They Treat Logging As The Activity
Open app, select exercise, enter weight, enter reps, tap save. Four steps per set, five sets per exercise, six exercises per session. That's 120 taps minimum. You're not training. You're doing data entry with barbells.
They Don't Know What You Planned To Do
Strong and Hevy track what happened. They have no concept of what was supposed to happen. When you skip a set or swap an exercise, the log doesn't know the difference between "I chose to deviate" and "this is what I always do."
They Reset Every Block
Your training log from last mesocycle is a wall of numbers. There's no summary, no trends, no "here's what changed and why." Starting a new block means scrolling through history and trying to remember context that was never recorded.
They Optimize For Logging, Not For Training
The best session tracking system is one where the log is a side effect of doing the workout. You finish a set, you tap complete, you move on. The system captures the data. You never feel like you're being asked to log.
