Description
Stronger Training, Smarter Progress
One Rep Max helps you safely and accurately determine your maximum lift potential for bench press, deadlift, squat, and any other strength exercise - without risking injury.
Key Features: • Precise Calculations - 7 scientific formulas for accurate strength predictions: Epley, Brzycki, Lombardi, Mayhew, McGlothin, O'Conner, Wathan • RPE Integration - Factor in Rate of Perceived Exertion to fine-tune your max estimates based on how difficult sets feel • Custom Exercise Tracking - Create and monitor any lift that matters to you • Visual Progress - Beautiful graphs show your strength journey over time • Percentage Charts - Quick reference guide for training percentages • Goal Setting - Set targets and track your path to reaching them
Perfect for: • Powerlifters optimizing their training cycles • CrossFit athletes tracking multiple movement patterns • Olympic weightlifters monitoring progress • Strength enthusiasts at any level
Advanced Features: • Choose between multiple calculation formulas for different lift types • Track unlimited exercises with custom notes • Rate of Perceived Exertion (RPE) - Fine-tune your 1RM estimates based on how difficult sets feel • Analyze detailed statistics including volume and frequency • Set and monitor progress toward specific strength goals
The Science Behind The Numbers: Our app employs multiple validated formulas to estimate your one-rep maximum based on your performance with submaximal weights. This provides you with safe strength targets before attempting potentially risky maximal lifts.
Safety Note: Heavy weightlifting should always be performed with proper technique and appropriate spotting. This app provides estimates based on scientific formulas, but individual performance may vary based on experience level and training history.
Recent changes: A smoother way to log. We've cleaned up the flow throughout the app, so adding a lift, updating a max, and checking your history all take fewer taps and less hunting around. Clearer screens, the numbers that matter easier to read at a glance, and less scrolling to get where you're going. Plus the usual polish, performance improvements, and bug fixes.

★★★★★Sandy Arbuckle· Apr 23, 2024
Great, especially for me, I work out by myself and if I don't have any spotter I just do a nice weight and round it off to my max.♥️👍🏾

After downloading app Will Not Start. Tried to uninstall and re downloading it. Waste of time

Ive used this app for a while. While trying ro clean up space on my phone I noticed this app was taking over 225mb of space, after I cleared the cache and data. I uninstalled and reinstalled, it states on the play store app page its 36mb. After installed it jumped to 75mb without even opening the app. It's a good tool but so many out there that are less resource hungry. Bummer because I liked this app.
★☆☆☆☆Kamaka Baculpo· Feb 9, 2022
Was awesome when they first started now the app won't even open. I even paid for the pro version to log my lifts and keep track. I mean could it be just the android version? I switched from my iphone to the fold so iono maybe it's just not compatible with the fold.
