Individual training for 'speed' skill only

[Toxcatl]

I want to train a player but I only want 'speed' only.
Not working with drill 'sprint' or 'long run'. Give fitness.
Can anyone give a better drill?
I'm out of rest pack now.
I only train him once.
Or maybe those drill work but I only get 'fitness'.
I have to do it again to get 'speed'.
Maybe train him tomorrow after get free rest.

The system works not like you think it works. If you want, you can post here a screenshot of the Skills tab of the player, and I will tell you the most efficient way to train any skill for him. I can't do it without knowing his grey and white skills.
And also levels of your drills. Yeah.
