You walk into the gym and think: what do I actually lift today? Eureka Strength answers that, every session, for adults over 60 who want to get stronger without guessing — and without following programs written for 25-year-olds. Built by someone who gets it. The founder started strength training at 65. He walked into a gym, asked "lift what?", and got more answers than there were machines. So he went to the research and built this. Every feature exists because he needed it. Never been to a gym? Our First Visit Guide walks you through everything—what to wear, what to expect, the unwritten rules nobody tells you. Your first visit, you don't even exercise. You just look around. We go slow on purpose. Returning after years away? The app adapts to your experience level. Skip the beginner content and get straight to training with smart defaults based on your history. What makes Eureka Strength different: • Know What to Lift Today — Track soreness on a body map, and the app tells you which workout you're actually recovered for. No more wondering whether it's too soon for legs. • Weights Based on Your History — Suggestions come from what you actually lifted last time, adjusted for your rep target and counted per side on single-arm work. • Built for Real Bodies — Plans for falls prevention, bone density, and limited mobility. Tell the app about a joint replacement, balance concerns, or a wheelchair, and it adjusts what it suggests. • First Visit Guide — A 4-stage system that takes you from "never set foot in a gym" to training with confidence. Checklists, facility finders, etiquette primers—all personalized to you. • Evidence-Based — Every recommendation cites peer-reviewed research from ACSM, CDC, WHO, and major journals. Tap any research badge to read the actual study. No black boxes. No "trust me." • Smart Exercise Ordering — Compound movements first, stale exercises prioritized. You'll learn why this order matters—and see the research behind it. • Share With Family — Optional. Let an adult child or partner see that you're showing up, and nothing beyond what you choose to share. • Progress Tracking — Strength gains in clear graphs, with estimated 1RM. • Apple Health Integration — Workouts sync automatically with accurate duration tracking. Subscription: $4.99/month or $49.99/year 30-day free trial. Cancel anytime.
