5 Reasons lifters pair up with PersonalBestie
No membership to log your training
RP Hypertrophy is a subscription. If you already know your split, or follow one from a book, a coach, or a free template, PersonalBestie lets you log it without paying monthly for program-building features you may not need.
Grounded AI workout recaps
After each workout, PersonalBestie calculates volume and PRs deterministically and, for signed-in users, uses AI to read your notes (e.g. "felt shoulder twinge on set 3"), giving practical feedback grounded in what you actually logged.
Unlimited routines, no ceiling
Save as many routines as your training needs, including mesocycle variations, deload weeks, and accessory days, all free.
Custom exercises beyond lifting
Your training does not have to fit a fixed exercise library. Create your own exercises and activities, including cardio and bouldering, and include them in your routines and workout log alongside strength training. Use notes to add context about the session.
Connect your own AI with MCP
PersonalBestie exposes Model Context Protocol (MCP) endpoints. Connect Claude Desktop or another AI assistant to your workout history to review progress, spot trends, or draft the next block from your real logs.
When does the RP Hypertrophy App still make sense?
RP and PersonalBestie are not direct one-for-one replacements, and there are clear cases where RP is the better choice:
Frequently asked questions
Can I use an RP program and log it in PersonalBestie? ↓
Yes. PersonalBestie lets you create routines for any split, so you can log a program from RP or any other source. It will not auto-progress weights or reps for you the way the RP app does.
Is PersonalBestie really free compared to the RP Hypertrophy App? ↓
Yes. PersonalBestie is an open-source project. Unlimited routines, workout history, PR tracking, and routine sharing are free. The RP Hypertrophy App is a paid membership with a 30-day money-back guarantee.
Does PersonalBestie adapt my training based on soreness and pump? ↓
No. PersonalBestie does not adjust your program from pump or soreness ratings. After each workout, signed-in users get an AI recap based on their logged sets and notes, and you decide what to change.
Can I try PersonalBestie without creating an account? ↓
Yes. In guest mode, all your training data is stored directly in your browser's IndexedDB storage, and you can sign in later to sync it.
