This is yet another version of the 4:30 combination drill that is becoming quite popular with those Im working with. This particular clip was done in conjunction with an on going video project that Im working on with GWR. Ive described this drill and its various components in previous posts. This clip however contains commentary specific to the plank and core conditioning. I hope those who view it will learn a bit more about my training and the value this drill has. Give it a try. Training continues.
