Log fast.
Lift more.
The gym logger that tells you exactly what to do next, shows you the math, and never guilts you.
Progress is a rule, not a mystery.
Every suggestion is a prefill you can override, computed on your phone by rules you can read. No ML, no cloud, no black box.
THE FULL RULE TABLE →You capped 12 × 30 on every set, so weight goes up and reps reset.
bar 45 + 2 × (45 + 5 + 2.5)
Day one comes prefilled.
Ryzenith seeds your first session from published strength standards and your experience level, then shows you exactly how it got the number.
The apps that hide this call it AI. Ryzenith calls it arithmetic.
Start with a structure that works.
Import any split in one tap and edit anything. Every preset arrives with sets, rep ranges, and a progression mode already chosen, so the coach starts working immediately.
Starter programs (Beginner Full Body, Intermediate PPL, PHUL, 5×5) come with real exercises and real starting numbers. Build a day yourself and Ryzenith suggests complementary and opposing movements from movement-pattern tags. Build Antagonist Day drafts a balanced session from your equipment in one tap.
It teaches the vocabulary, in place.
Ryzenith assumes you might not know what a split is, why warm-ups exist, or what push and pull mean, and explains each term where it appears. Tap a term like
Every exercise carries how-to text, not just an animation. No modals, no lessons, no bro-science.
Your phone stays locked. Your log doesn't.
One tap logs the set, the rest timer runs itself, and it mirrors to Apple Watch's Smart Stack.
See what you're working.
Hundreds of lifts with 3D demonstrations, and a weekly coverage view that shows which muscles are due.
Balance you can see, never a grade.
Deterministic ratios between opposing muscles and movement patterns, computed on your phone, shown with the math and a one-tap way to add a fixing exercise. Never a score, never a comparison to anyone else.
Your pulling volume is 40% below your pressing over 4 weeks. Rows or pull-ups would balance it.
Skip a day. Owe nothing.
Your split is a queue, not a calendar, so there is no missed Tuesday and no guilt copy anywhere. Recovery rules keep 48 hours between repeat muscle groups. Optional mesocycle blocks run a few build weeks into a lighter deload week automatically. Travel mode swaps your scheduled lifts to whatever equipment you have on hand, and restores your gym setup, and its history, the moment you switch back.
Ryzenith should just work for more people.
An optional mobility profile steers suggestions toward compatible movements for wheelchair users, limited mobility, and post-injury lifters, hiding what does not fit without deleting anything. It is options, not a separate mode, and it stays invisible unless you turn it on.
Ryzenith is a training tool with adaptive options, not medical advice. Clear your training with a professional you trust.
That is the whole privacy label. No account, no server — everything stays on your phone, with an optional iCloud backup you control.
