As someone who works out five, sometimes even six, times a week, I can't stress enough how important functional and fashionable fit kit is to me. You see, if it isn't functional - that is to say, sweat-wicking, supportive, and breathable, it'll make my session a pain and likely never be worn again. But if it's so highly functional that I couldn't wear it to brunch with friends, I'll likely also swerve it in favour of more fashion-forward designs that look and feel good during workouts, too. Enter stage right: Sweaty Betty gym kit.
The originally British brand has long been one of my go-tos for stylish, compressive and mood-boosting workout gear, and there's a reason their Power leggings and Stamina bra have an almost cult-like following. Their kit really works, you see and is versatile enough to be worn for high-intensity, super sweaty sessions and a casual girls' lunch, too. If you've been considering investing in some new gym kit for a while but are unsure whether you can afford it, now might be a good time to invest, thanks to their Black Friday discounts.
While we don't endorse buying for the sake of it here at MC UK, I can personally attest that I own and love all of the kit below and rave about it regularly to friends and family (the Power shorts, Therma Boost half running zip and Power bra are my personal favourites). The items are high quality - they look good, support you through pretty much any workout (read: running, cycling, strength training, Pilates, hiking and more) and stand the test of time, too.

If you're more in the market for leggings designed for low impact sessions, walking and brunch with your friends, you can't go far wrong with the All Day design. These are a firm favourite of mine - not only because they're squat-proof and ultra-lightweight, but because they're super wearable, too, making them great for any workout.
For super cosy leggings to see you through winter, SB's Therma Boost leggings are some of the best you can buy. An updated version of their bestselling winter run leggings, they're made from temperature-regulating and sweat-wicking materials to offer protection in all elements, plus have two side pockets for your essentials.
If you're a fan of hatha, yin or any type of yoga, these super soft tights from SB are a no-brainer. They feel like butter while still maintaining a sculpting feel, with noticeably flattering seamlines, a super high-waisted design and snug compression.
These flared leggings come in three inseam lengths so you can be sure of a perfect fit. Sweat-wicking and with handy pockets for all your essentials, they're ideal for yoga, pilates, barre, or just relaxing in at home.

This is one of SB's bestselling sports bras, designed for medium-impact workouts. It's sweat-wicking, made from compression technology for max support, and seamless so no chafing here.
This is a great option for runners or those of you who love high intensity workouts. With a stretchy but seriously supportive design, the looped back and adjustable T-bar strap mean it's great for all sessions. I'm a fan of the removable pads, too, meaning you can customise them to fit how you prefer.
Best top and layer discounts:
Trust me when I say you'll wear this workout top on repeat - it's the perfect throw-on-and-get-moving essential and versatile and sweat-wicking enough to wear for pretty much any workout.
As a runner, I can tell you first hand that this is a great workout essential - it keeps you dry and warm and has breathable mesh panels on the back for extra ventilation. Plus, the sweat-wicking fabric is soft and stretchy, meaning it's easy to get on and off post-run when you're sweaty.
When I say I'm obsessed with this jumper - I honestly mean I'm obsessed. The ultimate statement layer, it's warm, stylish, and ideal for day wear or throwing on over your favourite Pilates 'fit.
Unlike your traditional legging-like half zip running layers, this fleece top is super soft and cosy while also being breathable and sweat-wicking well. I like that the zip is well manufactured so it doesn't rub against your skin or cause any chafing during movement, plus that it fits true to size.
This handy and stylish layering piece is now 30% off. It can be worn as a layering piece or alone as a long-sleeved workout top, thanks to its seamless and sweat-wicking finish.
Best accessories discounts:
This is a tote bag with a difference, and a new and improved version of their best-selling design which promises to make carrying your daily essentials from A to B that bit easier. Stylish yet practical, it's made from a super lightweight canvas and has an adjustable shoulder strap so you can tailor it to whatever length you'd like. Plus, it has two pockets for all of your items - one in the main bag compartment and one on the front.
If you're one of the thousands in the UK who's taken up Pilates this year, investing in a good quality pair of grippy socks will make your practice that bit easier. These are incredibly soft thanks to their breathable organic cotton material, wash really well and have an effective grip panel on the sole to make sure you can maintain your pose, whether you're on a mat or Reformer.
