The Heavy Duty Starter Bundle

Casey Viator gained 63 lbs / 28.5 kg of muscle mass in 28 days with only 12 (high-intensity) workouts, each lasting less than 30 minutes. 

Remember that Viator gained 43 lbs / 15.4kg, but Jones conjectured that he lost 18 lbs / 8.1kg of fat, giving him a net lean gain of 64 lbs / 28.5 kg. 

(Jones force-fed Casey Viator each day.)

Jones:

I personally examined this diary and calculated the total daily calories Casey ingested. He never ate more than 5,000 calories, and most days, he ate closer to 4,000, which is minimal considering the brutal workouts he was going through.

This experiment is provided solely to demonstrate what the human body can naturally achieve with a carefully calculated high-calorie intake and high-intensity training.
