Perfect Rep Timing, Every Time

Smart Tempo Control
Choose from proven preset tempos (Hypertrophy, Strength, Explosive) used by elite trainers, or create custom tempos tailored to your specific training goals. Select concentric-first timing for squats, deadlifts, and presses, or eccentric-first timing for pull-ups, rows, and curls. CENTRIC adapts to your methodology and exercise selection.
