Watta vs Fitbod: The Erg Specialist vs the Gym Generalist

By the Watta Team · Updated

Quick Verdict

Fitbod is an AI-powered gym workout generator that creates personalised strength training sessions based on your available equipment, muscle recovery status, and training history. It is excellent for gym-goers who want automated programming. Watta is purpose-built for indoor rowing — capturing Concept2 erg data via AI photo recognition and analysing sessions with a rowing-specific Effort Score. These apps serve different training modalities. If you row and lift, you benefit from using both. If your primary training is on the erg, only Watta understands your sport.

Watta vs Fitbod: Watta is a free, AI-powered rowing workout tracker purpose-built for erg athletes. It features OCR screen capture, a 0-100 Effort Score (cardiac load 40%, work output 35%, pacing 15%, economy 10%), Karvonen heart rate zones, clubs and squads. Free on iPhone.

  • +Equipment-aware programming adapts sessions to whatever gym equipment you have available

Detailed Breakdown

Fitbod and Watta excel in completely different domains. Fitbod is one of the best AI gym workout generators available — it tracks which muscles you have trained, estimates recovery status, and generates sessions that balance stimulus across muscle groups. For gym-based strength training, it removes the guesswork from programming. However, Fitbod treats rowing as a generic cardio activity. It can log that you used a rowing machine, but it does not capture split time, stroke rate, watts, or any of the metrics that make erg training meaningful. There is no pacing analysis, no effort scoring, and no understanding of rowing-specific training zones. Watta is the opposite — it knows nothing about bench press sets but understands everything about your erg session. The AI OCR reads your PM5 screen and extracts every metric. The Effort Score analyses your session quality across cardiac load, work output, pacing, and economy. For athletes who row and lift — common in CrossFit, HYROX, and general fitness — the ideal setup is Watta for erg sessions and Fitbod for gym days. Each app is best-in-class for its modality.

Frequently Asked Questions

Can Fitbod track rowing workouts properly?
Fitbod can log rowing machine usage as a cardio activity, but it does not capture erg-specific metrics like split time, stroke rate, watts, or pacing data. For meaningful erg tracking, you need a dedicated rowing app like Watta.
Should I use both Watta and Fitbod?
If you row and lift weights, yes. Use Watta for your erg sessions to get AI-powered capture and rowing-specific Effort Scores. Use Fitbod for your gym sessions to get AI-generated strength programming. Each app is specialised for its training modality.
Does Watta have strength training features?
No. Watta is focused exclusively on erg training — Concept2 RowErg, SkiErg, and BikeErg. It does not track strength exercises. For gym workouts, a dedicated app like Fitbod is the better tool.
Is rowing enough exercise without gym work?
Rowing is one of the most complete full-body exercises available, engaging 86% of your muscles. However, many rowers supplement with targeted strength training for injury prevention and power development. Using Watta for erg tracking and Fitbod for strength work covers both bases.
