Generally speaking, physical/breathing exercises are going to increase the flow of energy. You can add visualization/focusing on the chakras while doing the exercises.
A week or so ago I saw large dog sitting in the back of someones truck super chill (not sure of the breed), maybe 180lbs. Was thinking I bet that dog barely works out yet it could throw me around. Then I notice he was doing that rapid panting breath dogs do and it reminded me of breath of fire. My thought was I wonder if that how dogs stay in shape when they don't get enough exercise. I did a very shallow but rapid breath from the solar plexus while walking home (trying to stay over 90 breaths a minute). While walking home mid speed trying not look too suspicious. It felt like jogging. Was planning to test it out more because seemed to work on a similar level as hypopressure (hypopressive?) and it hit the pelvic to solar plexus area nicely.
For some reason I forgot to try again, thanks for posting this indirect reminder. A person can always take a few full breaths if they are struggling vs running where you can't catch your breath making it interesting. Might have to go for a walk now. It takes a lot of focus to do making it meditative and should help with kundalini. Need to test this method out.
