Is the widget really free?
Yes — fully free with no usage cap. Copy-paste the code onto your site. No signup, no API key.
How does the RPE calculator work?
The user enters their current load (kg), RPE (6–10), and optionally reps. The widget outputs next week's recommended load with the adjustment percentage and rationale. Rule of thumb: +7.5% if too easy (RPE ≤ 6), +5% at 7, +2.5% at 8, 0% at 8.5, -2.5% at 9, -5% at ≥ 9.5.
Is the ForgeSport link required?
Yes — the widget displays a "Powered by ForgeSport" footer with a dofollow link. That's the trade for a fully free professional widget.
