hi guys, going through certification and i dont know why i am so stumped on variations and how to put them into a sequence. we were told variations need to be at least one minute. can you do two 30 second variations back to back? for example, 30 sec hold, into 30 second pulses? i think i am overthinking this lol. can someone give me an example of a move involving variations
