How to Do the "samurai chop" runner's workout
To do the samurai chop grab a medicine ball with both hands. Put your feet adjacent to each other (keep them very close). Lift the medicine ball up and to the left of your body. Then bring it down and to the right of your body. After this you can do it on the others side, up to the right and down to the left. For beginners 6-10 repetitions recommended for each side and for the more advanced 11-14 repetitions. If this is too easy lift your left food up and then bring your medicine ball up and to the left and then down and to the right. Then you can lift your right leg up bring the medicine ball up to the right and down to the left. This exercise is very good for balance because you are using the up leg to counterbalance your body.
