The Diesel Crew’s Smitty has a deceptively simple training tip for stone work :
Here is a stone training tip guaranteed to help your athletes transition from conventional training means to non-conventional / strongman training.
You will find your athletes who have been trained primarily trained in deadlifts only, have a hard time stabilizing and adjusting to implements that are not fixed, rigid or lifting in close proximity to their own center of gravity.
The solution? Shorten the range of motion. I just finished a workout with one of my wrestlers who couldn’t budge the 160 stone off the ground (at 155 lbs bw), but he can deadlift a lot more than that.
So I lifted the stone on top of one of my tractor tires and had him perform hip extensions for sets of 6-8. This not only conditions his hips and lower back for this position, but also his biceps.
