle gain levelled off at about 1.6 g per kg of body weight a day, with 2.2 g as a sensible upper end. For a 65 kg (143 lb) woman, that is about 105 to 145 g a day. Spread it over 3 or 4 meals with a protein food at each. The free protein calculator works it out for you.
• Calories. To build muscle, eat around maintenance or a little above. To lose fat, eat a little below, keep protein high and keep lifting. The calorie and macro calculator gives you a starting point.
• Do not under-eat. Very low calories make it hard to train well and recover, and can affect your periods. If you are always exhausted and your lifts are going backwards, look at your food first.

How to track progress

Strength usually rises first, often quickly. Visible change comes more slowly, so track more than one thing:

• Your training log: more reps or more weight over the weeks is the clearest sign you are building muscle.
• Measurements: waist, hips and thighs, every two to four weeks.
• Photos: taken in the same light and pose, so you can compare them side by side. See how to take progress photos.
• The scale, with care: it cannot tell muscle from fat, so it can stay flat while your measurements and photos change.

Where coaching helps

Starting is the easy part. The hard part is knowing whether you are lifting heavy enough, eating enough, and whether a slow week means something needs to change.

With one-to-one coaching from CoachAk, your training program is written for you, built around your schedule, experience, equipment and any injury history, with sets, reps, effort targets and coaching cues in the app. You get calorie and macro targets, a weekly check-in with written feedback, and you can send form-check videos and messages to your coach directly.
