A gym mad new father is fighting off the 'dad bod' by doing adorable home workouts - using his baby son as his WEIGHTS. Kwabena Atuahene, 27, became a dad for the first time in August and wanted to keep up his regular workouts - but had less time thanks to new arrival Zacharyah. The hospital nurse decided to design his own nursery workouts by strapping his son to his chest, on his back and even using the tot as a make-shift dumbbell. Two or three times a week, the he does squats, arm curls, bench presses and press ups - all involving 15lb Zacharyah.
