“While Derek Jeter and the Yankees have kept fans' heart rates up all season long -- particularly over the team's current six-game winning streak -- Jeter took some time yesterday morning to increase the heart rates of several children who participate in his "Turn 2" foundation, which helps children attain healthy lifestyles as well as promotes academic achievement. Several high school students were chosen to participate in a light exercise session at the 24 Hour Fitness-Derek Jeter Gym in Midtown, which recently opened. Jeter watched as the students did jumping jacks, pushups and other exercises with help from a trainer. It is the second such gym Jeter has opened, with another one set to open in the fall. ‘One reason why I decided to do this is because helping the kids is something that means a lot to me, and I want to share that with everybody,’ Jeter said. ‘You don't have to be a professional athlete to keep yourself in great shape.’ With the black steroid cloud hanging over major league baseball, including the recent suspension of Manny Ramirez and admission by Alex Rodriguez that he used performance enhancers, Jeter stressed how important it is for kids to stay healthy the right way. ‘Our foundation throughout the years has preached prevention of drugs and alcohol to promote a healthy lifestyle,’ said Jeter. ‘This is a part of it --staying in shape, working out and exercising helps your health and makes you feel good about yourself. It is one of the main reasons I wanted kids to get an opportunity to do that today."
