People who train and want a coach in their pocket, not another app to manage

Fitness Coach

Chat-based training log for lifting, cardio, and mobility. Send a plate photo or a quick note — it does the math, tracks your progress, and tells you what to do next.

Outcomes

• Log every session — lifting, running, cycling, mobility — without opening a dedicated app
• See exactly how each lift, run, or practice is progressing over time
• Always know what to do next, based on where you actually are

What is included

How the agent works

• Direct, no-shame tone — like a training partner who keeps notes
• No medical advice; escalates pain and injury signals
• No diet or nutrition advice — that belongs to a nutrition agent
• Confirms assumptions before logging anything

Files you'll fill out

• Equipment rules: bar types, plate inventory, units, cardio gear
• Exercise and activity library with your own names and aliases
• Workout log, PR history, program template, and progression rules

Step-by-step workflows

• Plates-to-load calculation from photos or text inputs
• Cardio logging: distance, pace, heart rate, intervals
• Mobility check-ins: range, feel, time
• Progression: add reps → add load → deload triggers

Quick check: are we using a 20kg Olympic bar? If yes, and each side is 25kg + 10kg, that’s 70kg plates + 20kg bar = 90kg total. Want me to log this as your working set weight for Bench?

10 reps

Fitness Coach

Saved: Bench Press — 90kg × 10 (working set). Next: do you want to repeat for 2 more sets, or do a backoff set? (Your default progression rule: add reps until 3×10, then +2.5kg.)

Illustrative conversation preview. Plate math depends on your bar type and unit settings.

Context questions at startup

• What types of training do you do (lifting, running, cycling, mobility, etc.)?
• What units do you use (kg/lb for lifting, km/mi for cardio)?
• What bars and plates do you train with, if applicable?
• What are your current goals and how do you want to track progression?

Tools guidance

• image understanding for plate photos
• arithmetic and unit conversion between kg, lb, km, mi, min/km, min/mi
• structured logging into memory files
• reminder nudges and weekly summaries, optional

Training partner that logs your workouts and tells you what to do next. Handles lifting, cardio, and mobility. No diet or nutrition advice — that is a separate agent.
