STRAIV IS FOR PEOPLE WHO ALREADY TRAIN AND WANT TO BREAK THROUGH. You’ve put in the years. You know how to show up. What’s missing isn’t motivation, it’s a system that connects everything you’re already doing and tells you what to change next. Whether you’re chasing a 100 kg bench, a sub-40 minute 10K, or your first pull-up, Straiv is built for one thing: helping you reach specific, measurable goals; not just log another workout. THIS ISN’T A CASUAL TRACKER. Straiv works best if you’re committed to tracking most days: workouts, nutrition, sleep, and honest check-ins with your AI coach. The more complete your data, the sharper Arnold’s guidance becomes. MEET ARNOLD; YOUR AI COACH WITH YOUR FULL CONTEXT Don’t guess. Ask Arnold. He sees your training history, nutrition, recovery, Apple Health data, and goals so advice is about your body, not a generic plan from the internet. • Adjust your program when you plateau • Get nutrition guidance for performance, not crash diets • Understand recovery before you push too hard • Analyze sessions and get clear next steps APPLE WATCH GUIDED RUNS Take structured runs on your wrist with live AI coaching. Follow the plan interval by interval and see plan vs actual when you finish, so you know exactly how the session went. TRAIN WITH PURPOSE • Custom and AI-built workout programs for strength and running • Smart gym logging with progress over time • Running, walking & hiking with GPS and heart rate zones • Post-workout analysis tied to your goals FUEL FOR PERFORMANCE Track macros, calories, and meals with AI food logging plus a full database designed for athletes improving strength and endurance, not just losing weight. SEE IF YOU’RE ACTUALLY IMPROVING Sleep, training, nutrition, and recovery feed into a combined progress view so you can tell whether you’re moving toward your goal or spinning your wheels. THE RESULT Less scattered data. Fewer random programs. More clarity on what to do today to hit the target you set. Fitness isn’t about doing more apps; it’s about reaching the goal you chose.
