A fitness plan built for your body — see the result first
Every app sells you a workout plan. We build yours from your real numbers — exact calories, macros and a week-by-week schedule — and then show you the part nobody else can: an AI render of your body at day 90 if you follow it.

See your three futures
Your projected body at day 90 on the plan, on your current routine — and if you slip. Numbers AND images.
Follow a plan you've seen work
You're not training on faith. You've already seen where the plan takes you — now go get it.
Motivation dies when the result is invisible. That's why most plans get abandoned by week 3. BodyTimeline makes the result visible on day zero — your own body, rendered at day 90 — so every workout has a picture attached to it.

What's included in the personalized fitness plan?
Your exact daily calorie target, protein/carb/fat macros, a week-by-week workout schedule with specific exercises, sets and reps, meal-timing guidance, your single highest-impact habit change, weekly weight milestones for all 12 weeks, and check-in emails to keep you on track.
How is the plan personalized?
It's built from your answers — age, height, weight, training days, activity level, diet, sleep, and your goal (fat loss, muscle, recomposition). Your calorie and macro targets are computed from your real TDEE, and the training schedule fits the days you actually have.
How is this different from other workout plan apps?
Every app gives you a plan. BodyTimeline is the only one that shows you the body the plan produces — an AI render of you at day 90 on the plan, on your current routine, and if you slip. You see the outcome before you commit to the work.
Do I need a gym?
No — the schedule adapts to your training days and setup. Tell the builder how many days you lift and do cardio, and the plan is built around that.
Do I have to upload a photo?
The photo powers your AI body preview, but it's optional — you can skip it and still get your personalized plan numbers. Photos are private and never shared.
How much does it cost?
Building your plan preview is free. The full plan — all 12 transformation images, the complete week-by-week schedule, macros and check-ins — is a small one-time unlock. No subscription.
