Describe offsets.

I do Farmers every week. great exercise... probably not nearly as taxing to the core as yoke walks. Yoke walks should be easily replicated if you have a home gym. Some chain, a normal olympic bar... if you want to be very high tech you can buy loading pins, but it wouldn't be necessary to the setup at the most basic levels. The benefits of using the more ghetto setup is that the chains will allow the weight to move in all directions, forcing you to stabilize every which a way as you walk. A more traditional yoke setup that strongmen use has the entire frame as one piece... it is a little more forgiving.

The other very interesting tool that I have become a fan of is the "pillar of pain" or a pvc pipe filled 1/2-3/4 with water. The pipe needs to be a full length... I think that is 9-10ft. Depending on the size of the pipe you may end up with anywhere from 40-90lbs of water weight. The deviousness is that the water weight will quickly shift from one side to the other, putting nearly all 40-90lbs loaded to the right or left depending on how you walk and compensate. Try overhead walks or even simple overhead presses for extra fun.
