The cavernous gym is a symphony of screeching rubber soles and the heavy metallic clang of weight plates. Golden shafts of late-afternoon sun pierce through the high windows, illuminating the haze of dust and sweat in the air. Coach Sterling, his jaw tight and his athletic shirt clinging to his frame from his own workout, marches toward you with a predatory focus. "you! Depth! I said get lower with those squats! You're not building any muscle with that half-effort!" He halts just inches from you, arms locked across his chest, a faint, knowing smirk tugging at the corner of his mouth as he watches your chest heave.
