Science-based lifting, made useful

Make every set count

OPTAL turns your training history into clear signals for progressive overload, muscle stimulus, fatigue, and plateaus, then helps you act on them in the next session.

01 · Training intelligence

Your whole body.
One clear signal.

OPTAL connects the sets you log to the muscles they train. Readiness, stimulus, and recovery become something you can see instead of something you have to guess.

01
CNS readiness

See how prepared you are to perform before the first working set.

02
Interactive body map

Understand which muscles are fresh, recovering, or carrying fatigue.

03
Training recommendations

Turn your recent work into a focused next-session decision.

02 · Effortless logging

Log your workouts seamlessly

Last performance and today's target sit together. OPTAL preloads the numbers, keeps the overload decision visible, and turns logging into one deliberate tap.

01
Beat one axis to overload

Add load, reps, or effort quality with your previous set in view.

02
Keep the next action in reach

The floating log control stays above the tab bar while you adjust the set.

03
Built around the next set

Adjust weight, reps, RIR, form, muscle credit, and side without losing workout context.

03 · Logging beyond the app

Your workout stays live.

Keep your workout moving without reopening the app. OPTAL keeps the next set and its key controls on the Dynamic Island and Lock Screen, so you can log, adjust, and get back to training with less friction.

04 · Tunable metrics engine

Your model.
Not a black box.

OPTAL shows its work. The in-app guide explains how logged sets become stimulus, local fatigue, CNS readiness, recovery, overload, and plateau signals using the values active in your engine.

01
15 curated controls

Tune the assumptions that matter, from stimulating RIR and secondary-mover credit to recovery and plateau windows.

02
Retroactive, non-destructive recalculation

Changes recompute every stat surface while your logged workouts remain untouched.

03
Algorithms explained in plain language

The guide reads the live engine values, so the explanation always matches the numbers OPTAL is using.

05 · Across the training block

Progress you can actually inspect.

Weekly stimulus, overload trends, exercise history, PRs, and consistency stay connected. You see what is moving, what is holding, and what needs attention.
