Stuart Phillips, PhD, is a professor of kinesiology and the director of the Physical Activity Centre of Excellence at McMaster University. His research focuses on the roles of exercise and nutrition in regulating human skeletal muscle protein turnover and body composition, particularly during aging. His published work investigates resistance training protocols, muscle hypertrophy mechanisms, dietary protein requirements, and physical function recovery.

The human body is approximately 70% water by content, with most of that water contained within cells and skeletal muscle mass.

"So I think most people will probably understand we're about almost 70% by content water, and most of that water is inside our cells, and a lot of is inside muscle mass." (said at 0:02:07)

Total body water in healthy adults typically ranges from 50% to 60% of total body weight (averaging approximately 60% in adult males and 50–55% in adult females, though fat-free/lean mass itself is approximately 73% water). The claim is accurate that the majority of body water resides intracellularly (intracellular water comprises roughly two-thirds or ~60–65% of total body water) and that skeletal muscle tissue represents the largest reservoir of this fluid.
