Corey Scott grips a truck tire with both hands and stands with his back to a brick wall. He lifts the tire while rotating his upper body and slams it against the wall over his left shoulder.
Up. Bang. Down. Bang. And again. And again.
"It's grueling," he says.
Scott, 39, is a fitness trainer who grew up on a farm near Plainville, a really honest name for a burg in northwest Kansas. But his agricultural origins only partly explain this tire thing. It's not as if he and his buddies used to swing, toss and flip tires back home.
Which is exactly what's going on here, in a field near Bishop Miege High School in Roeland Park, Kan. A few friends meet once or twice a week for a "functional strength" workout that makes interesting use of Scott's tire collection, which includes a 300-pounder.
Squatting, turning, throwing, lifting, swinging, jumping: These are "total body" exercises long favored by athletes and pushed in recent years by fitness experts as better conditioning overall than simple weight machine workouts.
With better conditioning, people can gain the strength and resiliency they need to get through their day with more ease of movement and without undue fatigue and joint and body pain, he said.
Messing around with tires is a rigorous way to get there: One by one on a recent Wednesday evening, Scott and several others squatted and lifted the biggest tire, the 300-pound one, flipped it over, then hopped into and out of the center of it.
A few feet away, two others had picked up sledgehammers and were alternately swinging them over their heads and battering another tire, which lay defenseless on the ground. One fellow had attached straps to a large tire and, moving backward, bent his legs and pulled the tire along the ground.
It was about a year and a half ago that Scott, who lives in Prairie Village, Kan., was back at the family farm when he noticed a giant tire in a neighbor's frozen pasture. His plan to develop a tire workout had been bouncing around in his head, and here was Exhibit 1.
Scott tried to explain to the neighboring farmer his exercise idea — the man was perplexed — and asked to buy his tire. The farmer said the old tire was no use to him and used his tractor to help load it into Scott's F150. He charged $10 for the trouble.
Although Scott doesn't exactly direct the tire workouts, he doesn't mind being a motivator. Well into a recent 90-minute session, he noticed the collective energy was flagging.
"We're slowing down," he called out. "Keep moving."
"Corey, I'm done," said Frank Reardon, a 21-year-old accounting student.
"You've got another half-hour in you," Scott said. "You know, some of you were late."
John Plute, a 39-year-old database administrator and father of three from Kansas City, said the tire workout was a fresh alternative to the gym, which he has never really enjoyed. But he knows his limits.
"I don't go anywhere near that big tire," he said.
For now this is a gathering of workout friends and not a formal exercise class, but Scott is considering a tire class. A high school wrestler and former wrestling coach, he said "total body " or " functional " exercises improve the body's large muscle groups rather than focusing on isolated muscles. They also "confuse" and thus challenge the muscles more. And they burn a lot of calories, he said.
"And working isolated muscles is just not the way life is," he said.
In technical lingo, the body is made to function in three planes: sagittal, frontal and transverse. Or put another way: forward/backward, side to side and rotating. Many weight machines and free weight workouts and, of course, walking and running, are performed mostly "straight ahead."
Trainers are incorporating more functional workouts at gyms and health clubs, although traditional machines, treadmills and stationary bikes still take up much of the floor space. Trainers also offer total body regimens at indoor and outdoor "boot camp" classes.
Exercise tools, such as stability balls, can integrate rotating, jumping and body-stabilizing moves into workouts.
