I hate some of the new modern training ideas. They are so dangerous and lame. The rolling rubber ball is so annoying. That peice of garbage belongs on a nice sandy beach. All these so called personal trainers need to go. Half of them are about 17 years old and have no experiance. Walking dumbell lunges accross the gym. These knuckleheads need to take that nonscense outside or behind the gym. I know Coleman does lunges but you dont see him waltzing around the inside of the gym. I see all these personal trainers having these house wives rolling around on a rubber ball and waltzing around the gym with a pair of little dinky dumbells. I also get a kick out of the people, who do their aerobic activity before they lift wieghts.? Then I see these Roided up morons yapping on their cell phones while walking on the treadmill or during the middle of a workout.? .... I think its time to put the toys away, load up a bar with some steel. shut your pie hole, and focus on building some quality home spun, natural mass.
