New York, Dec 8 : It looks like Hollywood actor David Duchovny is finding new ways to channel his ‘excess energy’.

Duchovny, estranged husband of Tea Leoni, was recently spotted at Robert Pennino''s indoor triathlon training class at Equinox on the Upper East Side.

"He missed this summer''s Malibu Triathlon because he was in sex rehab," the New York Post quoted a source, as saying.

Recently, Duchovny and Leoni sparked rumours of a reconciliation.

The couple had declared their separation, a week after the actor checked out of the rehab where he was treated for sex addiction.

The pair had been separated "for several months", but opted to keep the news private for the sake of their two kids, Madelaine, nine, and Kyd, six, according to a statement from their representatives.

The reports of reconciliation caught fire when the couple was spotted celebrating Halloween together in New York. (ANI)
