ULTMT App vs Row Downstream

Build muscle, lose fat, and take your physique to the next level with the ULTMT App. Everything you need to train smarter, track your progress, stay accountable, and achieve long-term results - all in one app. Designed for serious lifters, the ULTMT App combines training, nutrition, progress tracking, community, and education into one streamlined experience - so you can spend less time managing your plan and more time executing it.

Downstream turns your Concept2 erg into a coached training system. Pick from a catalog of hundreds of workouts or build your own and save them to your library — filter by training zone or duration. Drop them onto your calendar and each day's session is waiting for you, ready to row. While you pull, Downstream drives the workout: live pace and stroke-rate targets, split-by-split feedback, intervals and rest, and a customizable live screen. Every workout is captured — splits, strokes, and heart rate — and lands in your log automatically. • Works with any Concept2 erg (RowErg, BikeErg, SkiErg) over Bluetooth • Verified sync to your official Concept2 Logbook • Heart rate from a chest strap or your Apple Watch — free • Import your on-water rows, bike, and run activities from Strava • Start a Spotify playlist automatically when you begin a piece • Share-ready workout summary cards No ads.
