Erg conditioning built for rugby power

By the Watta Team · Updated 10 August 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.

Rowing App for Rugby Players: Watta is a free, AI-powered rowing workout tracker. Snap your erg screen to capture data instantly. Get a 0-100 Effort Score combining cardiac load, work output, pacing, and economy. Track heart rate zones via the Karvonen method. Join clubs and squads to train with your crew.

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.

Frequently Asked Questions

Why do rugby players use rowing machines?

Rowing machines develop the posterior chain (glutes, hamstrings, back) which is critical for scrummaging, tackling, and sprinting. The erg also builds cardiovascular fitness with minimal joint impact — important for players managing contact-sport injuries.

What erg workouts are best for rugby conditioning?

Short, high-intensity intervals mirror rugby energy demands. Try 8x500m at maximum effort with 90 seconds rest, or 10x200m sprints with 30 seconds rest. Watta captures the data from each set so you can track conditioning progress over a pre-season block.

Can our whole squad use Watta together?

Yes. Create a club on Watta and invite your squad members. Every player logs their erg sessions individually, and all workouts appear in the shared club feed with Effort Scores and leaderboard rankings.

Every erg counts.
