POWERbreathe K5 – Advanced Inspiratory Muscle Trainer for Elite Performance
Elite-level inspiratory muscle training with real-time biofeedback.
The POWERbreathe K5 is the most advanced device in the POWERbreathe range, built for elite athletes, coaches and sports professionals who want precision resistance training and in-depth performance analysis. It uses a patented electronic tapered-resistance system that adjusts dynamically throughout each breath, and connects to Breathe-Link® software (desktop or laptop, not an app) for live biofeedback and detailed session analysis.
Whether you're training for competitive sport, endurance or high-performance recovery, the K5 gives you the data and customisation to fine-tune your training.
How It Works
Each breath through the K5 is met with electronically tapered resistance that adjusts automatically to match the natural decline in force through your breath, allowing for fuller lung volume and more complete training breaths than a fixed-resistance device. Connect to Breathe-Link® software for real-time biofeedback, custom training programs and detailed session history.

Care and Cleaning
Remove the mouthpiece and valve head after each session and rinse in warm water, opening and closing the valve under the tap to clean the surfaces. Shake off excess water and leave to air dry. Once a week, soak the valve head in warm water with a cleansing tablet for around 10 minutes instead of a plain water rinse, then rinse and air dry. Keep the electronic display unit itself dry — only the mouthpiece and valve head should be rinsed or soaked.
Important Notes
Don't use the K5 while you have a cold, sinus infection or chest infection — wait until you're fully better. Training should never hurt — if it does, stop and see your doctor. Adult supervision is recommended for anyone under 16.
