XFornax Strength
Track more of what matters — without clutter. Sets, series, rest, when you trained, PRs, total volume, muscle-specific volume, and work capacity.
Complexity simplified. Depth preserved.
Most apps log sets and stop. XFornax Strength is built for people who want to understand training load — total and by muscle — without fighting the UI between sets.
100+ catalog
Machines and free-weight staples with primary & secondary muscles mapped.
