Strength,engineered.
Lift writes adaptive resistance programs from your training history, recovery signals, and goals — and gives you precise tooling when you'd rather drive.
Programmed for you. Or by you.
Both modes share the same logging, analytics, and exercise library. Switch any time — even mid-program.
AI Programming
Specify your goal, schedule, and equipment. Lift composes a periodized block, manages volume and intensity, and recalibrates after every session.
- Periodization: linear, undulating, block
- Auto-regulation via RPE & velocity
- Deload detection from HRV + sRPE
- Substitutes exercises by equipment & fatigue
Manual Build
When you know exactly what you want. A precise builder for sets, reps, tempo, rest — with the same logging and analytics underneath.
- Drag-to-order supersets and circuits
- Tempo, rest, and intent per set
- Saved templates and program forks
- Plate math and unit conversion
What a Lift program looks like.
An intermediate hypertrophy block, week 3 of 5. Generated for a 4-day upper/lower split with full-gym equipment.
Volume, intensity, and recovery — visible.
Tonnage by muscle group, e1RM trends, and adherence at a glance. No vanity metrics.
