If you haven’t already, train using the Car deadlift simulator Kalle Beck demonstrates here
I personally prefer having the weight behind me, rather than in front of me, but that means you’ll need to rig up some handles using plumbing pipes. You can see me use them here
I like chasing the squat workout with the car deadlift personally. It’s a great supplemental exercise.
Do you have any stones to train with, or anything to throw?
