What to Wear to HIIT Class: The Beginner Kit That Actually Works

What you wear to a HIIT class needs to survive about 30 minutes of jumping, burpees, kettlebell swings, and floor work. The kit that works: a fitted moisture-wicking top, a short or fitted bottom that does not ride up, supportive cross-training shoes, and (for women) a high-support sports bra. Cotton tees and baggy gym shorts are not the move. Here is the full beginner kit, broken down by piece, with the fabric and fit details that actually matter on the floor.

The Top: Fitted, Moisture-Wicking, Not Cotton

The top is the piece you sweat through first. The goal: pull moisture off the skin, dry fast, and stay in place during inversions, burpees, and bent-over rows. The materials that hit:

• Performance polyester / poly-spandex. Fast-drying, slick feel, breathes well. The Sport-Tek Men's Moisture-Wicking Tee and Ladies' Moisture Wicking Tee are the workhorses here.
• Triblend (cotton + poly + rayon). Softer hand, dries faster than 100% cotton, drapes better. The Next Level Premium Triblend lines work for HIIT athletes who hate the slick feel of pure performance fabric.
• Performance long sleeve for winter classes. The Sport-Tek Men's Moisture Wicking Long Sleeve covers chilly mornings without overheating mid-circuit.

Avoid 100% cotton tees, oversized graphic tees, and anything you have to keep tugging back into place mid-set.

The Bottom: Shorts or Fitted Joggers

For HIIT, the bottom needs to clear box jumps, burpees, kettlebell swings, and lateral movement. Two options work:

• Shorts. Men: 5 to 7 inch inseam, lined. The Bear Grips Men's Performance Training Shorts and Sport-Tek Athletic Mesh Shorts both work. Women: a 3 to 5 inch fitted short (Sport-Tek Ladies 3" Fitness Short or Bear Grips Women's Signature Biker Shorts) avoids the ride-up problem on jumping movements.
• Fitted joggers or leggings. Men: Bear Grips Performance Joggers or Cotton Heritage Premium Fleece Joggers. Women: Bear Grips Signature Seamless Leggings or High-Waist Pocket Leggings.

Avoid loose basketball shorts (they ride up on box jumps), regular sweatpants (snag on equipment), and anything with a zipper or pocket on the thigh that bangs against equipment.

Women: Sports Bra Is the Most Important Piece

If a woman is going to HIIT for the first time, the single most important purchase is the sports bra. HIIT involves jumping jacks, box jumps, sprints, and high-impact compound movements. A low-support bra is not enough. The Bear Grips Padded Sports Bra is a high-support option that lives under a tank or technical tee. Layering matters too: a sports bra plus a Bella+Canvas Performance Workout Tank or a Women's Flowy Scoop Muscle Tank is the standard combo for studio HIIT classes.

Shoes: Cross-Training, Not Running

Pure running shoes have a soft, springy heel built for forward gait. HIIT involves lateral movement, box jumps, lunges, and lifting, so the shoe needs a flatter, more stable platform. Look for a cross-training shoe, a hybrid trainer, or a low-drop training shoe. We do not sell shoes, but the rule from the floor: if your shoe rolls under you on a side lunge or a kettlebell swing, it is the wrong shoe for HIIT.

The Studio Branded Kit Option

If you are part of a regular HIIT studio, the studio often runs its own branded apparel shop where you can buy the studio tee, tank, or hoodie with the studio logo. For studio owners reading this who do not have a merch shop yet: that is exactly what Bear Grips Pro Shops is built for. The studio gets a free branded online store, members order their own gear, the studio earns margin on every order, and there is no inventory to stock at the front desk.

What to Skip

• Cotton tees and tank tops (hold sweat, get heavy).
• Baggy basketball shorts (ride up on jumps).
• Loose graphic tees (snag, distract).
• Slip-on shoes, running flats, or anything with a soft heel.
• Jeans, jorts, anything with a non-stretch waistband.
• Jewelry (chains, dangling earrings, rings on grip movements).

Frequently Asked Questions

Do I need different clothes for HIIT vs. a regular gym workout?

The basics overlap: moisture-wicking top, fitted bottom, supportive shoes. HIIT is more demanding because of the high-impact jumping and the duration of sustained sweat output, so investing in performance fabric and a high-support sports bra pays off faster than for casual strength training.

Can I wear a cotton tee to my first HIIT class?

Yes, but you will not love it. By minute 8 a 100% cotton tee will hold the sweat against your skin and feel heavy. If you only have cotton tees for the first class, that is fine. For class 2 onward, grab a moisture-wicking option.

Are leggings or shorts better for HIIT?

Both work. Leggings are warmer and protect skin during floor work (planks, mountain climbers). Shorts are cooler but exposed skin can stick to the mat. For most studios, members rotate between the two depending on the season.

What does a HIIT studio sell in its branded apparel shop?

The standard studio kit: studio tee, studio tank, studio hoodie, leggings, and a sports bra. Members buy the studio logo gear to wear to class and out of class. Each member purchase generates margin for the studio with zero inventory risk.
