What it is

FITNESS OS by Harrison (NotionByHarrison) is a workout and fitness tracker for Notion. You plan workouts, log them from your phone and watch lifts and performance improve over time. The listing says it is built with coaches and was updated for 2025 with a new phone view and a stronger progress tracker.

What's inside

• Workout builder with four formats: regular, timed, interval and AMRAP
• A library of 100+ exercises with example images, plus recovery and warm-up routines
• Workout logging with quick-action buttons and a phone view you can start from your home screen
• Exercise progress tracking: starting best, current best and growth percentage per lift
• Body measurements and weekly progress photos
• A challenge creator plus pre-made challenges (from 30-day abs to the Murph)
• Calendar, goals and resources; the screenshots also show a nutrition planner with macro targets and meals

Who it's for

Gym-goers and home trainers who want their log, programme and progress in one place and already use Notion daily.

What it doesn't do

It does not sync with Apple Health, Garmin or Strava; logging is manual. The fuller nutrition and body-tracking tools are sold as a separate upgrade, Health 360 ($49). It works on the free Notion plan, per the listing.

Price

$29 is at the top of fitness templates in our pool (median $20, most $12–27). 530 sales and 22 five-star ratings make it the best-selling product in this set.

Our take

The most proven fitness template we list. If you lift and like data, it is worth the extra few dollars over a basic workout log. Comparing options? Browse more Notion fitness templates.
