FlexFlow is muscle-first. Select what you are training, choose your depth, get exactly the stretches you need โ deduplicated, ordered by coverage, and explained.
Every plan is editable. Replace any stretch with a targeted alternative. Add from the full library. Remove what doesn't fit. Save named plans for your regular training splits.
Quick mode gives the minimum effective dose. Optimised gives the best return on time. Custom lets you set exactly how many exercises per phase.
