Train with set-by-set guidance and a Coach who adapts your plan through conversation and how you train. MADE FOR IPHONE DUO Open Duo to see Coach beside your schedule, workout details beside your calendar, and activity history beside your results. Fold or unfold during a workout without losing your current set, rest timer, or unsaved edits. A COACH THAT LISTENS Ask for a plan, get feedback on a meal photo, or adjust your week. Coach replies with interactive exercise cards, workout plans, progress charts, and proposed workout changes, right in the conversation. GUIDED WORKOUT TRACKING Follow each set with target weights, set history, and animated form guides. Rest starts automatically between sets. Track your session from the Lock Screen and Dynamic Island, or open Coach and return to your workout in one tap. MORE WORKOUT. LESS PHONE. Start today's workout from Apple Watch.

Apply changes to one set or matching remaining sets, then save. When you add an exercise mid-workout, SensAI automatically uses your previous measurements or estimates a starting point if it's new to you.
