Conditioning Programs

Is there a good resource someone here could recommend regarding how to setup conditioning programs for track athletes?

I understand the definitions of intensive/extensive tempo but not sure how to apply them in regards to a 100m sprinter versus a 400m sprinter.

thanks for any suggestions!

Short of researching the various forum threads, CFTS and/or Forum Review are good paths to expand all possibilities with short and/or long sprints!

I think it’s hilarious that a coach actually felt the need to change intensification/accumulation to intensive/extensive. Probably just to make himself feel smart.
