Mesostrength is a hypertrophy training app for lifters who run mesocycles and are tired of managing their own periodization.

Answer three questions — your training days, the muscles you want to grow, and the equipment you have — and Mesostrength writes a complete mesocycle in under a minute. No spreadsheets, no evening of admin before you touch a barbell.

Then it keeps working. After each muscle group you train, one tap records how the pump, the soreness and the effort felt. Mesostrength reads that feedback alongside what you actually logged, and rewrites next week's sets and working weights from it. Volume climbs where you're recovering well. It backs off where you're not.

WHAT YOU GET

- Automatic mesocycle design — training days, split, exercises and starting volume, built around your priorities
- Weekly volume and load adjustment driven by your recovery feedback and logged performance
- Per-muscle priorities, from prioritize to maintain, with weekly sets tracked from MEV to MRV
- Weight, rep and RIR targets set for every session, so you never guess what to lift
- Fast workout logging built for the gym floor, not the desk
- Progress analytics — estimated 1RM trends, volume by muscle group, bodyweight over time
- An exercise library with 280+ movements, plus your own custom exercises, form videos and notes
- An AI coach that has read every set you've logged

THE AI COACH

Ask why your bench stalled, whether your back volume is enough, or what to do about a shoulder that's been complaining. It answers from your actual training data, not generic advice — and it can propose changes to your program, which only apply when you approve them.

WHO IT'S FOR

Intermediate and advanced lifters who already understand progressive overload and periodization, and want the programming handled without giving up control. You can edit anything it builds: swap exercises, change days, adjust priorities, or build a mesocycle from scratch.

Not for absolute beginners. If you're new to lifting, a simpler program is a better starting point.
