Run-up Leg-spin - wrist spin
Leg Spin basics - Consistent and repeatable action - the run-up
No-one ever showed me how to run-up to the crease and bowl, I just worked out a way of doing it as a kid, so when I returned to cricket much later in life, I just reverted to the way I did it at school. For the last 8 years or so I’ve worked on it a little with some guidance from people on the internet and as a result modified it a bit, but I’ve always been aware that it’s not that good and it's massively inconsistent changing in games and during the season and I’ve never been able to figure out how to go about improving it.
This year at the start of the season I bowled fairly successfully off of a slightly longer run-up than usual. This happened after some feedback from a good wicket keeper I played with for a month or so, and as a result I took a decent amount of wickets. I then injured myself and went back to shorter run-ups for the rest of the season while my Achilles tendon healed.
Towards the end of the season I watched a SKY TV master-class featuring Glenn McGrath which has since been removed. In this master-class, he explained how important the run-up is, but went further in that he explained how he established his run-up and this resonated with me, because I’ve never heard anyone explain how you might go about establishing a run-up. This is basically what he said as far as I can recall and it’s pretty straight forward...
Keep an eye out for the video as it may reappear someday.
In the meantime despite the fact that this is a seam bowlers run-up - the basic premise relating to setting off on the correct and consistent foot and maintaining a smooth approach is all relevant and worth having a look at, as to is Stuart MacGills video.

This Youtube channel also has some good basic stuff about aspects of bowling albeit aimed at fast bowlers, but the principles are pretty much the same and are worth looking at https://www.youtube.com/watch?v=4YUDKUooHeg - The gather
