Introducing Fitr’s New Fitness Calculators: Rep Converter, Percentage Table & Pace Estimator

Whether you're a fitness coach programming sessions or an athlete chasing personal bests, precision matters. That’s why we’ve built a powerful new feature into the Fitr coaching platform—Fitness Calculators—designed to streamline your training planning and give you data-driven insights in seconds.

Here’s what’s inside:

Rep Converter: Smarter Strength Programming

Programming strength work often involves estimating how a weight lifted for one rep might translate to multiple reps—or vice versa. Our Rep Converter takes the guesswork out of that process.

How it works

Simply enter a weight and the number of reps, and we’ll calculate the estimated equivalent for any rep range from 1 to 20 reps.

Example

If you can lift 100kg for 1 rep, the Rep Converter will estimate what you could lift for 8 reps: 81kg. This is incredibly useful for:

  • Coaches programming progressive overload
  • Athletes building towards 1RM testing
  • Clients tracking rep-max improvements over time

Percentage Calculator: Quick Training Intensity Insights

Need to quickly scale training intensity based on a known value? Our Percentage Calculator makes it effortless.

How it works

Enter a number—commonly your 1RM or max effort—and get a table showing 2.5% to 100% increments with the corresponding values.

Example

Input 200kg, and the calculator instantly shows you:

  • 80% = 160kg
  • 70% = 140kg
  • …all the way down to 2.5%

Perfect for:

  • Strength and hypertrophy programming
  • RPE-based training
  • Periodised training cycles

Pace Calculator: Plan Your Runs with Confidence

For endurance athletes and coaches, pacing is everything. The Pace Calculator helps you forecast finish times and set training targets with precision.

How it works

Enter a pace (e.g. 5:00 per km), and we’ll display your estimated finish times for key distances:

  • 1km, 5km, 10km
  • Half marathon (21.1km)
  • Marathon (42.2km)
  • And custom distances in both km and miles

It’s great for:

  • Runners, triathletes, and hybrid athletes
  • Coaches building cardio-focused programs
  • Clients preparing for race events
