Bulk Season Essentials: How to Dress When You’re Gaining

The bulk is a mental game. You’re pushing your caloric ceiling, hitting new PRs, and embracing the "blurriness" that comes with true growth. But for the serious lifter, the transition from shredded to "mass monster" can be a hit to the ego. Both men and women want to feel massive, but nobody wants to feel sloppy.

To survive the surplus, you need gear that respects the grind. This is where you lock in your wardrobe to match your ambitions.

Why Do People Wear Oversized T-Shirts in the Gym?

If you’ve spent any time watching high-level bodybuilding prep or powerlifting sessions, you’ve seen the "pump cover." But why do people wear oversized shirts in the gym during a bulk? For men and women who train seriously, it’s about temperature control, joint warmth, and psychological focus.

An oversized fit—like the Lock In Men’s Shirt or the Lock In Women’s Shirt—acts as a barrier. It keeps your muscles warm during long rest periods between heavy sets and allows you to focus on the feel of the contraction rather than checking your midsection in the mirror.

Can You Wear Oversized Shirts to the Gym?

Absolutely. In fact, for many, it’s the ultimate powerplay. Are oversized shirts good to workout in? Yes, provided they are engineered for it. Unlike a cheap, thin cotton tee that gets heavy with sweat and loses its shape, a premium oversized shirt is cut with a "drop shoulder" to accentuate the V-taper for men and provide a powerful, draped silhouette for women, all while providing maximum mobility for overhead presses and squats.

The Best Gym Clothes for Bulking

When you’re gaining, you need pieces that "grow" with you. What type of shirt is best for working out when the scale is moving up? You need heavyweight fabric that drapes rather than clings.

• For Men: You’re looking for a silhouette that screams "power." You want a collar that stays tight and sleeves that hit just above the elbow. Making a powerplay in the gym starts with the Powerplay Men’s Shirt or layering up with the Powerplay Men’s Hoodie.

• For Women: Bulking doesn’t mean losing your aesthetic. A heavyweight pump cover like the Powerplay Women’s Shirt or the Powerplay Women’s Hoodie provides a confident vibe that says you’re here for the numbers. It’s time to lock in and embrace the strength.

Can we wear oversized clothes in gym settings without looking like we rolled out of bed? The secret is the "structured oversized" look. It’s the difference between a shirt that’s simply "too big" and a shirt that is designed for the frames of men and women who lift.

How Do You Tie an Oversized Shirt at the Gym?

For the female lifter who wants to maintain a shape while reaping the benefits of a pump cover, the "front tuck" or a "side knot" is the go-to move. How do you tie an oversized shirt at the gym? Simply gather the excess fabric at the waist and loop it into a secure knot or tuck it into your waistband. This allows women to show off their quad sweep while keeping the upper-body coverage desired during a heavy session.

The Ultimate Bulk Season Uniform

Stop settling for cheap, thin shirts that shrink after one wash. If you’re investing in your nutrition and your coaching, invest in your gear. The Lock In and Powerplay collections are built for the discipline of the "off-season" for both men and women.

Whether you choose the Lock In Shirt, the Powerplay Shirt, or the Powerplay Hoodie, you are choosing quality that lasts. Whether you’re meal prepping for the week or hitting a 5:00 AM leg day, make sure you lock in with gear that reflects the work you’re putting in.
