CPK delivers an intensive upper body builder workout designed to build muscle, increase strength, and incorporate core stability with posture correction. This three-circuit workout progressively overloads all upper body muscles including chest, back, shoulders, arms, and core through compound and isolation movements. Each circuit repeats twice before advancing, maximizing muscle fatigue and growth while maintaining proper form and breathing techniques. Equipment needed: - Two pairs of dumbbells (one heavier, one lighter) OR one moderately light pair - Exercise mat
