Strength Cycle

Features
Read full description

Built for serious lifters running structured strength programs. Strength Cycle handles 5/3/1, 3x5 Strength, and Texas Method with the rigor each methodology demands. No generic templates. No bolted-on assumptions. Every program implemented with full methodology fidelity: - 5/3/1 — Wendler's percentage-based system with proper Training Max management, AMRAP top set logging, and complete 4-week cycle phases (5/5/5, 3/3/3, 5/3/1, deload). - 3x5 Strength — Linear progression for intermediate strength building, with smart deload triggers when progress stalls. - Texas Method — Volume/recovery/intensity weekly progression with PR-driven Training Max updates. MORE PROGRAMS COMING Strength Cycle is built program-first. More proven strength programs are in active development — each implemented with the same methodology fidelity as the three above. No half-baked templates, no generic "add your own program" placeholders. WHAT YOU GET - Exact prescribed percentages, never rounded into uselessness - AMRAP top set logging with automatic e1RM calculation (Epley formula) - Training Max progression tracked across cycles, with full phase context - Deload weeks handled with proper percentages — not skipped, not faked - Workout history filterable by lift, cycle, and phase - e1RM trend charts per lift across all cycles - Ask Coach — in-app assistant for AMRAP interpretation, TM management, assistance work selection, deload decisions, and program-specific programming questions BUILT BY A LIFTER Strength Cycle was built by a 30+ year lifter who got tired of programming apps that misunderstand the programs they claim to support. If you've ever rolled your eyes at an app rounding 67.5% to "70% — close enough" or skipping deloads entirely, this is the one that gets it right. FREE, NO SUBSCRIPTIONS, NO ADS Strength Cycle is free to download and use. No subscription tiers. No paywalled programs. No ads. Just the programs, done right.

The Find Your Program quiz picks the best match for your goal, experience, and schedule in under a minute. MUSCLE FRESHNESS Every exercise row carries a recovery dot, green, yellow, or red, so you know which movement patterns are ready for another hard session. Tap in for a per pattern recovery bar, last loaded time, and the workouts that contributed. STRENGTH STANDARDS See where your Squat, Bench, Deadlift, and Overhead Press rank against the rest of the lifting population, adjusted for your bodyweight, age, and sex. Per lift progress bars show how far you are from Intermediate, Advanced, or Elite. RECOVERY INSIGHTS Connect Apple Health and the app watches your HRV, sleep, and recent training load. When recovery looks reduced, a banner on Home suggests a lighter day. Every past alert stays in Progress so you can scroll back through the data that drove every recommendation. LIFT, LOG, DONE One tap set completion with a crisp haptic click. Auto calculated warmups. Plate math that respects the plates you actually own. Rest timer that auto starts when you finish a set.

Nest LEVIASUNS, an nSuns variant, or your own coach's block in minutes. Export the whole program (or a program + history bundle) as a single .ironprog file, share it, and import on another device without losing a set. BODYWEIGHT, DONE RIGHT Pull ups and dips accept signed weights (+25 for a belt plate, −40 for band assistance) and factor your real bodyweight into total volume. Push ups and planks just track reps. WATCH + HEALTH Track workouts on Apple Watch: start a set on your wrist, see the rest timer tick down, end the workout without pulling out your phone. Optional auto RPE suggestion from heart rate recovery (beta). Workouts sync to Apple Health as strength training sessions. Body weight, heart rate, and calories flow both ways.
