At 5’9″, 192 lbs., Musclemania® Physique Pro Duke Nduka has gained 12 lbs. of muscle over the past 18 months. The California engineer says, “My training and diet doesn’t change that much throughout the year. I eat and train to stay lean and show ready year round. I am able to achieve that using carb cycling. I eat low carbs 3 days in a row and a day of high carbs.”
