I was a glider for about 12 years, all time best of 56'. For a variety of reasons, I've started the switch over to rotational.

Any ideas would be great!

I recommend start with going slow and figuring out how to rotate into the power position and finish a throw.  I like starting from that side of it not the other.  I want the finish feeling good then continue to add more to the front end of it.  Kinda idea if you are teaching someone to jump step one is teaching how to land.  

Once I got comfortable with the rotating into the finish.  I would begin doing some South African style throws.  NOT MSA.  So this is foot back at 6 oclock and working through the turn.  Once this feels solid and you can get separation I would try to include the full approach focusing on getting to the middle. 

This is pretty tough to handle in a short post.  But also I watch a ton of videos and try to emulate different things from them that would play well to my strengths.

Hope this helps.  I did a stone breakdown on my blog sometime ago check that out.  May help as well.

I agree with the MSA - I really think it is a technique unto its own rather than an extension of a full rotational throw. I've been doing full SAs from 6:00 with a wide sweep leg. I'm at a point now where I can create some separation in the middle, and I've been getting distances about equal to my glides for the similar weighted shots.

Everything I've been doing up until this point has been at the indoor throwing circle in which I coach, rather than outside on grass. I think I'll start outside this weekend to see how the change in surface affects rhythm and timing. Going to start with HJ spikes rather than cleats.

Chances are high that I'll spend my training time learning to rotate, but until I can produce reliable distances, I'll probably still compete with the glide. Glide seems to be stalled around 50-52' with the stone regardless of how often I train, which will hopefully be enough to keep me near the top end of most Am comps while I make the transition.

If you don't mind me asking, what were your best throws with the glide (Shot, and stone).

Thanks again, much appreciated!

What is your standing throw like?

In general, you have to have a big stand in order to throw far with the glide.
When I was throwing 56' with the glide, my standing put was about 52'. 3'-5' is about what you're going to be able to add with the glide.

If you want to see 10'+ gains from standing to full throws, you'll have to be able to rotate.
I haven't had any luck with the MSA either. I just can't get the lower to upper body separation that is required for a big throw.

The caveat is that 10 weeks is probably not enough time to learn how to rotate, unless you already have a background in discus.

Have you tried a fast step-back? Its much easier to learn and you spend less time in single support than in the full glide.

One of the collegiate throwers I coach switched from the glide to the step back this year and went from 40' to about 44' in one season.
