I have a few friends that practice Sonnon's stuff which looks great from what I've seen. I have not personally tried it more than just playing along with my friends.

a very good move i do daily is breath in with you arms stretching out on the side of your body, you have to see every movement of your arms, togetcher with the breathing, breath out, push the hands down and lift one foot up, end the move and do it other way around.

this increase your sight, your together movement in balance to catch his kick, and step on his knee, i have a lot of this kind of movements i train from a pencak guru aka my dad when i was kicked out the house when i was young.

traditional movements but surprisely effective sometimes
