I coulda filmed a better example/video but this should get the point across! SPEED LESSON: RESISTED ACCELERATION
More weight on the sled or more tension on the bands doesn’t always mean better. In fact for the outcome we want to achieve in this scenario it’s worse!
When we use resisted sprints at Southside, the goal is to make the athlete produce more force into the ground without completely changing how they sprint.
If the sled is so heavy that the athlete stands up, starts taking super slow steps, or basically turns the sprint into a march… we’ve gone too heavy.
For most of our acceleration work, I like a load that slows their 10-yard sprint around 10–15%.
One of my biggest cues:
“Same sprint shape — just push longer.”
We want resistance to build better acceleration, not change the movement so much that it doesn’t look like sprinting anymore.
More weight isn’t always more effective. Train the quality you’re trying to improve.
