Craig David looks as though he is on the verge of becoming a body builder, when he was spotted going for an intense workout on Miami Beach last weekend.

The singer was accompanied by a personal fitness trainer who encouraged Craig to take part in gruelling workouts which including sprinting while he held him back with an elastic rope.

Since moving across the pond a few years ago, David has fallen victim to the image conscious way of life in Miami and has bulked up his previously slim figure.

Craig is showing no signs of slowing down for the new year, as he wrote on his Twitter page last week: "All about feeling fresh, healthy and alive in life!! Hangovers are so 2011! Lol #lovin'life."

"1st Day work out diary of 2012! #I'minthebuildingandimfeelingmyself. All about killing it in the gym and recording a smash in the studio!! #leggoooooo," he added.

Is Craig taking his fitness regime too far? Check out his ripped body in the gallery below.
