I'm in the process of re-designing my hurdle warm-up and I've used your recommendations for the sprint w-u from the gpp disc in the past.
Though I'm still using that template, I want to make sure I've got the components sequenced properly.
Where would (if you would) incorporate any hurdle drills into the w-u would they take place in the Mach drill section, possibly between the runs of the 2-4 x 30m part of w-u two or where exactly?
Would it be advisable to do the flat sprint w-u section of the w-u, as above, and then follow that up with actual hurdle starts over h1/h2 etc.?
