General fitness information — not a replacement for a certified trainer
This AI generates general exercise programming. Consult your doctor before starting a new program, especially if you have heart, joint, or pregnancy-related concerns. Work with a certified personal trainer (NASM, NSCA, ACE, ACSM) for supervised technique and injury management.

No. Free.ai generates general programming. A certified trainer (NASM, NSCA, ACE, ACSM) watches your form, regresses exercises for injuries, and progresses you with hands-on feedback. Use Free.ai for the plan skeleton; pair it with a trainer, a form-check app, or a quality YouTube movement library.
Pick the preset that best fits (build muscle, fat loss, strength 1RM, cardio endurance, athletic power, mobility, general fitness, recomp, 10K / half / full run, postpartum return, senior functional), then describe specifics in the text box ("prep for powerlifting meet in 16 weeks", "cut 10 lb while preserving squat numbers"). The plan adapts to both.
Nine equipment presets: full commercial gym, home gym (barbell + rack), dumbbells only, kettlebell only, bodyweight only, resistance bands, suspension trainer (TRX), cardio machines, outdoors. The plan is built around what you have — no "you need a cable stack" when you are training in your basement.
Yes — put your injury or limit in the constraints field ("left knee, avoid deep flexion"; "shoulder impingement, no overhead press") and the AI substitutes or regresses. For structural injuries or post-surgery rehab, see a physical therapist BEFORE starting any program, AI-generated or not.
Four preset lengths: 4-week starter, 8-week progression, 12-week progression, 16-week periodized block. Longer plans build in a deload week and progressive overload rules. You can re-generate with the same inputs for a fresh variation, or ask for a new block after completing the current one.
Briefly — general caloric + macronutrient guidance aligned to your goal. For detailed nutrition planning, pair with /health/diet/ (Free.ai diet planner), /health/nutrition/ (per-meal analysis), or a Registered Dietitian (RD / RDN). Lifting for hypertrophy without a matching calorie surplus usually stalls.
Fitbod ($12.99/mo) and Freeletics ($79.99/yr) have native logging, timers, and video demos. Caliber ($199/mo) pairs you with a human coach. Free.ai generates the plan; it does not ship a logger. Use Free.ai free, export the plan to Notion or a fitness tracker, and log there.
The AI selects standard, commonly-used exercises and includes form cues, but it cannot watch your lifting technique. The biggest risk in any program — AI or not — is loading bad form. Film compound lifts (squat, deadlift, bench, overhead press), compare against form libraries like Renaissance Periodization or Juggernaut, and regress weight if your technique breaks down.
Yes — pick "Beginner (<6 months)" and a 3- or 4-day frequency. The AI defaults to full-body splits, conservative loads, and basic progressions (add 5 lb/week or 1 rep/week) that match what a good beginner program should look like. Learn form first, chase weight later.
Postpartum Return is a preset option, but any pregnancy or postpartum training REQUIRES medical clearance from your OB-GYN and ideally a pelvic-floor PT. AI programming is a starting skeleton — your clinician and PT own the specifics of safe return-to-training.
Yes — "Run 10K / half / full" preset generates a structured running plan with base miles, tempo runs, interval sessions, long runs, and rest days. For highly competitive goals (sub-3-hour marathon, Boston qualifying), pair the AI plan with a coach (Runner's World, McMillan Running Calculator) and a GPS watch to track effort.
Yes — POST to /v1/chat/ with your system prompt + inputs, or use the developer API at /developer/. Integrators build AI-first fitness apps on top of Free.ai's endpoint, billed at your token rate. Full OpenAI-compatible snippets in Python, Node, cURL at /api/.
