Here is a new video from Spain showing how versatile the Powerbreather is and how it can quickly take your training program into the Fastlane. Use it in combination with EndlessPools to work on your technique then go outdoors and explore the open ocean swimming lanes at Vies Braves in Costa Brava.
Make sure you get the new Easy breathe Speed Vents which now come as standard with every Powerbreather too. They make it so much easier for everyone to enjoy swimming again, and also to benefit right from the start. The Easy Speed Vents provide a very mild level of hypoxic training, but you can upgrade when ready to Medium and Power resistance levels, simply by changing your Speed Vents!
