Flip a tire and then jump into the center. As soon as you land inside the center of the tire immediately jump out of the tire to the other side. Turn around and repeat. 3 rounds of 2 minute of max reps followed by 3 minutes of rest.
Here is a video of the jump thru. These gents need to get to our seminar...they'd cut their time by half with more efficient flips.
Post tire weight and total reps combined to comments.
