Expert Insight: Mechanical Tension
Hypertrophy is driven by mechanical tension on the muscle fibers. This happens most when the bar moves *slowly* involuntarily. **Grind Tracking:** RepLog allows you to note the "Grind" level of a set. Identifying those sets where the last few reps were a slow, shaking battle helps you identify which sets were truly effective for growth.
Frequently Asked Questions
Is soreness required?
No, but it's a proxy. We track soreness levels to help gauge recovery.
Can I swap exercises?
Yes, if a machine is taken, easily swap for an equivalent movement (e.g., Leg Press -> Hack Squat).
"Stop just moving weight. Start building muscle. Track the stimulus."
