In high-intensity training, performance often comes down to small margins.
As you tire, even seemingly trivial things – like having to adjust your clothing due to chafing, overheating, or a poor fit – can break your focus and interrupt how you work out.
Our point? That in training, activewear plays a much bigger role than most people realize.
That’s why, between moisture-wicking fabrics and breathable workout clothes, F45 athletes are choosing training gear designed to help them manage sweat, regulate temperature, and stay light as they move. And now, thanks to the F45 Training | Reebok collection, so can you. Featuring T-shirts, tank tops, hoodies, and coming soon training shoes purpose-built for F45, this brand-new line of street-to-studio apparel is engineered for the physical demands of a challenging HIIT workout – and designed for wherever your day takes you next.
But what makes performance activewear effective? From fit and breathability to sweat resistance and support, we break down the features and fabrics behind what your training gear is actually doing – and how it can help you smash your next F45 workout.
What is performance activewear – and why does it matter?
Performance activewear is built for high-intensity exercise. We’re focused on breathable workout clothes that allow airflow and hold their shape during movement. Because when it doesn’t? You notice.
You don’t think about your clothing when it’s working – but the second it isn’t, it’s often all you can think about. When fabric holds onto sweat, it clings to your skin, causing chafing and irritation. As it moves, you find yourself adjusting it mid-set: interrupting a deadlift or dropping the battle ropes because you’re suddenly uncomfortable in your own gear.
That’s what the wrong performance activewear looks like. How about the right gear?
Key features of high-performance training gear
Below, we break down what to look for in performance activewear, and how our brand-new collaborative line of apparel – the F45 Training | Reebok collection, which you can shop now – gives you everything you need for a cooler, more comfortable workout.
Moisture-wicking fabrics
Moisture-wicking fabric pulls sweat away from your skin and moves it to the outside of the fabric, where it can dry faster. This stops sweat from sitting on your skin and keeps the fabric from sticking to you as your workout gets more intense.
Want to experience it for yourself? The Reebok | F45 Training T-shirt uses RBK-DRY moisture-wicking fabric to draw sweat away from your body and spread it across the fabric surface, creating a weightless feel on your skin and giving you more freedom to move.
Breathable workout clothes
Breathable workout clothes allow air to move through the fabric, helping your body release heat as your temperature climbs.
One example? Polyester, which is lightweight and built with an open structure that keeps air circulating. This helps sweat dry faster and helps prevent odors from building up.
The F45 Training | Reebok Tank Top is made with 92% recycled polyester to support airflow, helping you stay cooler and maintain output during high-intensity work. Better still, its snug fit helps minimize distractions and help you focus on what really matters – the workout!
Fit and support
When clothing is too loose, it shifts and creates friction. When it’s too tight, it can limit how you move – and make each rep feel harder than it should.
That’s why the right fit enables your performance activewear to sit comfortably on your body, without having to constantly adjust it during strength training or HRV (heart rate variability) training. As a feature, fit and support are particularly vital during fast transitions and lifts, where small disruptions can affect your form and increase your risk of injury.
Grab–and–go layers
Having a layer to wear to and from training removes a small point of friction from your fitness routine. An easy, breathable layer to put on or take off as your body warms up and cools down is a must-have in the winter months!
Make the F45 | Reebok Training Relaxed Hoodie your first port of call when it comes to post-workout recovery. Made with a blend of comfortable cotton and polyester brush-back fleece, it retains warmth while staying light – staving off the chill in the air while still allowing airflow. The kangaroo pocket and drawcord-adjustable hood keep your hands (and head!) out of the wind, while the fit is relaxed: with extra room in the body, chest, and shoulders.
Pull-on not your style? The F45 | Reebok Training Relaxed Zip Hoodie can be worn closed or open over your training gear for even more options.
Supportive footwear
Shoes are a critical part of high-performance activewear because your feet absorb the impact of every movement – particularly in a challenging F45 workout. Every jump, landing, and change in direction sends force through your body from the ground up, so it’s crucial that your shoes provide the grip and cushioning to handle that constant load.
That’s why we collaborated with Reebok on the next phase in the evolution of HIIT footwear: the Reebok Nano X5 Edge.
Built for the constant transitions of HIIT, the shoe’s FlexWeave upper delivers a rare balance of breathability, flexibility, and structure – adapting to your foot as you move while maintaining the support you need through explosive efforts. Underfoot, a zoned DualResponse EVA midsole is softer and more responsive in the forefoot for jumps and sprints, and firmer in the heel to create a stable base for lifting.

Choosing the right training gear for your workout
As F45 athlete and trainer Jordi Duff explains, “Every F45 workout – whether it’s cardio, resistance, hybrid, or recovery – asks something different of your body. So, it’s essential to arrive wearing something that supports your movement and feels comfortable as you train.”
Read on to match the right performance activewear to your next workout at F45.
Training gear for cardio workouts
Our cardio workouts use short intervals with minimal rest to keep your heart rate elevated. Movements such as running, rowing, and jumping provide valuable aerobic exercise: improving your running endurance and boosting your cardiovascular fitness.
In these workouts, your body produces heat quickly – which means sweat. That’s why you’ll need to prioritize breathable workout clothes that allow heat to escape, and moisture-wicking fabric to prevent overheating and stop the fabric from feeling heavy.
Training gear for resistance workouts
Resistance workouts focus on controlled strength using weights – and slower movement patterns like progressive overload – to build lean muscle and total-body power.
During these sessions, your workout clothes need to move with your body – rather than restricting range or slipping out of place during lifts. Here, opt for snug-fitting, correctly sized performance activewear with flexible materials that don’t interfere with your form.
Training gear for hybrid workouts
Hybrid workouts combine cardio and resistance with short transition windows: fusing strength, core, and agility movements into a single session.
In hybrid sessions, your body will move between a high heart rate and controlled strength work – so your gear needs to handle both. Choose breathable workout clothes to manage the heat, flexible materials to enable a wide range of movement, and moisture-wicking fabric to avoid leaving the workout soaked in your own sweat!
