Why Your Shirt Rides Up During Workouts
You're mid-set, focused on the lift, and suddenly your shirt is bunched up under your arms or creeping up your back. This common gym frustration usually comes down to one of three things: the shirt's fit, the fabric's grip (or lack of it), or how you're wearing it.
The good news is that each cause has a practical fix. You don't need to buy a whole new wardrobe—just adjust your approach to sizing, tucking, and layering.
How the Right Oversized Tee Can Help
- Lock-In 100% Cotton Oversized T-Shirt: The Lock-In is an oversized, boxy tee cut from breathable 100% pre-shrunk cotton (may shrink up to 2% after first wash), 270 GSM and a bold acid-wash finish. Dropped shoulders and the relaxed silhouette frame your physique without getting in the way—perfect as a pump cover or an everyday uniform in and out of the gym. A true oversized fit with dropped shoulders gives your arms full range of motion without the hem riding up. The boxy cut also provides enough fabric to tuck securely if you prefer that look.

Fix 1: Choose the Right Fit for Your Activity
A shirt that's too tight across the chest or shoulders will naturally ride up when you raise your arms. The solution isn't always sizing up—it's choosing a cut designed for movement.
The Lock-In 100% Cotton Oversized T-Shirt is built for lifters. Its oversized, boxy silhouette and dropped shoulders give you room to move without fabric bunching. The fit note says 'oversized by design,' so you can stay true to size for a relaxed look or size down for a tighter fit. If you're doing overhead presses or pull-ups, the relaxed fit will stay put better than a slim-cut tee.
Fix 2: Use the Tuck That Works for You
Tucking your shirt in is the most reliable way to keep it from riding up, but not all tucks work for every shirt or every workout.
For an oversized tee like the Lock-In, try a front tuck: tuck only the front portion of the shirt into your shorts or leggings. This keeps the fabric out of the way during deadlifts and squats while maintaining the relaxed look. For high-intensity training, a full tuck with a snug athletic short or tight waistband works best.
If you prefer not to tuck, choose a shirt with a longer hem. The Lock-In's oversized cut naturally provides more length than a standard tee, which helps it stay in place during movement.
Fix 3: Layer Strategically
Layering a tighter base layer under a looser shirt can prevent riding up. The base layer stays put against your skin, while the outer shirt moves freely over it—no bunching.
A cotton tee like the Lock-In works well as the outer layer over a compression tank or fitted top. The 100% cotton fabric breathes and the 270 GSM weight gives it enough structure to stay in place without clinging.
