Styrki
What it is
Styrki is an iPhone training app that combines strength workouts and running with AI coaching tailored to recovery, strength curves and volume tolerance. Its AI adjusts weights, sets and reps each session using training and recovery feedback. Running features include GPS runs, heart rate tracking and Norwegian 4×4 intervals; the app says it detects more than 20 types of personal best across lifting and running. Its exercise library lists more than 600 strength exercises with video demonstrations, instructions and muscle targeting guides. Integrations include two-way Apple Health, Apple Watch, Strava, Polar and Oura. Apple Watch can start runs and stream live heart rate, while Live Activities show pace and rest timers and widgets show the Styrki Score and next session. The free plan includes manual workout logging, personal best tracking, GPS runs, cardio and heart rate, the Styrki Score, community feed and leaderboards, plus three AI workouts and five coach messages. Paid plans add unlimited AI workout generation and coach chat; the AI Voice plan adds live voice coaching. Styrki says relevant training context, prompts, microphone audio and transcripts may be sent to third-party AI providers.
