Austin played coach for the day at H.S. Thompson Elementary School in Dallas, encouraged students to eat right and get at least 60 minutes of exercise a day while having some friendly competition with the children.
Austin got active, jump-roping, running football relays and even hula hooping with the kids.
"I remember going with my buddy. We used to wake up at 7 o'clock in the morning and play for six hours a day," said Austin.
And kids got the message.
"If we don't exercise, we're going to be lazy," said fifth grader Alex Arriaga.
"I like seeing Miles Austin because he's entertained me since I was a little kid," said fifth grader Travion Sampson.
"You know, see them, play with them. It kind of makes you feel young again," said Austin of the children.
Verizon Wireless sponsored Tuesday's event and the company is going to North Texas schools every Tuesday until the Super Bowl. Verizon is donating fitness equipment and $1,000 to each of the 15 schools.
