On a recent Friday morning, a group of about 20 homeless guys warmed up in a parking lot across the street from three shelters in East Harlem. In a circle, they did jumping jacks, twisted their torsos and touched their toes. Fifteen minutes later, they huddled up, chanted the Serenity Prayer ... and took off running. Ryan ... began jogging with the group, known as Back on My Feet, seven months ago. Never a runner, he always wondered what the big deal about it was. Ask him today, however, and hell tell you its so natural, almost spiritual. Back on My Feet is a program that uses running to help the homeless get their lives back on track. In addition to connecting participants with housing and jobs, Back on My Feet is founded on the notion that running can change a persons self-image. Early morning exercise, three days a week, provides an outlet for pent-up emotions and starts to change the way someone thinks about hard work. If the concept seems hokey or contrived, the programs numbers show thats not the case. Back on My Feets program has reached 5,200 homeless individuals. More than 1,900 have obtained employment, and 1,300 have moved into independent housing. Waking up so early every morning - whether the thermometers bubbling over or when its frozen solid - instills discipline and responsibility in the participants. Theyre two valuable concepts, but both are hard to teach in the abstract. They need to be lived to be experienced.
