Link an attachment handle to a sled via a rope or chain.
Grab the handles and assume a strong lifting position: core and glutes activated, shoulders braced, chest up, knees slightly flexed, and eyes fixed ahead.
Back-peddle till your arms are fully extended (with a slight elbow bend) and the rope/chain is taught.
Make sure your shoulders don't roll forward or traps elevate.
Imagine pinching your shoulders together as you row, pulling your hands to just beyond your midsection. Finish with your bicep parallel to the floor.
Negative excessive lower-body movement.
Step back until the rope/chain is taught and repeat.
*Tips*
Keep the weight lighter for this movement. You want to accumulate volume to maximize the benefits of the sled.
Don't let your back overextend when performing the row. Keep your core braced and spine neutral.
