Technique
Top Triangle
A full-lungs hold sandwiched between a full inhale and a controlled exhale to neutral. Effects vary person to person — some feel energized, some feel relaxed.
How
With a neutral spine and a full breath wave: inhale for 4s → hold with full lungs for 4s → exhale for 4s to neutral. Repeat for about 2 minutes. A bigger version extends the hold to 4-8-4.
