Train531: 5/3/1 Strength Coach

Stop using a calculator disguised as an app. Every other 5/3/1 app does the same thing: you enter your maxes, it spits out percentages. When it comes to accessories, supplemental work, and what to actually do when you stall — you're on your own. Train531 is different. It's a 5/3/1 training app with an AI coach built in. SMART WORKOUT GENERATION Your warmup, working sets, and AMRAP are calculated from Wendler's proven programming. But your supplemental and accessory work is prescribed by AI based on your training history, available equipment, and goals. No more guessing what to pair with your main lifts. PROGRESS ANALYSIS Track estimated 1RM trends and weekly volume with clear charts. The AI coach analyzes your training data and gives you actionable feedback — not just graphs you have to interpret yourself. PERSONAL RECORDS Automatic PR detection using the Epley formula. Hit a new estimated max? You'll know immediately. TRAIN ANYWHERE Your data syncs across iPhone, iPad, and the web app at app.train531.com. Log a set on your phone, review your progress in the browser — always in sync.
