"A.I" wannabe Michael Johns may be a singing stud - but he doesn't work out like one! TMZ tracked down a tune written by L.A. fitness guru Barry Jay that Johns recorded about a year ago.

But after laying down the track, the "A.I" wannabe tried his hand at Barry's Bootcamp in West Hollywood, where regulars include Jake Gyllenhaal, Teri Hatcher, and Nicollette Sheridan. But when it came to the fitness ass-kicking, according to Barry, the Aussie just laid down -- and couldn't keep up with the workout.

Wait 'til Simon finds out about this.
