Description
Black Gym Shorts Built for Lifting, Conditioning and the Hard Sessions.
RDX T15 Black Gym Shorts are lightweight training shorts made for people who actually want to move in them. Squats, deadlifts, circuits, running, conditioning or a mixed gym session, the slightly stretchy fabric gives you room to move without feeling baggy or getting in the way.
They’re made from 98% polyester and 2% spandex, giving you the durability of a proper training short with enough flexibility to move comfortably through your session.
And here’s the slightly unusual bit. RDX originally designed the T15 around combat training. For us, that’s actually one of the reasons they work so well in the gym.
If you like wearing a fitted layer underneath your gym shorts, the RDX T15 Black Compression Shorts are the obvious partner.
Are RDX T15 Black Gym Shorts good for weight training?
Yes, and this is where we think these shorts deserve far more attention. The T15 Shorts might have its roots in combat sports, but there’s very little about the design that limits it to fighting.
They’re lightweight, flexible and have reinforced stitching, which makes them well suited to weight training, strength work, conditioning, circuits and general gym sessions.
If you’re squatting or deadlifting, you want shorts that let your hips and legs move without constantly needing to adjust them. The small amount of spandex in the material helps give the T15 enough flexibility for exactly that.
How should RDX T15 Black Gym Shorts fit?
These aren’t compression shorts, so they shouldn’t feel skin-tight.
You want a comfortable fit around the legs with enough room to squat, lunge and move freely, while the elasticated waistband and drawstring keep the shorts secure around your waist.
We’d generally recommend choosing the size that best matches your normal waist measurement rather than deliberately sizing up.
Sizes Available: Small, Medium, Large, XL and 2XL.
Always check the size guide before ordering if you’re unsure.
Buds Fitness Owner Liam’s view on these Gym Shorts
I genuinely wore the Blue T15 Shorts when competing in Strongman. Though listed as MMA Fight Shorts, they are in fact the exact same build, exact same product we have just separate them out to ensure they find themselves on the legs of those that will use them.
So why did I wear these T15 Gym Shorts for Strongman? Simply, the lightweight nature mixed with it’s unbelievable Durabilty. If they are durable enough to withstand grappling in MMA, then they are going to be able to hold us to the strain of gym workout.
The Lightweight nature not only provides comfort, it also helps with provides additional mobility, and limits friction. When doing strength training, particularly moving events such as Keg Carries, or Farmers Walks the range of motions means your turn is never restricted.
