Using a light dumbell such as 4 kg, start to move it forward and backwards so you feel the momentoum. Now try to move your hand with more awareness to each finger, each angle and so on so you move as one unit and are ahead of the torque. This rather weird drill came to me in an erobic/dance class I am taking. They use dumbells to do balistic arm work and it was new to me. At the beginning I felt the strain in my joints and muscles and after a while I thought of this and from then on it felt fine. I am not a fan of this type of movement, I like the dance part but being cut doesn’t interest me much. Lessons come in all forms if you have an open mind and I hope to have one one day 🙂 If you are breathing there is hope.
