What should I wear for HIIT training?
· DAMIAN ALLEN
High-intensity interval training (HIIT) is one of the most effective workouts for burning calories, building fitness, and improving cardiovascular health. But wearing the wrong kit can hold you back. Here's everything you need to know about choosing the right activewear for HIIT training in the UK.
What should I wear for HIIT training?
For HIIT workouts, you need activewear that handles explosive movements, high sweat output, and rapid direction changes. The essentials are: high-waisted squat-proof leggings, a high-support sports bra, a moisture-wicking top, and cross-training shoes with a flat, stable sole. Avoid loose or baggy clothing — it can restrict movement and get caught during exercises like burpees and box jumps.
What are the best leggings for HIIT?
The best leggings for HIIT are high-waisted, squat-proof, and made from a nylon-spandex or polyester-spandex blend with four-way stretch. Key features to look for:
- Squat-proof fabric — remains opaque during deep squats and lunges
- High waistband — stays in place during burpees, box jumps, and jumping jacks
- Moisture-wicking — pulls sweat away from the skin to keep you dry during intense intervals
- Four-way stretch — allows full range of movement in all directions
Our Seamless Leggings UK for Women and CHRLEISURE High Waist Pocket Leggings are both built for high-intensity training — squat-proof, four-way stretch, and moisture-wicking. Browse the full High-Impact HIIT Essentials collection for more options.
What sports bra is best for high-impact HIIT?
For HIIT, you need a medium to high-support sports bra. Look for encapsulation or compression support, a wide underband for stability, and a racerback design for full shoulder mobility during overhead movements like thrusters and burpees. Moisture-wicking fabric is essential for managing sweat during intense intervals.
Our Millennia Breathable Halter Neck Sports Bra and ButterSoft X Back Sports Bra are designed for high-impact sessions — supportive, breathable, and built to move with you.
What shoes should I wear for HIIT workouts?
Cross-training shoes are the best choice for HIIT — not running shoes. Cross-trainers have a flatter, more stable sole that provides lateral support during side-to-side movements, and enough cushioning for jumping and landing. Running shoes have an elevated heel and soft midsole that reduce stability during lateral and rotational movements common in HIIT.
Can I wear a gym set for HIIT training?
Yes — a matching gym set (leggings and sports bra) is ideal for HIIT. Look for sets made from performance fabrics with four-way stretch, squat-proof construction, and moisture-wicking properties. Our Summer Seamless Fitness Set and 2-Piece Push-Up Yoga Bra & High Waist Leggings Set are popular choices for HIIT — available in multiple colours and sizes S to 3XL. Browse the full Fitness Gym Sets collection for all options.
How do I choose the right size for HIIT activewear?
For HIIT, fit is important — too loose and clothing can get in the way; too tight and it restricts movement. Use the size guides on each product page, which include bust, waist, and hip measurements in inches. If you're between sizes, size up for leggings and true-to-size for sports bras. Our UK-based team is available via email or WhatsApp if you need sizing advice.
