In this short video, fitness creator Eric Roberts outlines seven unconventional physiological cues that may indicate muscle growth. He explains that increased thirst, muscle twitches, tighter clothing on muscular areas (with looser fit around the waist), constant hunger, feeling hotter, a rising scale weight despite more definition, and a greater need for naps are all signs of the body adapting to new muscle tissue. Roberts ties each sign to underlying mechanisms—muscle water content, nervous system adaptation, body composition changes, higher caloric demand, increased metabolic heat, water and glycogen storage in muscle, and the necessity of sleep for recovery. He concludes with a call‑to‑action, inviting viewers to click the link in his bio for a free workout program.
