I showed them a monster walk. Okay, monster walk. Now, we're going to the bottom of the hill, and I want you to lean back into the hill, and we're walking backwards. You're going to align your foot, ankle, knee, and hip, and push through the knee, through the knee, through the knee, backwards, up the hill. Do you know after 30 m, they were absolutely done. Here they are doing all this deadlifting and they don't even have the leg strength endurance to walk backwards 30 meters.
