Sled Conditioning: Zero-Eccentric Load

Zero eccentric work — knees and muscles don't pay for it with pain

Who it’s for

You need high-density conditioning, but your joints can't handle jumping and running.

How it works

Sled pushes and pulls have no eccentric phase—the part responsible for next-day muscle soreness. That means you can run this work frequently and at high volume. Calculate load as a percentage of body weight rather than total plate weight: the threshold where sled work outperforms standard running starts around 21% of body weight, while 50–75% works best for developing acceleration power.

How load increases

15–20 meter sprints, 4–8 minutes rest for heavy work. Pushing is more effective than pulling. Load scales from 20% to 50–75% body weight as capacity improves.

Deload

Every fifth week: light pushes only.
