I did a quick workout this morning adapted from Matt D’Aquino.
40 seconds jump rope
10 overhead ball slams with twist (10#)
That was a gasser! It did indeed feel like a round of randori, minus the large person trying to throw me to the ground and crush me.
Mr. D’Aquino is a black belt in judo who was also a 2008 Olympian from Australia. He has four excellent sites that are well worth checking out.
