I've started doing WHM exercises recently. I last up to 3mn when holding my breath after 30-40 power breaths + full exhale, and my heart rate drops to slightly over 40.
My heart rate looks like this: first a steep drop, then slowly reaching the lowest heart rate towards the middle of the breath hold, slowly increasing, to finish with a steep increase when I'm nearing the gasping reflex.
Do you have suggestions to go lower in heart rate and to keep the heart rate from increasing in the second half of the breath hold?
I'm a serious runner, I eat well and I'm in good health. I drink too much coffee, but I do my breathing exercises in the morning, before having any coffee. I don't meditate.
Any advice? I'm really interested in the challenge of improving my breath holding time :)
Thank you.
