Start a clock and flip a tire once. Rest the balance of the minute. At the start of the 2nd minute flip the tire twice. Rest the balance. On the 3rd minute flip the tire 3x. Continue this process until you can't finish the set in 1 minute. Recommended tire weight is 3x body weight.
When you fail the work inside of a minute, rest 5 minutes and repeat.
Post total flips to comments along with the weight of the tire.
