Practice your secondary weapon (I worked with my cane) for at least 10 minutes, making sure that you spend at least 1/3 of that time practicing with your off hand. Then get out an ordinary automobile tire and set a timer for 12 minutes. Complete as many sets as you can before the timer beeps of 10 each: Tire Push-ups, Tire Squat Presses, and Tire V-ups.
