Expert Insight: Work Capacity Tracking
In HIIT, "Work Capacity" is the primary metric. It's not just "did you survive the 60s?", it's "how many meters did you row in that 60s?" **Density PRs:** RepLog tracks your density. If you did 100 burpees in 10 minutes last week, and 9 minutes this week, that is a Density Personal Record. This is the truest measure of conditioning improvement.
Frequently Asked Questions
Can I customize intervals?
Yes, set any Work:Rest ratio (e.g., 20:10, 40:20) imaginable.
