About Level
An AI coach that actually coaches.
Level exists because most fitness apps hand you a generic plan and walk away. The good ones cost hundreds a month and still can't see how you're actually training. The great human coaches cost thousands a year and have waitlists.
We thought the job of a coach — translate decades of exercise science into the right program for this person, this week, with this data — was a job AI could finally do well. Level is that coach.

How we program
Level isn't a random workout generator. Every plan applies the same principles a good strength coach would use — but for you, from your data, continuously.
Periodization, not random workouts
Every program Level builds moves through hypertrophy, strength, and peaking blocks. Your training load, rep ranges, and volume land on a plan — not a mood.
Progressive overload, measured
We track every set. If you're stalling, Level adjusts loads, rest, or volume before you plateau. If you're ahead of pace, it pushes harder.
Deloads based on fatigue, not the calendar
Recovery weeks fire when your data — logged RPE, missed reps, subjective readiness — says you need one. No more pre-scheduled easy weeks you don't need.
Nutrition that matches your training
Macro targets shift on training vs. rest days. More carbs when you need them, slightly less when you don't. Calories tied to a real body-comp goal, not a generic TDEE guess.
Coaching that adapts to your level
Beginners get simple instructions and volume ramps. Intermediates get RPE and exercise substitutions. Advanced lifters get volume landmarks, block periodization, and peaking protocols.
The science behind it
Level's coaching logic is grounded in the same frameworks used in strength & conditioning literature and sports nutrition research.
Progressive Overload & Periodization
Programs draw on the principles of undulating periodization (DUP), block periodization, and linear progression — standard frameworks in strength & conditioning literature.
RPE & RIR-Based Load Prescription
Rate of Perceived Exertion (RPE) and Reps in Reserve (RIR) let Level prescribe load based on how you actually feel that day, not a fixed percentage of an outdated 1RM.
Volume Landmarks
Weekly set counts follow established MEV/MAV/MRV ranges from hypertrophy research — enough to drive adaptation, not so much that recovery suffers.
Evidence-Based Nutrition
Macro targets come from peer-reviewed recommendations on protein intake for trained individuals (1.6–2.2 g/kg), energy balance for recomposition, and carbohydrate periodization around training.
Our mission
“Put a coach-level fitness experience in the pocket of anyone who wants one — for less than the cost of a single personal training session.”
