Introducing the Runyon Pump-You-Up™ 7" Sweatshorts — a heavyweight unisex French Terry gym short for women and men and our modern interpretation of the classic American sweatshort. Crafted from soft 14 oz Tri-Blend French Terry with Runyon's original oversized side stash pockets, these versatile workout shorts combine old-school athletic comfort with functional storage designed for modern training and everyday wear.

With a relaxed unisex athletic fit and versatile 7-inch inseam, the Pump-You-Up™ works especially well for women looking for a roomier sweatshort rather than a traditionally fitted women's gym short. Built for strength training, cool-weather running, hiking, yoga, recovery days, travel, lounging, and everyday movement, the heavyweight French Terry provides a soft, comfortable feel with the versatility to move easily between workouts and casual wear.

Our French Terry Workout Shorts

Made from 14 oz Tri-Blend French Terry — 50% Cotton, 40% Polyester, and 10% Rayon — these unisex sweatshorts combine the familiar comfort of cotton with polyester and rayon for a soft, durable, performance-oriented fabric with additional flexibility. The result is a versatile cotton-blend gym short designed for lifters, runners, hikers, and everyday athletes who appreciate the comfort and heritage styling of classic French Terry athletic wear.

The relaxed unisex construction makes these shorts especially versatile for women who prefer more room through the legs and a classic athletic silhouette. The unlined design also allows you to choose your preferred underwear or performance base layer depending on the activity.

This Tri-Blend version is available in Mineral Grey (Heather Grey). For athletes looking for a 100% cotton option, the Pump-You-Up™ is also available in Black, Sierra Sage, and Vintage Navy.

French Terry - Back To That Old School Fabric Technology

French Terry has been used for decades as a heritage athletic and training fabric thanks to its distinctive loop-back construction. The soft interior loops help manage moisture while the breathable knit allows airflow, creating a comfortable fabric for strength training, running, gym workouts, hiking, travel, recovery, and everyday active wear.

Unlike heavily brushed fleece, French Terry provides substantial comfort without the same insulated feel. The cotton/poly/rayon Tri-Blend gives this version a soft hand and versatile performance feel, making it an easy choice for athletes who want a classic French Terry workout short that can move from training to everyday wear.

All About The Details + Original Design

One of the biggest frustrations with traditional athletic shorts is poorly positioned pockets that allow phones and other essentials to swing, shift, or fall out when sitting, training, or moving through exercises. The Pump-You-Up™ addresses that problem with Runyon's original dual outside stash pocket design, providing oversized functional storage without relying on traditional loose inside pockets.

Each pocket is roomy enough to carry a workout towel or water bottle, while still providing space for your phone, wallet, keys, and other essentials. Whether you're lifting weights, running, hiking, traveling, or heading around town, the large side stash pockets provide convenient storage built around an active lifestyle.

A rugged paracord drawcord and elastic waistband provide a secure, comfortable fit, while the 7-inch inseam creates a relaxed athletic silhouette that works across training, running, travel, recovery, and everyday wear.

Designer Commentary

These shorts have become my go-to for the gym, especially when the weather cools down. I've been doing all my strength-training workouts in them. Lately, I've also been trying to incorporate more cotton and natural fibers into my training gear, which is what originally inspired the development of the Pump-You-Up™ Sweatshorts.

The French Terry fabric is great for training because it's soft, breathable, and comfortable without the heavily insulated feel of fleece. This Mineral Grey (Heather Grey) version uses a 14 oz French Terry Tri-Blend combining 50% cotton, 40% polyester, and 10% rayon for a softer blended feel with additional flexibility.

For athletes who prefer 100% cotton, we also offer the Pump-You-Up™ in Black, Sierra Sage (Olive Drab), and Vintage Navy.

As a sweatshort for running, I especially like them in cooler weather. I've used the Pump-You-Up™ for 6–10 mile cool-weather and early-morning runs, and even took them on a 17-mile trail run reaching 6,300 feet elevation on a crisp, dry fall day. The substantial French Terry makes the design particularly well suited to cooler conditions where I want more coverage than a traditional lightweight running short.

They also make a great yoga, recovery, and lounging short because the material is incredibly soft. At home, they're one of those pairs of shorts that are easy to throw on and live in.

At the gym, I usually keep a water bottle in one pocket and a workout towel in the other, and there's still plenty of room for my phone and keys.

We spent months testing and developing these shorts and refining the details. They use the same pocket profile as our Warm-It-Up Jogger Sweatpants, but in a short format that works equally well for training and everyday wear.

What makes the Pump-You-Up™ design unique is the way the outside stash pockets manage everyday essentials. Unlike many gym shorts with loose interior pockets, your phone doesn't simply hang and swing inside the short. This is my revision of the classic American sweatshort — updated around what athletes actually carry and need today.

The goal was to preserve what makes traditional sweatshorts so comfortable while making them more functional for modern training, running, travel, and everyday life.

You'll also be glad to know we sourced Made-in-USA elastics, USA-knitted textiles, USA-webbed paracord, and USA-woven labels.

This short demonstrates the lengths we've gone, whenever possible, to stay true to our mission from day one — supporting American manufacturing while serving the growing community of athletes around the world discovering and wearing Runyon.

Just a reminder: these shorts are not pre-washed, so they'll shrink slightly after the first wash. The dimensions in the Size Chart reflect the expected measurements after washing.

I know you'll love these shorts and can't wait to watch them Pump-You-Up!
