This instructional video begins Drop Spins from Right Shoulder!
Most likely you will start from Right Flat, but should be flexible to spin from anywhere.
This audio & video is the exercise we use at practice when we break down drop spins by counts.
You will begin by holding each check point for 4 counts, then 2 counts, and then finally do full speed drop spins.
Mrs. Brown also teaches spins in this video. Get a different perspective on learning Drop Spins.
