A workout generator that knows how you slept

What goes into each workout

• Recovery: muscles you trained hard two days ago wait; fresh ones go first
• Readiness: sleep, heart rate variability and resting heart rate from Health Connect or Apple Health, plus how you feel, decide push, as planned or go easy
• Your gym: only exercises your equipment allows, with weights your plates and dumbbells can make
• Your time: pick the length and the plan fits it, warm-ups and rest included
• Your block: which week of the training block it is, and whether a deload is due
• Variety: a setting for how much exercises change from week to week

Not a chatbot

Liftsmith isn't a language model writing workouts. It's a planner built on training rules from research: weekly sets per muscle, rep ranges, reps in reserve, recovery time and progressive overload. That makes it repeatable, and every recommendation comes with a short, honest reason, like "Chest is 90% recovered" or "You hit all your reps last time".

You stay in charge

Swap any exercise for one that trains the same muscles, change the length mid-workout, or skip a day and the plan reshuffles. Prefer a fixed plan? Every classic program is free, and your own routines get the same automatic weights.

Questions

Is it an AI workout generator?

It's a planner built on training rules, not a chatbot. It uses your own data (recovery, readiness, history) to choose exercises and weights, and says why for each.

Do I need a smartwatch?

No. Readiness works from a quick how-do-you-feel. A watch or ring that writes sleep and heart rate to Health Connect or Apple Health makes it sharper.

What if I don't like an exercise?

Swap it in a tap for one that trains the same muscles with your equipment.
