Hello people
This is a video from the breathing mechanics section. You will see at minute 10.00 there is an advanced progression of the exercise where the goal is to get to a 16 second inhale and a 18 second exhale.
You simply start with a 6 second inhale and 8 second exhale using the breathing pacer app to programme the numbers. Move through the progressions at your own pace until you can perform a 16 second inhale and 18 second exhale. This may take several weeks (maybe even longer) and that's all good. Performing the other breathing mechanics exercises (daily) will help you achieve this. Remember, 10-15 minutes a day of breathing machines work will go a long way to achieving this. The added benefit of doing this daily is that you train consistency and discipline which are both very important mental skills.
Why do you want to achieve this? When it comes time to apply the breathing mechanics work to the dynamic breathing training section of the course you will need to have really good rate and depth control. By working on your inhale and exhale capacity you will see that you will be far better equipped to control the rate and depth of your breathing during physical exertion PLUS it will allow you to control you breathing to recover faster.
Toward the end of the exhale it is totally fine to fill the upper chest with air - in-fact that's exactly what you want to do. Start low and move up toward the end of the inhale. Let us know how you go with this.
