@The_Myth, I do a 3x 531 and weighted vest walk for conditioning on non weight days. I finishing every workout w/ loaded carries. Been using kettlebells, like the thicker grip. I try to mix it up since I have 3 sessions, 1 Arm suitcase carries w/ lighter load, standard 2 arm, and then 2 arm w/ unbalanced load (switching half way through). I generally like to get in 100-150 tight paces per set and do 2-3 sets given the day. Really trying to focus on consistent strides and an upright spine.
