A.I. hybrid training · Est. MMXXVI
Stadia is an A.I. coach for athletes who train across disciplines — strength, endurance, mobility, recovery. Built on Tactical Barbell and 5/3/1. Not a wellness app.
Every app on your phone was built for a single discipline. Run faster. Lift heavier. Recover better. They don't talk to each other, and they don't know what you did yesterday. You end up as your own head coach, stitching together a plan from four conflicting programs and a Reddit thread.
Stadia is one coach with the whole picture. It reads your Garmin, your Strava, your Oura. It writes the week. It rewrites it when your HRV tanks. It speaks the language of periodization because it was built by people who read The Science and Practice of Strength Training for fun.
Tell it what you're training for. A hybrid half in May. Powerlifting meet in the fall. Both. It asks the right follow-ups.
You get a 12-week block with Base, Build, Peak, Taper phases. Every session written out — squat weights, run paces, intervals, long days.
Garmin and Strava auto-sync. Oura feeds in recovery. Log a lift from your phone between sets. The week closes out on Sunday.
Missed Wednesday? HRV red for three days? The coach rewrites the week. The plan isn't a PDF — it's a living conversation.
No menus. No form-fills. Everything the coach does — and everything you wish it did — happens by talking to it.
Found a template you want to run? Paste it. The coach reads the article and writes a periodized plan calibrated to your current numbers.
Tell it when you can actually train. Hotel gym, Wednesday board meetings, the long run you have to move to Friday — say it in plain English. The plan reshapes.
Report bugs and request features by chatting — the same way you plan training. The most-upvoted issues get fixed first. The most-requested features ship next.
No vague “easy run” or “strength day.” Every session is written with intent — load, zone, reps, rationale. Here's a sample week mid-Base.

Periodization isn't a buzzword — it's the only reason you don't plateau. Stadia plans in blocks: Base, Build, Peak, Taper. Every week fits a phase. Every phase fits the goal.
K. Black's Tactical Barbell for concurrent strength + conditioning. Jim Wendler's 5/3/1 for pure strength progression. Proven by operators, lifters, and people who don't have time for seven-days-a-week Instagram splits.
No wearable cult, no lifestyle brand, no wellness bingo. The coach will push a Z2 hour when you want intervals, and cut your squat volume when your sleep tanks. That's the job.
Free to try. Bring your own goals. The coach will do the rest.
