I Tried M&S's New-In Activewear—Here Are My Thoughts

I write this fresh from lamenting my achy muscles to my colleagues. Between reaquainting myself with treadmill sessions and topping up my Spotify with particularly peppy playlists, January’s annual fitness renaissance is in its stride. And if my on-again, off-again relationship with exercise has taught me anything, it’s that there’s no stronger motivator to get back to the gym than a brand-new outfit. So when the task of testing new-season activewear landed on my desk, it proved to be exactly the push I needed.

A long-time devotee of Marks & Spencer for my everyday staples, it felt only right to turn to the brand once again—this time for workout wear. Their activewear collection is extensive, spanning everything from jackets and leggings to trousers and sports bras, and I was genuinely taken aback by just how considered and stylish the offering felt. Armed with the intention of trying some of their chicest bits, I headed to the fitting rooms with enthusiasm. For reference, I tried tops in Medium, UK 10s on the bottom and sports bras in a size Large—all of which fit perfectly (spoiler: one outfit came home with me).

While the premium look and feel stood out immediately, it was the price point that really sealed the deal. With several standout pieces coming in under £30, this is a collection I’d wholeheartedly recommend if you’re keen to refresh your workout wardrobe while January purse strings remain tightened.

1. Funnel Neck Running Top and Wrap Waist Yoga Leggings:

My Review: I was instantly drawn to the thumb-hole detailing on this black quarter-zip running top. There’s something inherently comforting about cocooning your hands—especially when you’re bracing yourself for a cold-weather run. Unsurprisingly, this was the piece I walked out of M&S with. Beyond the thumb holes, I loved the depth of the zip, which can be pulled down to the chest to allow for airflow mid-run. And while jet black might not be the most exciting shade, it’s the colour I gravitate towards time and again—activewear included.

Paired with M&S’s buttery-soft wrap-waist yoga leggings, this duo feels like a reliable foundation for easing back into a fitness routine. Unlike glossy, scuba-style leggings, these have a softer, more matte finish—so that I’d happily style them with knee-high boots on off-duty days.

2. Quilted Longline Wrap Jacket + Waist Flared Leggings:

My Review: For its price, this padded jacket feels surprisingly luxurious. From the diamond-quilted texture and elegant wrap fastening to the piped hem detailing, it’s a piece that wouldn’t look out of place far beyond the gym. The powder-rose hue, combined with practical side pockets, makes it particularly appealing for low-impact workouts and post-class errands alike.

Styled with the coordinating flared leggings and a tonal longline sports bra in a slightly lighter shade, this three-piece ensemble had me seriously considering booking a Pilates class on the spot.
