These are ideas, not a program. I wrapped each clip so you know what to look for. If the video uses a cage or a fancy board, the note underneath is how you do it in the grass for nothing.
First 3 steps
You’re watching the first three steps, not a pretty 60. Maximum effort after he’s warm. When the speed drops because of fatigue, he is done.
In the yard. Street, park, or a driveway. Fifteen to twenty yards is enough. You don’t need a track, cones, or a speed school. Count the reps. Stop when he’s slowing down.
Top-end / stride out
Longer sprints. Top-end speed and striding out. Volume builds over weeks. Same rule: when it isn’t fast anymore, the day is over.
In the yard. A quiet street or a park. Forty to sixty yards. One or two days a week is plenty. Don’t turn it into a conditioning test.
