Erg conditioning built for rugby power
By the Watta Team · Updated March 2026
The rowing machine is a staple of rugby strength and conditioning programmes — developing leg drive, hip extension, and cardiovascular fitness without pounding joints. Watta turns every erg session into structured data with AI screen capture and a rugby-relevant Effort Score that measures power output alongside cardiac load.
The Problem
Conditioning sessions lack structured data
Rugby S&C coaches prescribe erg intervals for conditioning, but players rarely track split times, stroke rate, or heart rate. Without data, it is impossible to measure conditioning progress or programme effectively.
Power development is hard to quantify on the erg
Rugby demands explosive power. Standard erg apps show split time but not watts per stroke, peak power, or the relationship between stroke rate and force — metrics that matter for power athletes.
Team conditioning lacks accountability
When a squad of 30 players does erg intervals, there is no easy way to compare outputs, track individual progress, or hold players accountable to conditioning targets between sessions.
How Watta Helps
Instant Interval Capture
Snap your PM5 screen after each erg conditioning set. Watta extracts every metric — split, distance, stroke rate, and calories — so your S&C coach has real data, not estimates.
Effort Score for Conditioning Load
The Effort Score rates each session from 0-100, combining cardiac load with work output and pacing. Perfect for monitoring conditioning load across a rugby pre-season programme.
Squad Leaderboards
Create a club for your rugby squad and track erg outputs on shared leaderboards. Drive competition and accountability during off-season conditioning blocks.
How It Works
Snap your erg screen
Take a photo of your PM5 display after your workout. Gallery upload works too.
AI extracts your data
Watta reads every metric — time, split, distance, stroke rate, heart rate, and calories.
Get your Effort Score
A 0-100 score combining cardiac load, work output, pacing, and economy shows exactly how hard you worked.
