Santana Moss pushed a blocking sled downfield, alongside four middle school students.

Later, Moss cheered on the students as they ran the 40-yard dash on the club's synthetic turf field at Redskins Park.

It was part of the Redskins Charitable Foundation's "1st Down for Fitness" program. Moss and 14 other players were on hand to encourage the students to stay physically fit throughout their entire lives.

More than 100 middle school students from Pyle Middle School in Montgomery County and Seneca Ridge and Sterling in Loudoun County attended the event.

The program included five activity stations where the team's strength and conditioning coaches spoke to kids about the important of staying active to keep their hearts healthy.

In addition, NFL Films was on hand to tape a national Live United public service announcement featuring Moss.

The event also allowed the Redskins to honor Matt Markel, a student at Pyle Middle School who helped raise more than $20,000 for cardiac research.

Through a bracelet he developed as a fund-raiser, Markel raised $2,500 to donate to the Larry King Cardiac Foundation.

Officials from the Redskins Charitable Foundation, Moss and Larry King, Jr. were on hand to accept the check and commend Markel for getting involved in an important health and wellness campaign.

Other Redskins on hand for the event included Rocky McIntosh, Rock Cartwright, Lorenzo Alexander, Leigh Torrence, Chris Wilson and Colt Brennan.
