Gym Tools & Calculators
Optimize your hypertrophy training with our free suite of calculators. Stop guessing and start tracking with precision.
Effective Reps Calculator New
Are you doing “junk volume”? Calculate exactly how many muscle-stimulating reps you perform per set based on your RIR (Reps In Reserve).
1RM Calculator
Estimate your One-Rep Max safely without testing it. Uses the Epley and Brzycki formulas to predict strength potential from sub-maximal lifts.
Volume Load Tracker
Visualize your weekly tonnage per body part. Ensure you are applying progressive overload week over week.
Why Use Training Calculators?
Training for hypertrophy isn’t just about moving weight from point A to point B. To maximize muscle growth, you need to track specific metrics like proximity to failure (RIR) and progressive overload.
We built these free tools to help you visualize the data that matters. While these calculators are great for spot-checking your intensity, the Strive Gym Log app handles all of this math for you automatically in the background while you train.
