Classic Physique Ultra Briefs
Minimum 1” side — Maximum impact
Inspired by the iconic CBUM-style trunk, the Muscle Potential Ultra Brief is made for athletes who want to turn heads and showcase more of their physique—without sacrificing stage standards.
Featuring a bold, tapered cut with a minimum 1” side strap, this style is all about sharper lines and deeper detail. Choose your preferred rear coverage—Full, ¾, ½, or ¼—to control just how much glute you show.
You’ll provide your waistband, front, and rear height measurements, and we’ll tailor your suit for the ultimate fit. To preserve the signature Ultra shape, we may make small adjustments for symmetry and structure.
Each suit is finished with our signature Muscle Potential brand tag, because bold trunks deserve bold branding.
Built for competitors pushing the edge of Classic Physique, the Ultra Brief is designed to highlight your best assets—front, back, and every angle in between.
Muscle Potential is not your typical classic physique briefs.
