Use any of the most popular 1 Rep Max formulas to estimate your 1 Rep Max weight and keep a log to see your progress over time. Simply select a lift type, enter a weight, and a number of repetitions (up to 10), and tap the Calculate button to see your 1 Rep Max. With My 1 Rep Max Premium, you can create your own custom lifts and use more than 10 repetitions to perform calculations. A Note About Safety: One rep maximum calculators are used to estimate the maximum amount you can lift. The degree of accuracy can vary significantly depending on your experience with weight training as well as your muscular composition. Most one rep maximum calculators are designed for experienced strength trainers so, if you are inexperienced, you may find your actual one rep maximum is much lower because your body is not accustomed to the stress of lifting heavy weight. Because it can be dangerous to attempt to lift your estimated maximum, always have a spotter with you. Seriously. My 1 Rep Max will never ask you for a rating or review. However, if you'd like to take the time to rate or review it, you can do so from the Settings screen. ## My 1 Rep Max Screenshots - [Screenshot 1](https://is1-ssl.mzstatic.com/image/thumb/Purple116/v4/09/6c/c3/096cc3f0-1360-ffae-3683-69a21480b217/mzl.mmrcagtl.png/1242x2208.png) - [Screenshot 2](https://is1-ssl.mzstatic.com/image/thumb/Purple116/v4/1d/b3/15/1db31514-544e-cfbb-a9ba-52be17f1f225/mzl.wntxdjvq.png/1242x2208.png) - [Screenshot 3](https://is1-ssl.mzstatic.com/image/thumb/Purple126/v4/14/06/f2/1406f286-5f4b-ec7a-0e91-fc308e4bc599/mzl.yksurcbd.jpg/1242x2208.png) - [Screenshot 4](https://is1-ssl.mzstatic.com/image/thumb/Purple116/v4/a6/82/bf/a682bfc0-0450-757f-dd60-239a115e1ab1/mzl.qqawghai.jpg/1242x2208.png) - [Screenshot 5](https://is1-ssl.mzstatic.com/image/thumb/Purple126/v4/d6/4e/de/d64ede0a-5188-26ce-6901-cc94dae44c69/mzl.ltnsfsgd.jpg/1242x2208.png) ## My 1 Rep Max Rating Breakdown in United States - 5 stars: 85 (75%) - 4 stars: 10 (9%) - 3 stars: 8 (7%) - 2 stars: 3 (3%) - 1 stars: 8 (7%) ## My 1 Rep Max Reviews in United States ### ***-- "No longer working" Updated all my apps and software on iPhone and this app is no longer working. Hundreds of data points that I cannot access. Would give 5 stars if this was fixed. About 2 weeks in waiting for response from App Store support. -- bukitikast, 2024-11-06 ### *---- "Buyer Beware" Buyer beware, the premium version doesn’t allow you to add new lifts as promised. -- Name.Not.Taken2574, 2024-03-08 ### *---- "Can't exceed 10 reps" Calculator won't go beyond 10 so pretty useless for high rep PRs -- Lee lapeyrouse, 2024-03-05 ### *---- "Crashing" Every time I try to enter my max on a lift, the app crashes. EVERY TIME. -- The Stew 8421, 2022-09-29 ### ***** "Very accurate" Accurate! -- liletvee, 2022-03-07 ### ****- "Great, but needs more lifts" Almost perfect...needs user-defined lifts! I would pay for that! -- slojpeg, 2019-08-11 ### ***** "More lifts needed" The simplicity of the app is the reason for the use. The only thing that could be added would be additional lifts. I.e. snatch, power snatch, power clean, clean and jerk. More Olympic lifts!! -- mchristmas35, 2019-06-22 ### ***** "🤙🏾" I’ve always relied on my former trainer to set the weights and or/ make it up as go along. This is a real time saver and helpful to know what numbers I’m going to smash next!! -- Savaii76, 2019-02-25 ### **--- "Cant enter double digit reps" Glitchy -- Gator joe5150, 2018-10-08 ### ***** "I use it with every workout!!!" I put every workout in this app and I love it! -- JoeyJoeJoseph123456, 2018-02-19 [View all My 1 Rep Max reviews and detailed analytics on AppTail](https://app.apptail.io/signup?utm_campaign=ai-crawl&utm_content=reviews) ## My 1 Rep Max In-App Purchases | Item | Price | |------|-------| | My 1 Rep Max Premium | $0.99 | ## My 1 Rep Max Discovered Keywords -
