A free fitness app that
actually plans for you.
Most free workout apps hand you a library of exercises and leave the planning to you, which is the part you wanted help with. Phasebuilt does the opposite: you answer questions for about a minute and it writes the whole ninety days.
Why it is free
There is no account, no email capture, no trial that expires and no paid tier waiting behind the result. Your answers are processed in your own browser, which is also why there is nothing to charge for: no servers storing your data, no subscription to administer. If that changes it will be stated plainly on this page rather than discovered at a paywall.
What personalization actually means here
Not a template with your name at the top. Your answers change the output in specific, checkable ways:
- Goal
- Fat loss, muscle building or general fitness, which sets the calorie direction and the training emphasis
- Your measurements
- Height, weight, age and sex feed a published equation to estimate your energy needs
- Equipment
- Full gym, home gym, resistance bands, or bodyweight with nothing at all
- Schedule
- 3, 4, 5 or 6 days, with the split built around that number
- Food
- Balanced, high protein, vegetarian, vegan or low carb, plus allergies and dislikes
- Recovery
- Sleep and stress, which adjust how aggressive the plan is allowed to be
Workouts and nutrition together
Training creates the demand and food supplies what it needs, so planning one without the other is how most attempts stall. You get sessions for each phase and daily calorie, protein, carbohydrate and fat targets calculated from the same set of answers, with meals to match your diet preference.
Built in three phases across ninety days
Foundation, Build and Perform, thirty days each. The demand changes as you adapt instead of asking you to repeat one routine for three months. The method behind the phases is set out in full.
If you have never trained before
That is the case this was built for. The first phase deliberately holds back, so you finish sessions able to repeat them. There is a plan for beginners that goes into what the first month looks like.
Works in the browser, anywhere
There is nothing to install from an app store. It runs on a phone, tablet or desktop, and the finished plan can be downloaded or printed so you can take it into a gym with no signal. Phasebuilt is available worldwide.
