For some retired players, staying fit means to do freely what they liked anyway. In Frankie Hejduk's case, that was surfing.
Others take up a new athletic pursuit. David Beckham has gotten into SoulCycle.
Thomas Dooley is a soccer tennis devotee, and he's gotten other former pros into regular matches and competition as well.
Keeping fit is important for everyone, though, not just former athletes. I'm going to give different fitness programs a try and report here which I personally find most effective and would recommend, not just for soccer players, but anybody.
First up is capoeira. LD's own teammate, Juninho, practices the Brazilian martial art.
One of the capoeiristas featured in the video here is giving a free class in Glendale at Jewel City Yoga tomorrow at noon, so I'm going to check that out.
