Common problems Spotter helps make visible
Only filming PR sets
Form trends show up best when you analyze normal working sets, not just max attempts.
Ignoring camera setup
Clear framing matters because form analysis depends on visible movement landmarks.
Chasing scores instead of changes
The goal is better movement over time, not a perfect number after every set.
Workout form analysis questions
What is workout form analysis?
It is the process of reviewing exercise movement for range, tempo, consistency, and completion quality so you can improve how you lift.
Can AI analyze my exercise form?
Spotter can analyze supported movements using browser-based computer vision when your camera setup clearly shows the lift.
Is Spotter for beginners or advanced lifters?
Both. Beginners can use it to learn consistency, while experienced lifters can use it to catch fatigue-related form drift.
