You hear a lot about "posterior chain work" (training everything behind you such as glutes, hamstrings, traps, etc) and there are a multitude of ways to put it into practice.
One way is the reverse sled pull. In the video above, I work my "posterior chain" by:
- Dropping my hips low
- Pulling sled towards me by engaging my lats
- Standing up, taking two steps backwards, then dropping low and repeating.
It's a REAL BURN, and you add another dimension to it by PUSH the sled a desired length, then pulling it back. OUCH!
