Your coach, built
from your data.

Bite builds your plan, pre-fills your workouts, progresses your weights, tracks muscle recovery, and adjusts nutrition targets from the work you log.

How Bite works

Simple for the lifter. Serious underneath.

The app is built around one loop: plan the work, log what happened, then turn the pattern into the next useful coaching action.

01

Build the plan

Tell Bite your goal, schedule, equipment, experience, focus muscles and recent training. It returns a week you can actually follow.

split, exercises, sets, reps, rest days
02

Train with less friction

Open today, tap start, and log the set. Weights are pre-filled from your history, and RIR tells Bite how hard the work really was.

weight, reps, RIR, swaps, adherence
03

Let the coach adapt

After sessions and blocks, Bite watches progress, plateaus, fatigue, readiness, nutrition and bodyweight before changing the plan.

In the app

Open the app. Your next step is already there.

Bite turns coaching into specific moments: start today's workout, follow the pre-filled targets, review the change, then approve what updates.

Evidence first. Change second.

Every training day is already built. Bite brings the right exercises, target sets and previous weights into the workout so you can focus on the lift, not the spreadsheet.

Evidence first. Change second.

Every session becomes context. Bite remembers what progressed, what stalled, what you swapped, where fatigue built up and how the next block should change.

Program generation

A real program before the AI starts talking.

Bite starts with your profile, chooses the right split, allocates weekly sets, fills exercise slots and validates the plan before coaching begins.

iPlan generation follows deterministic checks before it becomes adaptive or mesocycle coaching.

Nutrition adaptation

Calories and protein adjust to goal pace.

Bite compares bodyweight trend, logged intake, adherence and target rate before it changes calories or macros.

Target calibration

Goal pace is slightly slow.

Because weight is moving under the target band while logging is consistent, Bite raises calories and keeps protein stable.

Calories2,650 to 2,780 / day
Protein180g locked

Coach Engine

The engine watches the patterns you would miss.

Each node maps to a real backend signal. When training or nutrition needs attention, Bite prepares the change and asks before applying it.

Bite

Bench Press has stayed at 80kg for 3 sessions while reps were completed. Calories are also slightly below goal pace. Apply the next update?

Applied. Upper A now targets 82.5kg on Bench Press, and calories move to 2,780/day. Bite will watch the next exposure and weigh-ins before changing again.

Coaching loop

Every recommendation has a trail.

The AI explains the change, and every suggestion starts from structured training, recovery, bodyweight and nutrition data.

Log

Session logged

Sets, reps, weight, RIR, swaps and completed sessions become the evidence layer.

Detect

Pattern detected

Bite checks plateaus, fatigue, volume gaps, adherence, bodyweight trend, nutrition and readiness.

Prepare

Change prepared

The backend computes the exact payload: weight, sets, exercise, deload, calories or macro target.

Apply

User approves

One tap applies the recommendation to the active plan instead of leaving it as advice.

Decision layer

Signals go in. Plan changes come out.

Training, nutrition, recovery and bodyweight only matter when they lead somewhere. Bite connects those signals to the next useful coaching action.

Beta access

Start training with a coach that remembers the work.

Built for lifters who want more than a plan PDF: a system that watches the trend, explains the change and updates the plan when you approve.
