FitHarness is a training and nutrition system of record you operate by talking to Claude. Plan your blocks, log your sets, reconcile your macros, and build a complete fitness plan and experience — all through the ease of conversation.
30 days free, then $30/month. Cancel anytime.
Claude brings the judgment. The app owns the numbers — macro reconciliation, estimated 1RM, volume accounting and injury rules — enforced in code, not prompts. Take advantage of what it already knows about you, backed by a powerful MCP server that keeps track of every plan, set and meal.
One record for the whole picture — strength, conditioning, food, bodyweight and recovery — so nothing has to be reassembled by hand.
Periodized blocks with per-lift target weights back-solved from your logged e1RM at the prescribed reps and RPE.
Metcons, benchmark WODs, runs and rows — tracked with pace and PR context, separate from lifting.
Log meals by photo or a sentence. Calories are reconciled against the macros behind them and corrected when they don't add up.
Weigh-ins with a trailing trend, so a single noisy reading never moves anything on its own.
Sauna and cold plunge logged as recovery — never counted as training volume.
Sets per muscle and movement pattern, push:pull and squat:hinge ratios, over any window you ask for.
No commands and no syntax to learn — anything you'd say to a coach is fair game, including arguing with the programming. A photo works too.
“Here's my hotel gym for the week — how should I change my next three days?”
“I want to switch goals and train for a marathon instead. Let's build a plan together.”
“Ordering from Velvet Taco tonight — what should I get to fit my macros?”
“They didn't have a cable fly, so I'm using this machine instead.”
“I'm feeling run down. Should I skip today, or what can I sub in?”
“Here's my most recent blood work — how should I adjust my diet?”
“How much hamstring work have I actually done this month?”
“My left elbow's acting up. Keep training arms, but work around it.”
“What should I order from this menu to hit my protein target?”
“That took an hour and fifteen — close out the session.”
“Am I still on track to peak for my meet on March 1?”
“I've only got 30 minutes today — give me a shorter version.”
Name and email only — no Gmail, Drive, or Calendar access.
Paste one URL on a computer; it then works from your phone.
Tell it your goal and training days — it writes your first block.
The connector is added once from the Claude desktop app on a computer (custom connectors need a paid Claude plan) — after that it works from your phone.
