Read full descriptionHide full description
Form8 builds a personal 8-week training program around you β not the other way around. Set up your profile (weight, height, age and goal) and Form8 generates your plan and nutrition targets: - Pick your goal: muscle growth, hybrid or fat loss. - Combine strength with running, swimming and/or cycling. - Train 3 to 7 days per week β sessions are spread smartly for recovery. - Allow combo days: strength plus an easy endurance session on the same day. While you train: - Log reps and weight for every set and check them off. - A 2-minute rest timer starts automatically after each set. - Swap any exercise β squat to leg press, dumbbell to machine β for one week or permanently. - Track per-exercise progress: your heaviest set and volume per week. Nutrition that fits you: - Calorie needs and macros are calculated from your profile. - Separate targets for training and rest days, plus a meal plan that scales with you. - Choose your units: metric (kg, cm) or imperial (lbs, ft). Form8 works fully offline. No account needed β all your data stays private on your own device. Nothing is collected or sent. Start today and build your form in 8 weeks.

Train yourself like you have a coach. Helix is an app for self-coached athletes: AI builds a plan for your goal, workouts go straight to your Apple Watch, and your results, sleep and heart data sync from Apple Health on their own. One picture of your load: running, cycling, swimming, strength, HYROX. WHAT YOU GET β’ An AI plan for your goal. A 4-week plan built around your race, HYROX event or hybrid goal and your schedule. Generated in a minute β then make it yours. β’ One load score. A single load scale across every activity type, including strength work. Actuals close themselves from Apple Health (Strava connects too) β so you finally see how hard you really trained this week. β’ Fitness and fatigue. ATL, CTL and readiness show whether you're building form or digging a hole. Readiness accounts for sleep, resting heart rate and HRV from Apple Health. In plain language, not a chart you have to decode. β’ An AI assistant. Ask βwhy is my readiness 54?β or have it swap tomorrow's run for an indoor ride. The assistant knows your data and proposes every change as a before β after card β you apply it. YOUR PHONE AND WATCH DO THE ROUTINE FOR YOU β’ Apple Health syncs itself: type, time, distance, heart rate β and your morning data feeds straight into readiness. β’ Plans go to Apple Watch: intervals, alerts for your heart-rate zones, strength steps β in the native Workout app, no separate watch app needed. β’ Notifications that matter: your plan in the morning, your result logged after the workout. β’ All your analytics in your pocket: ATL/CTL, readiness, plan vs actual, weekly volume. Requires iOS 17+. Privacy policy: https://helixtraining.ai/en/privacy
