Nice Matt Holborn violin lesson on warming up with scales and chords

Will check out Matt's other Jazz Violin Advice videos

Stepping Exercise and good video showing fundamental Suit training

 From a Mike Sigman post:

As in all the Chinese martial-arts, you should constantly keep your weight and the weight of anything you hold or lift in the sole of your foot/feet ... without ever letting the forces rise above the soles of your foot/feet. If you're just standing, always allow your complete weight to rest in the soles of your feet. If you're holding something, feel the weight of that something always resting in the soles of your feet. If you lift a leg for a step, feel the rising leg's weight rest in the sole of the other foot. And so on. If someone put their hand on your rising leg, they should feel the sole of the grounded foot.

As you lower the raised foot, let your weight first sink into the grounded foot, going into the other foot only when it is positioned properly.

...another forward and backward stepping exercise that is taken from the Oblique Walk and the Step Back Whirl Arms (Repulse Monkey) of the Laojia Yilu. I'll put a brief clip of Zhu Tiancai showing the movements from the form; mine look slightly different, but it's the same natural winding of the body. The idea is to do the stepping while including the whole-body winding and unwinding (Open and Close) as it moves.

When you're moving forward, as an example, think of your molecules as all moving forward as one group, but imagine/feel that there are elastic spider webs attached to each molecule, slightly resisting your forward movement. Same idea as imagining moving through water, more or less, but I like this particular visualization sometimes.

And here is a good video showing good exercises for training Suit fundamentals:
