Chubbies Workout & Athletic Shorts â Not Just for Roundhouse Kicks
Comfortable, flexible, aerodynamic and most of all utterly radical. Chubbies gym shorts are everything a short should be and MORE.
As your purveyors of thigh freedom and proper-length menâs shorts, we couldnât just stop at swim trunks and casual shorts. No. That wouldnât be enough.
We said to ourselves âYou know basketball players, Olympic sprinters, & beach volleyball players in the 80s? They looked super cool doing athletic things in short workout shorts. We should bring those to the masses.â And we did.
And we did it In a variety of inseams to match whatever your proper length athletic short is. Whether you want 4-inch workout shorts, 5.5â workout shorts, or 7â workout shorts, we got you. However, if youâre looking for that early 2000s baggy below-the-knee basketball short trend, then we probably donât got you on that.
Once youâve picked the perfect length workout short, your next question is probably, âDo you wear anything under gym shorts?â
And honestly, you should probably wear something underneath. Thatâs why we offer a selection of compression-lined gym shorts. Chafing at the gym is never fun, so we designed perfect compression liners that hug and support all of the places that need to be hugged and supported. We also carry some styles that are unlined as well, so you can make the decision on what to wear underneath.
Below youâll find some more in-depth information about our workout shorts so you can compare them to each other and figure out which short suits your gym short needs the best.
Ultimate Training Shorts
Our most technical short, just got more technical-er...or something like that. These can do it all: theyâre stretchy but durable. Supportive but non-restrictive. And best of all, so buttery-soft that youâll want to work out longer & harder than ever.
Available in 4â & 5.5â inseams
Best For:
- - Training: HIIT, CrossFit, powerlifting, upper body day for the 3rd day in a row.
- - Running: errands, wild, on the treadmill, up that hill.
- - Pickleball/Tennis: Dink your opponent to defeat.
- - Rock Climbing: indoor or outdoor, the number of pockets on these guys will help.
- - Karate: In your basem*nt, of course.
- - Biking/Spinning: Outdoors, in a studio, or in the comfort of your home. Regardless, you're going to look good out of the saddle.
Features:
- 4-Way Stretch Fabric:
- - A polyester/spandex blend that is so dang stretchy, youâll think we made it out of a toy from the 90s.
- Moisture-Wicking Compression Liner:
- - An improved polyester/spandex anti-cafe liner with an improved fit for comfort, it's more supportive than the outer layer, oh, and antimicrobial, so itâll keep not just the sweat away, but also the sweat smell.
