Find the right pair of gym leggings and everything from your first 5K to a heavy squat session instantly feels easier. Get them wrong and you spend the whole workout hauling them up, overheating, or wishing you had somewhere to stash your phone. In this guide, we use the SWEATY BETTY Women’s Power Gym Leggings as a benchmark to explain what really matters in women’s gym leggings, and how alternatives like the All Day range and CloudWeight track trousers fit into your kit bag.
Why performance gym leggings matter
Leggings are often the most hardworking item in your training wardrobe. They need to support muscles, move with you, breathe well and stay put through sprints, squats and stretches. A good pair can make the difference between a session that feels strong and one where you are constantly distracted by fit issues.
Performance gym leggings are designed specifically for movement: they combine stretchy, technical fabrics with thoughtful features such as internal drawcords, secure pockets and carefully chosen inseam lengths. The SWEATY BETTY Women’s Power Gym Leggings are a good example of that philosophy in action, so we will use them to highlight what to look for and how to choose the right style for your training.
If you want a deep dive on how they perform in real sessions, you can read our full review of the SWEATY BETTY Women’s Power Gym Leggings separately. Here, we will stay focused on the buying and usage side.
The Sweaty Betty Power Gym Leggings: key features explained
The Power Gym Leggings are built as an all-round training tight, suitable for runs, classes and strength work. They combine a stretchy, supportive fit with practical storage and sweat management, which is exactly what you should look for if you do a bit of everything.
Supportive stretch and fit
These leggings use a stretchy fabric that is designed to feel ultra-supportive rather than overly soft and slouchy. That supportive sensation is helpful for:
- Reducing bounce during runs and high-impact classes
- Helping muscles feel more stable during strength moves
- Creating a streamlined profile under longer tops and running layers
There is also an internal adjustable drawcord at the waist. This is a detail that many people only realise they are missing once they have tried it; being able to cinch the waistband means you can properly secure the leggings for sprints or burpees without over-tightening the rest of the leg.
Inseam length and coverage
The Power Gym Leggings come with an inseam length of 27″ / 68cm, which sits around full length on many people, particularly if you are average height or a bit shorter. This length works well for:
- Outdoor runs in mixed British weather, where you want some ankle coverage
- Gym sessions in air-conditioned spaces
- Those who dislike leggings that cut off mid-calf
If you are taller, these may feel closer to a 7/8 cut, which many find flattering and cooler for indoor training. It is one of the reasons to pay attention to inseam lengths when comparing leggings; a centimetre or two can change how they feel in real use.
Sweat-wicking fabric and quick drying
The fabric is sweat-wicking and quick-drying, designed for multi-sport use. That matters more than you might think:
- On a treadmill session, sweat is pulled away from your skin instead of building up and feeling clammy.
- In back-to-back classes, quick-drying fabric means you do not stay damp between sessions.
- On outdoor runs, you cool and dry faster when you stop, particularly in a breeze.
While technical fabrics vary between brands, looking for phrases like “sweat-wicking” and “quick drying” is a simple way to filter out purely fashion leggings that may struggle once you push the pace.
Thoughtful storage: side slip and back zip pocket
Legging pockets sound like a small detail until you start using them. The Power Gym Leggings include both a side slip pocket and a back zip pocket, which cover most daily training needs:
- The side pocket is ideal for quick phone access during a gym session, or for stashing a card or pass.
- The back zip pocket is more secure and better for keys or a small card when running outdoors.
If you are moving from older leggings with no pockets, this combination can be genuinely game-changing. It also makes the Power leggings a solid choice for people who like to travel light.
Choosing the right size and rise
Whichever brand you are looking at, getting the right size and rise is as important as picking the right fabric. With performance leggings like the Power, you want a close fit that feels supportive but not restrictive.
How they should feel
When you pull on a new pair, run through a quick check:
- Bend into a squat and a lunge – the waistband should not roll or slide down.
- Lift your knees high – the fabric should move smoothly without cutting in.
- Check the fabric in good light – if it turns see-through when stretched, you may need a different size or style.
The internal drawcord on the Power leggings gives you some leeway between sizes, which is handy if you are between sizes or your waist and hips do not match standard charts.
Considering inseam and body height
With a 27″ inseam, the Power leggings aim at a versatile, ankle-skimming fit for many. But body proportions vary, so it is useful to compare with other cuts:
- Full length: more coverage and warmth; good for outdoor running and cooler studios.
- 7/8 length: visually lengthening and cooler; ideal if you dislike bunching at the ankle.
- Cropped or capri: better for hot-weather indoor workouts but can be less versatile year-round.
If you know you prefer a shorter leg, the SWEATY BETTY Women’s All Day 7/8 Leggings offer a more casual, all-day take on that popular length.
When to choose a performance legging vs a softer lounge style
Not every day calls for maximum support. Many people like to rotate between a performance legging like the Power and softer, more relaxed options for low-intensity days.
Performance days: running, HIIT and strength
For anything that raises your heart rate or involves impact, choose a legging that explicitly targets training. The Power leggings’ combination of sweat-wicking fabric, supportive feel and adjustable waist makes them well suited to:
- Interval runs and tempo sessions
- HIIT, circuits and bootcamps
- Strength training and functional fitness
If that is your regular routine, it is worth prioritising this kind of design. You can learn more about how the Power leggings cope with mixed training in our dedicated write-up – head over to the full SWEATY BETTY Women’s Power Gym Leggings review for in-depth impressions.
Low-intensity days: walking, stretching and recovery
For gentler days, you might prefer something a touch softer, especially if you go from the sofa to a casual walk or stretch session. The SWEATY BETTY Women’s All Day 7/8 Leggings and the SWEATY BETTY Women’s All Day Foldover Waist Trousers sit more on the comfort and lifestyle side of the spectrum.
They are great options if you want something that looks gym-ready but feels more like loungewear, especially for walking, travel, or relaxed yoga sessions. You can still train in them, but if you are doing a lot of sprints or jumps, the firmer hold of the Power leggings is likely to feel more secure.
Building a mix-and-match training outfit
Leggings are just one part of a comfortable training outfit. Choosing tops and layers that complement your leggings will make your whole setup more versatile, especially if you train both indoors and outdoors.
Breathable long sleeves for outdoor runs
If you are pairing the Power leggings with a top for outdoor runs or cooler days, a technical long sleeve makes a big difference. The SWEATY BETTY Women’s Breathe Easy Running Long Sleeve Top is the kind of piece that works well here, designed with running comfort in mind.
Match a sweat-wicking legging with an equally breathable long sleeve and you will avoid the common trap of overheating on top while your legs stay comfortable. This combination is especially handy for shoulder-season runs when a jacket is too much but a vest feels too chilly at the start.
Cosy layers for warm-ups and rest days
For warm-ups, cooldowns and days when you go straight from the gym to a coffee, a soft mid-layer or track trouser can be just as important as your main training legging. Two useful pieces to consider are:
- SWEATY BETTY Women’s Sand Wash CloudWeight Track Trousers – relaxed, lightweight track-style trousers that pair well with fitted leggings for layered commutes or gentler movement days.
- SWEATY BETTY Peaceful Rib Half Zip Sweatshirt – a half-zip that bridges the gap between studio and street, ideal for pulling on over the Power leggings when you head out after a session.
Building this kind of mix-and-match system around your main performance leggings gives you more flexibility; you can adapt to the weather and your energy levels without replacing your entire outfit.
Comparing Sweaty Betty leggings and trousers: which are right for you?
Sweaty Betty’s range covers everything from high-support gym leggings to softer all-day trousers and tops. Using the Power Gym Leggings as a starting point, here is how some of the nearby options compare in everyday use.
Power Gym Leggings vs All Day 7/8 Leggings
If you are choosing between the Power Gym Leggings and the All Day 7/8 Leggings, think about how intense your typical sessions are:
- Power Gym Leggings: More focused on support and training, with sweat-wicking, quick-drying fabric, storage pockets and an internal drawcord. Better for running, HIIT and regular gym work.
- All Day 7/8 Leggings: Prioritise comfort and everyday wear, with a slightly more relaxed, lifestyle-leaning feel. Great for walking, gentle classes and casual outfits.
Many people like to own both: one for serious training, one for when comfort and versatility come first.
Power Gym Leggings vs All Day Foldover Waist Trousers
The All Day Foldover Waist Trousers take the comfort brief even further, using a relaxed trouser shape with a foldover waistband. Compared to the Power leggings, they are:
- Looser through the leg, with a less compressive fit.
- More focused on all-day comfort than intensive training.
- Well suited to travel, casual walks and rest days.
If your priority is support during workouts, stick with performance leggings like the Power. If you want something that feels like a step up from joggers in terms of polish, the foldover trousers are a handy second option.
Where CloudWeight track trousers and the Peaceful Rib half zip fit in
The Sand Wash CloudWeight Track Trousers and Peaceful Rib Half Zip Sweatshirt sit slightly to the side of pure gym wear. They are ideal if you:
- Commute to the gym and want something easy to throw on over your Power leggings.
- Prefer a looser feel on recovery days or casual walks.
- Like your training wardrobe to double as relaxed weekend wear.
In practice, many people build a mini-wardrobe: performance leggings for workouts, a softer or looser bottom for lighter days, and one or two mid-layers that work across them all.
Care tips to keep your gym leggings in top shape
Once you have invested in good leggings, a few simple habits will help them last longer and keep their supportive feel.
- Wash cool: Use a cool or 30°C cycle to protect the stretch fibres.
- Avoid fabric softener: It can coat the fabric and reduce sweat-wicking performance.
- Turn inside out: This protects prints and the outer surface from abrasion.
- Air dry: Skip the tumble dryer where possible to preserve elasticity.
- Rotate pairs: If you train frequently, alternating between at least two leggings gives the fabric time to recover.
Follow the care label on your specific pair and they should keep their shape, colour and support for many training cycles.
Final thoughts: building your ideal training kit
Choosing the right women’s gym leggings is about more than just picking a pattern you like. A supportive, sweat-wicking pair like the SWEATY BETTY Women’s Power Gym Leggings can form the backbone of your training wardrobe, while softer options like the All Day range, track trousers and cosy tops help you adapt to different workouts and moods.
Use the Power leggings as your reference point for what good performance tights should offer, then fill the gaps with pieces that suit your routine, from long-sleeve running tops to relaxed rest-day trousers.
